Hyundai Solaris brake fluid: what type and when to change? Replacing the working fluid in the hydraulic brake system of Hyundai Solaris Brake fluid Solaris 1.4.

Maintenance of each, even the most inexpensive car, is carried out strictly according to the regulations established by the manufacturer. Nevertheless, the item on replacing the brake fluid has disappeared from the Hyundai Solaris maintenance list for the last two years. This is due to many nuances, but the main one is the reduction in the cost of scheduled maintenance.

However, it is necessary to change the fluid, and today we will figure out how to do this, what kind of fluid is used in the system and when replacement is necessary.

In order for the brake system to work as efficiently as possible, the fluid that is filled into it must have a number of important properties:

  • minimum compression ratio;
  • lubricating, water-repellent and anti-corrosion properties;
  • maximum boiling point;
  • the liquid should not affect rubber seals, boots and cuffs.

What kind of brake fluid was filled in from the factory?

From the factory, the conveyor is filled with DOT-4 standard fluid with the catalog name Hyundai/Kia 01100-00110 BRAKE FLUID, the manufacturer is not specified.

It is enough to know that the liquid corresponds DOT-4 standard , and the brand can be chosen at your discretion. The volume of liquid in the system is approximately 1.25 liters, therefore, for a complete replacement you need to buy at least this amount. The fluid volume including the clutch drive is 1.75 liters.

When to change?

We take a brake fluid sample using a syringe or bulb.

This move is not explained by an increase in the quality of the fluid or the reliability of the brake system, but by the price that the owner has to pay regardless of whether the car is under warranty or not.

DOT-4

Replacement is necessary after 30–40 thousand mileage.

Studies have shown that the new DOT-4 fluid has a boiling point of 264 degrees, and after a year of use in the system - only 165 degrees.

This suggests that when a critical temperature is reached, gas bubbles form in the liquid and it can no longer transmit force from the amplifier to the brake cylinders, that is, the pedal will fail with all the ensuing consequences.

In addition, the characteristics of the liquid are lost from contact with water (condensate), so replacement is still necessary after 30–40 thousand mileage . The price of liquid per liter fluctuates within a thousand rubles and this amount is not comparable to road safety.

Changing brake fluid on Hyundai Solaris correctly

We install the machine on a lift or pit for easy replacement.

To completely replace the TJ, you can use one of two technologies. The first of them requires the presence of an assistant; you can replace the fluid using the second method yourself.

Method one:

  1. We place the car on a pit or on a lift in order to provide free access to each of the wheel working cylinders.

    Placing the car on a lift to change the brake fluid.

  2. We turn off the engine and open the hood.
  3. We unscrew the cap of the expansion tank and pump out the old fuel fluid to the maximum. To do this, we use a syringe with a nozzle or a rubber bulb.

    Open the brake reservoir cap.

  4. Add new fuel oil to the tank up to the top mark.

    New brake fluid in the reservoir.

  5. We pump each wheel cylinder in this order: right rear, left front, left rear, right front.
  6. To do this, we go down under the car to the cylinder of the right rear wheel, clean the bleeder fitting from dirt, and remove the protective cap.
  7. We put a 10mm spanner on the fitting.

    We put the tube and a 10mm wrench on the fitting.

  8. We put a tube on the fitting, the second end of which is placed in a transparent vessel with a liquid container 500 ml or more.

    One end of the pipe is placed on the fitting, the other is lowered into the container.

  9. We ask your partner to press the brake pedal several times and hold it in the depressed position.
  10. Unscrew the fitting on 0.5–0.7 turns, in this case, old fuel fluid will flow from the tube into the vessel, and the pedal will fall.
  11. We continue pumping until fresh liquid begins to flow from the tube, after which we tighten the fitting. The pedal can be released.
  12. Check the fluid level in the tank, if necessary, add to the maximum.

    Check the brake fluid level in the reservoir.

  13. We move on to the left front wheel and repeat everything from the beginning, after each wheel, monitoring the level of fuel fluid in the tank so that the system does not capture air.

Second replacement method

Using the replacement technology according to the second method, you can replace the fluid yourself without outside help. However, for this you will need four hoses for fittings and four transparent containers.

The replacement process occurs as follows:

  1. Open the hood, pump out the old fluid and add new fluid to the tank to the maximum level.
  2. We provide access to all four wheel brake cylinders.
  3. We put hoses on all four fittings and lower them into the vessels.
  4. We unscrew the four bleeder fittings one by one and make sure that the old fluid begins to flow into all containers.
  5. It is imperative to check the fluid level in the tank and make sure that the system does not become airy, constantly adding fresh fluid.
  6. Each vessel should contain at least 230–250 ml of liquid; only after this can the fittings be tightened and protective caps put on.
  7. If necessary, add liquid to the maximum level.

The fluid replacement is complete, the system will now operate reliably 30-40 thousand km. Keep an eye on the brake fluid level and keep your brakes strong!

Depending on which event comes first, brake fluid replacement on Solaris is carried out every 2 years or after every 30 thousand kilometers traveled, and the price of such a procedure is absolutely affordable so that you can carry it out in a specialized center, and not on your own.

When is it necessary to change brake fluid?

In addition to the deadlines indicated by the automaker, reasons for replacing the fluid in the brake system may be found earlier. We are talking about situations when:
  • The driver of the car notices that the fluid level is dropping sharply.
  • It turns out that all the liquid has leaked out.
  • Brake fluid is available, but its quality has noticeably deteriorated during driving (when moisture gets in with air, an important physical property of the fluid is lost - a high boiling point, and therefore the effectiveness of your braking).
  • The driver was forced to mix different types of brake fluid (glycol, silicone, etc.), having no other way to get to a car service center. After this, it is imperative to drain the “cocktail” and add new liquid.

Features of replacing brake fluid on Solaris

Brake Fluid DOT4 is filled in at the Hyundai factory. DOT4 marking means the composition meets high requirements. When the time comes for replacement, it is necessary to use the same fluid, or a worthy analogue. You should not ignore the approaching replacement deadlines, as the price of such “savings” may be too high. The hygroscopicity of the liquid determines a noticeable decrease in its quality during the operation of the car. So, initially its boiling point is 265°C, after a year it is only 165°C, and after 2 years it is 100°C. This means there is a risk of the fluid boiling when braking too hard.

Where to replace brake fluid in Hyundai Solaris

The PolomokNet technical center in Moscow invites Hyundai Solaris car owners for maintenance within the framework of the regulations, and also if there is an extraordinary reason to change the brake fluid. We use special equipment, fill in high-quality and reasonably priced compounds approved by the South Korean manufacturer, which will ensure steel brake performance and long-term uninterrupted operation of the car. The cost of replacing brake fluid is 900 rubles.

Brake fluid is an essential component of absolutely any braking system. Hyundai Solaris is no exception. However, the car owner should understand that it can completely work out its entire limit and will have to be replaced with a new one. However, not every car enthusiast is ready to give money to a service center and strives to repair everything themselves. So, how is brake fluid replaced?

Required Tools

To replace you will need:

  1. A syringe or bulb for pumping brake fluid from the reservoir;
  2. Rags;
  3. Metal brush;
  4. A couple of liters of water;
  5. A thin hose that will be used to drain liquid from the fittings;
  6. Container with a volume of 300-500 ml;
  7. Brake fluid about 1 liter;
  8. Socket wrench for unscrewing fittings on brake cylinders;
  9. a partner who will help.

It is recommended to change the Hyundai Solaris brake fluid every 2 years or every 45,000 km, since it is hygroscopic and when moisture gets into it, the boiling point of the fluid decreases, and during intense braking, the system mechanisms become very hot, which can cause the brake fluid to boil and reduce the effectiveness of the brakes . Moisture also causes corrosion of the internal surfaces of the brake mechanisms, which will further lead to leakage, jamming, breakdown and replacement of these components. You can easily change the brake fluid yourself.

We recommend using the DOT 5 brand, since it meets more stringent requirements, and its price differs only slightly from DOT 4. The market is replete with different manufacturers, it’s up to you to decide which one to choose.

Step-by-step replacement instructions

  • We go to the inspection hole (if it is missing, you will have to unscrew and remove each wheel, which will take additional time).
  • Open the hood and tank lid.

  • We take a bulb or a large syringe and empty the tank.
  • Fill the reservoir with fresh fluid up to the “maximum” mark.

  • We clean the fittings on the working cylinders from dirt.

  • Take a spanner wrench and unscrew the fitting on the rear right wheel ¼-½ turn.
  • We put a hose on it and lower it into the container.
  • The assistant sits down in the car and begins to press the brake pedal repeatedly, while the old brake fluid begins to flow through the tube into the container.

  • We control the process until fresh brake fluid appears from the tube.
  • Lightly tighten the fitting with a wrench.
  • We ask your partner to press the brake pedal 2-5 times and leave it depressed.
  • Unscrew the fitting.
  • Liquid will flow out of the tube and the pedal will sink.
  • When it stops running under pressure, tighten it.
  • We repeat the pumping procedure 3-5 times.
  • Remove the hose and put on the protective cap.
  • We wipe and pour water on the dirty surfaces.
  • Add fluid to the MAX mark.
  • The brake fluid change on the right rear wheel is complete.
  • We change it in the same way on the remaining working cylinders, monitoring the level in the tank.
  • Screw on the lid and close the hood.
  • We record the mileage of the car and the date of replacement.
  • Replacement is complete.
  • Checking the brakes on the road. If efficiency has dropped, we pump the system again.

This completes the replacement. The main thing is to maintain compliance; more precisely, you need to know what kind of liquid to fill in and make sure that the limiting volume is not exceeded.

Manufacturers always write in service books about the service life of a particular fluid. The "brake" for Solaris can only last 40 thousand kilometers or, in other words, a little over two years with average use of the car. Many drivers mistakenly believe that if this substance is in a closed circuit, then nothing happens to it. But that's not true.

It is worth noting that, in fact, there are hydraulic holes in the expansion tank through which the liquid, so to speak, comes into contact with the outside world. This leads to one of the main disadvantages of such a liquid - it quite easily absorbs moisture that is in the air. The longer such contact occurs, the worse the brake system works. It was on this basis that the manufacturer calculated the operating limits, which it is not recommended to go beyond.

Brake fluid, like other lubricants, requires periodic replacement. This is due to the loss of qualities that are lost during operation. So, the process of replacing brake fluid on a Hyundai Solaris is quite simple.

Video materials

The video will tell you how to quickly and correctly change the brake fluid in a car, and also tell you about the nuances and tricks of the process.

Replacement process

The brake system on the Hyundai Solaris has two circuits; they are completely isolated from each other and are divided into parking and working. Their use in cars ensures increased driving safety. It is the responsibility of each driver to monitor their technical condition and carry out routine maintenance and change the fluid on time. We'll show you how to replace brake fluid (BF) on a Hyundai Solaris in a visual photo instruction.

We are replacing brake fluid on Hyundai Solaris. Unscrew the cap on the brake fluid reservoir.

Tools and consumables required to replace the TJ:

  • new brake fluid;
  • rags;
  • key size “10”;
  • transparent hose and container.

To quickly and successfully replace the turbocharger and bleed the brakes, it is necessary to involve an assistant, and carry out replacement actions in an inspection pit or overpass.

So, changing the fluid also involves bleeding the brake system, so let’s look at two questions at once in one topic. The sequence of actions aimed at changing the brake fluid in a Hyundai Solaris, regardless of the year of manufacture and body model:

  1. As a precaution, it is recommended to remove the negative terminal from the battery.

    Using a screwdriver, remove the mesh from the tank.

  2. Using a blower, pump out the old liquid from the tank.

    We pump out the waste liquid from the tank with a syringe.

  3. After this, pour new fluid into the reservoir and begin bleeding the brake system.

    We install the mesh in place.

  4. Since the circuits of the brake system are located diagonally, the bleeding pattern is as follows: Rear left - Front right - Rear right - Front left.

    Fill the reservoir with new, fresh fuel oil up to the MAX mark.

  5. Now, you need to clean the brake system bleeder from dirt and other unwanted objects. And then, remove the rubber protective cap of the fitting.

    We replace the fuel oil according to the diagram, starting pumping from the rear right wheel.

  6. Take a 10mm wrench and loosen the fitting.

    Remove the rubber protective cover.

  7. We put a tube on the fitting, and put the other end into a container where the old brake fluid will flow out.

    Then remove the hose and put on the protective cap.

  8. Pump the brake pedal 3-4 times at intervals of 1-2 seconds. In this case, air may escape along with the liquid. After pumping, tighten the fitting and then release it. We do this several times until the old fluid comes out of the circuit.

    Then the assistant presses the pedal 3-4 times the last time until it stops. We take the key to “10”, loosen the tightening of the fitting by ½-¾ of a turn. You should wait until the brake fluid is drained into the container. We drain the used brake fluid along with air bubbles into a previously prepared bottle. When draining, pay attention to the color and drain until clean brake fluid comes out. Thus, we pump all the wheels. Then remove the hose and put on the protective cap. Add fluid to the MAX mark.

  9. After carrying out the work, it is necessary to tighten the fitting and put on the rubber protective cap.

Fluid selection

The car manufacturer recommends using only a certified vehicle vehicle that meets all quality parameters and technical specifications. For Hyundai Solaris, DOT-3 or DOT-4 of the FMVSS116 standard is suitable. The original “BRAKE FLUID” Hyundai/Kia 0110000110 DOT 4 is filled from the factory. To fill the system you will need 0.7-0.8 liters. But if you need to completely bleed and simultaneously replace the clutch cylinder, then you just need to take a standard liter bottle.

The fuel level in the tank should be between the “MIN” and “MAX” marks marked on the side of the tank.

As the vehicle is used, the level will decrease. As for adding brake fluid to the level, there are a couple of nuances. It is forbidden to refill old fuel oil again, since it is already contaminated with impurities and filled with air and moisture.

Original Hyundai/Kia brake fluid 0110000110 DOT 4, “BRAKE FLUID”, 1l bottle, costs 1450 rubles. You can use substitutes from other manufacturers Fenox SBF4010 “SBrake”; Hella-Pagid 8DF355360021 “BRAKE FLUID”. The price will be in the range of 200-300 rubles per 1 liter.

Conclusion

On the one hand, replacing brake fluid in a Hyundai Solaris is simple, especially for those who have already carried out such a process. For a beginner, this procedure may seem quite difficult to understand, and even more so to perform, so in this case it is recommended to contact a car service.

For the safe operation of a Hyundai Solaris, the condition of the brake fluid is important. It should be changed promptly, following the manufacturer's recommendations for selection.

Carrying out the replacement will not be difficult with your own hands, but the car owner should still know some of the intricacies of the event.

The original Hyundai Brake Fluid is poured into the brake circuit of the Hyundai Solaris. It is sold under article number 0110000110. The volume of the canister is one liter, and the price ranges from 380 to 550 rubles. Branded brake fluid is classified as DOT-4.

It is allowed to fill the Hyundai Solaris brake system with fluid from third-party brands. As an alternative to the original, you can choose any technical specification that relates to DOT-4. The table below presents the best options from third-party companies that have gained wide popularity on the Hyundai Solaris.

Replacement frequency

Replacing brake fluid on Hyundai Solaris is required every 30 thousand km. At the same time, the TZ should be updated at least once every 2 years, regardless of the mileage the car has traveled.

In this case, an unscheduled replacement of the fuel tank may be required. The reasons for this are:

  • periodic boiling of brake fluid;
  • unpleasant odor that comes from the fuel tank;
  • the tester shows increased moisture content;
  • the volume of brake fluid has decreased;
  • the walls of the tank began to become covered with plaque;
  • there are flakes or other inclusions in the liquid;
  • mechanical damage to the tank body or its lid; water or other technical fluid has entered the fuel fluid.

If you do not replace the brake fluid in a timely manner, a number of negative consequences are possible. The main ones are presented below:

  • loss of the ability to stop the car due to boiling of the fuel tank;
  • corrosion of metal surfaces of the brake circuit;
  • souring of the piston in the cylinder and, as a result, the car pulling to the side when it stops;
  • dependence of braking intensity on ambient temperature.

Rules for replacing brake fluid

The fitting caps have a short lifespan. They often crack and lose elasticity. Therefore, it is advisable to have several caps in stock in order to quickly replace a worn or damaged element.

When draining the brake fluid, the correct sequence of opening the fittings should be taken into account. This will minimize the mixing of new and old fuel fluid. You can see the sequence of bleeding the brake circuit in the image below. The amount of fuel spent in this case is minimal.

Brake fluid is highly hygroscopic. Therefore, it is prohibited to use fuel oil that has been stored in an open container. The absorbed moisture significantly reduces the boiling threshold of the liquid. This increases the risk of brake failure during intense or emergency stopping of the vehicle.

The high hygroscopicity of brake fluid does not allow it to be reused after draining. For refilling, you should use only fresh fuel oil from a sealed container, for example, from a tightly closed canister.

Brake fluid contains components that make it toxic. To protect the environment, it is prohibited to discharge slurry into rivers, lakes or onto the ground. It is also not recommended to pour TJ into the sink or toilet. To ensure proper disposal, it must be taken to a toxic and hazardous waste collection point.

Brake fluid is aggressive not only to the environment, but also to the car’s paintwork. Pouring it onto the body can significantly damage the paintwork. Therefore, if TJ gets on the paintwork, it should be wiped off as soon as possible. After this, the spill area must be washed with water and car shampoo.

When changing brake fluid, avoid using rags containing lubricants. The oil reacts with the fuel fluid. As a result, the slurry loses its original properties and its use in a car significantly reduces driving safety.
