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.

After pumping out the old brake fluid, pour new brake fluid into the reservoir.
We carry out the replacement with the engine not running, first in one circuit, and then in the other in the following sequence:
- brake mechanism of the right rear wheel.
- brake mechanism of the left front wheel.
- left rear wheel brake.
- brake mechanism of the right front wheel.
We clean the bleeder fitting of the brake mechanism of the right rear wheel from dirt.

The nominal volume of the internal channels of the cooling system is 5.3 liters. Since the drain is done only from the radiator part and the expansion tank, coolant remains in the engine and heater radiator. Therefore, the amount of water is about 4 liters.
When changing the composition, an air lock may be created. If it has formed, and when the engine warms up, this will be indicated by the flow of cool air from the interior heating system, then you should stop the internal combustion engine and let it cool. After. Remove the radiator cap and start the engine for a couple of minutes. the air will come out.

Remove the protective cap from the brake bleeder fitting.
Use a spanner wrench or a 10mm socket to loosen the bleeder fitting. We put a hose on the fitting, and immerse its free end in a container partially filled with working fluid.
An assistant should vigorously press the brake pedal all the way 4-5 times and keep it pressed.
DOT Fluid Classification
The technical documentation of any car directly indicates which standard fluids can be used for this car. You cannot deviate from the requirements. Mixing some liquids, but not all (.) Allowed, but not recommended. Description of standards according to DOT:
- DOT 3. This is an older class that can still be found on sale. The waters are made on a glycol base. In accordance with the standard, the boiling point of “dry” (without water) water is at least 205 ° C. And “wet” (3.5% water). more than 140 ° C. The period for changing water of this class is two years.
- DOT 4. Similarly, they have a glycol base, but their composition is improved by the introduction of additional additives created to improve lubricating parameters and protect against corrosion. In accordance with the standard, the boiling point of “dry” DOT 4 water is at least 230 ° C, and “wet” water. more than 155 ° C. Viscosity requirements are also evenly limited. 750 1800 mm 2 / s.
- DOT 4.5, DOT 4, DOT 4 SUPER, DOT 6. These are subclasses. faster, a promotional ploy by SELECTED manufacturers who add additional additive packages to standard DOT 4 waters to improve their features. There is no single requirement here, but in any case, they should not be worse than DOT 4 waters, and from time to time slightly superior to them.
- DOT 5.1. This liquid is a technological continuation of the DOT 4 class, namely, in terms of expanding the temperature spectrum and protective qualities. Such brake waters are also made on the basis of glycols. But they have a significant flaw. they are very hygroscopic. And taking into account their high cost, they did not find adequate popularity.
- DOT 5. Class of brake fluids. Closer to Impeccable characteristics, since their base is made on the basis of silicones. Accordingly, they are one hundred percent NOT hygroscopic (do not absorb water), have a very wide temperature range (according to the standard, the boiling point of “dry” water is 260 ° C, and “wet” water is 180 ° C), and the replacement period is increased to 5 years . The introduction of such water is permissible only according to the requirements of the automaker, because there are a number of operational features

Pros and cons of brake fluids
All the brake waters mentioned above have their pros and cons. For convenience, we indicate them in the table below:

Using a 10mm wrench, unscrew the bleeder fitting 1/2–3/4 turn.
In this case, liquid with air bubbles will flow out of the hose, and the brake pedal will move forward.
As soon as the liquid stops flowing out of the hose (the pedal should go all the way), tighten the fitting, and only after that can the assistant release the pedal.
We repeat pumping until the liquid coming out of the hose becomes light-colored. We remove the hose, wipe the bleeder fitting dry and put a protective cap on it.
Pointed question: what happens if you mix antifreeze of different brands and colors and the consequences
Before adding anything to the expansion tank, you should once again ask what brand of coolant is filled. After all, by mixing mixtures prepared on different bases, you can simply clog the channels of the engine cooling jacket.
Since the manual correctly states that the composition should be ethylene glycol, the product can only be topped up on this base. It is allowed to diversify by manufacturers and brands. under no circumstances.

What happens if you connect? Everything is quite basic. Corrosion inhibitors are of different types; with their assistance, sediment or flakes may be released.
Many motorists struggle with the question: what if you mix antifreeze of different colors and what will happen after that? The answer is simple. nothing, as long as the base is the same. Generally speaking, there are standards for colors. Different companies use different pigments.
For your information. In the absence of Antifreeze, small additions into the Solaris expansion tank will completely drain distilled water (within the range of 100-500 ml).
2272-6-12-02-03
We pump, as described above, the brake mechanism of the left front wheel.
Similarly, we bleed the brake mechanisms of the other circuit.
When pumping, you need to monitor the fluid level in the tank and add fluid.
We pump the hydraulic drive of the brake system until new fluid (lighter than the old) begins to come out of the bleeding fittings of all working cylinders. After pumping, bring the fluid level in the hydraulic brake reservoir to normal.
There is an even simpler option for replacing brake fluid. This method does not require the presence of an assistant. With this method, a certain supply of brake fluid is desirable (at least 1 liter).
We place the car on an inspection ditch or overpass and ensure free movement between the brake fluid reservoir in the engine compartment and the brake cylinders of all four wheels.
Use a rubber bulb or syringe to pump out the brake fluid from the reservoir. Add new fluid to the top edge. To speed up the process (to release fluid from all cylinders at once), it is advisable to select four pieces of tubes that fit tightly onto the bleeder fittings of all cylinders. We lower the free ends of the tubes into small transparent bottles.
We unscrew the fittings of all brake cylinders. We make sure that the liquid has flowed through all four tubes. We control the decrease in fluid from the reservoir located on the brake cylinder and immediately replenish the reservoir. We observe an increase in the level of liquid in bottles located near the wheel brake cylinders.
It is necessary to move several times from the position of observing the flow of fluid from the brake cylinder fittings to a position where you can check and replenish the fluid level in the reservoir located on the brake cylinder in order to prevent the reservoir from drying out.
Usually the level rises most quickly in the bottle into which the hose coming from the brake cylinder of the front left wheel is lowered. As soon as there is about 200 ml of liquid in the bottle of the front left wheel, wrap and tighten the fitting of this cylinder. Next, we wait for the same result for the front right wheel cylinder, and tighten its bleeder fitting in the same way. The process can be completed after 200–250 ml of liquid comes out through the fitting of each rear wheel.
We make sure that all fittings are tightly tightened. We put on protective caps. Check the fluid level in the master cylinder reservoir.

Replacing the working fluid in the hydraulic brake system of Hyundai Solaris
Regulations for replacing brake fluid on Hyundai Solaris
Only recommended consumables should be used.
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?
Brake Fluid packaging.
Packaging, front view.
Packaging, rear view.
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 complies with the DOT-4 standard , and you can choose the brand 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.
Previously, the manufacturer recommended replacing the fluid after every 30 thousand kilometers or after two years of operation, but today the replacement can be carried out at the discretion of the owner.
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.
Finding out what antifreeze to pour into the Hyundai Solaris sedan: suitable options
When trying to find out what kind of antifreeze to fill in the Hyundai Solaris, you should contact the operation management. It correctly states that you can only pour Antifreeze diluted with distilled water. With all this, the coolant should be based on ethylene glycol and completely adaptable to an alloy radiator. Depending on the year of manufacture and place of assembly, the chemical composition of the solution varies:
For your information. Green pigment has been added to the waters listed.
The manufacturer filled the first Solaris models with Shell GlycoShell Longlife or Shell Premium Antifreeze coolant.
Briefly about the main thing
For anyone who is interested in what kind of antifreeze to pour into a Hyundai Solaris car, the advice is as follows:
- Hyundai Long Life Coolant (concentrate).
- Crown LLC A-110 / Coolstream A-110.
- Shell GlycoShell Longlife or Shell Premium Antifreeze.
In general, the plant suggests pouring in mixtures only based on ethylene glycol. According to WAG specification. this is G11.
Combining compositions of different colors is allowed. It is also allowed to combine formulations from different manufacturers. It is forbidden to mix cooling waters of different bases, in other words brands.
