Warning: Brake fluid can damage your eyes and body paint, so be careful when working on the brake system. Do not use fluid that has been stored in an open container for a long time, because brake fluid is hygroscopic and absorbs moisture from the air. Excess moisture in the brake fluid can significantly reduce the effectiveness of the brakes.
1. The steps are the same as those described in Chapter 9 for bleeding the brake system, with the only difference being that the reservoir must be cleaned before starting. Please note that the steps are different for vehicles equipped with ABS / ASR systems. When pumping a section of the brake system, the old brake fluid should be allowed to flow out.
2. Proceed as described in chapter 9, first unscrew the first air release valve and gently pump the brake pedal until almost all of the old fluid has flowed out of the master cylinder reservoir.
3. Add new fluid to the mark "MAX", and continue pumping the pedal until only new fluid remains in the reservoir and new fluid appears from under the screw. Close the valve and add fluid to the mark "MAX" on the tank.
4. Do the same for all valves in the system in sequence. Maintain the fluid level in the master cylinder reservoir at or below the mark "MIN" If this is not done, then air can enter the system and this will significantly increase the duration of the operation.
Advice. The color of the old fluid is slightly darker than the new one. This circumstance makes it easy to distinguish the liquid.
5. After completing the operation, check that all valves are screwed on and dust caps are on. Remove all traces of fluid leaks and check the fluid level in the brake master cylinder reservoir.
6. Before leaving the car on the road, check the operation of the brakes.
