Attention! Brake fluid can harm you if it gets in your eyes, and it can harm your car if it comes into contact with painted surfaces. Do not use brake fluid that has been in an open container for some time or is more than a year old. Brake fluid is highly hygroscopic - it absorbs moisture from the atmosphere. Excess moisture in the fluid can lead to loss of brake performance.
1. Brake fluid should be changed according to the service schedule. Take precautions to prevent liquid from getting on the painted surfaces of the body - surround the brake master cylinder with a sufficient amount of rags.
2. Before starting work, stock up on a sufficient amount of fresh brake fluid of the recommended type (see Recommended Oils and Fluids at the beginning of this chapter).
3. Remove the cap from the brake fluid reservoir on the master cylinder.
4. Using a hand pump, syringe, or other similar tool, pump fluid out of the reservoir.
5. Fill the reservoir with fresh brake fluid up to the base of the filler neck
6. Bleed the brake system, as described in chapter 9, on all four wheels until new fluid flows out of the nipples without signs of contamination. Maintain the level of brake fluid in the reservoir while bleeding to prevent air from entering the brake cylinder.
7. At the end of work, add liquid to the tank to the required level and check the operation of the brakes. The pedal, when pressed, should experience a hard stop without any compliance.
Warning! Do not travel by car if you have even the slightest doubt about the reliability of the brakes.
