Warning! Remember that brake fluid is a chemically aggressive substance and requires special care in handling. Do not allow brake fluid to come into contact with your eyes, exposed skin, or painted surfaces of the vehicle. In addition to being toxic, brake fluid is also highly hygroscopic (i.e., has the ability to accumulate moisture from the air). Excessive moisture in the fluid leads to a dangerous decrease in the efficiency of the brake system. Use only fresh brake fluid, do not leave it in a loosely closed container for a long time.
1. Brake fluid should be changed regularly and in strict accordance with the vehicle's routine maintenance schedule. Prepare a sufficient amount of clean rags or paper towels in advance to collect any spilled fluid. To protect adjacent painted body panels, place rags around the brake master cylinder.
2. Prepare replacement brake fluid of the required grade (see Specifications at the beginning of the Chapter).
3. Remove the cap from the brake master cylinder reservoir.
4. Using a hand pump, syringe or rubber bulb, pump out the liquid present in the cylinder.
5. Fill the reservoir with fresh brake fluid, bringing its level to the lower edge of the filler neck.
6. Monitoring the fluid level in the reservoir, bleed all four brake mechanisms one by one (see Chapter Brake system), achieving the beginning of the release of fresh liquid from the valves.
7. Check the fluid level in the master cylinder reservoir again, and make the appropriate adjustments if necessary. The foot brake pedal should be pressed with firm resistance - a feeling of softness is unacceptable.
Attention! Never start operating the vehicle without being absolutely sure that the brakes are functioning properly!
