Replacing brake fluid (VAZ-2109)

To prevent air from entering the hydraulic drive system and to spend a minimum amount of time on this operation, you must adhere to the following rules:

• proceed in the same order as when bleeding the brakes, but use a hose with a glass tube at the end, which is lowered into a container with brake fluid;
• press and release the brake pedal, pumping out the old fluid until fresh fluid appears in the tube; then perform two more full strokes of the brake pedal and, holding it in the pressed position, tighten the nipple. When bleeding, monitor the fluid level in the tank and promptly top up the fluid to the maximum level;
• repeat the same operation on each working cylinder in the same order as when bleeding;
• fill the tank to the maximum level and check the operation of the brakes while the vehicle is moving.
