At the service station, the system is pumped under pressure using a special device. When performing work independently, it is necessary to carry it out especially carefully. Under no circumstances should you drive a car with faulty brakes.
Before starting work, remove dirt from all bleed nipples and from the tank cap. If preliminary work was carried out only on one caliper, it will be sufficient to bleed only the affected brake circuit, i.e. the rear and front mechanisms. The general bleeding order recommended by the manufacturer is: rear right wheel, front left, rear left, front right. Bleeding the brakes is carried out in the following order:
- place one end of the transparent hose onto the bleed nipple, removing the plug from it. Place the other end of the hose in a glass container with a small amount of brake fluid;
Figure 301. Bleeding the brakes
- the assistant should press the brake pedal all the way down several times and hold it there. Loosen the fitting bolt by half a turn (figure 301), the pedal will drop slightly. Visually inspect the brake fluid leaking through the hose;
- if it no longer contains air bubbles, stop bleeding. When you press the pedal for the last time, hold it down and then tighten the fitting bolt. Then slowly release the pedal.
Carry out the same operation on all bleed nipples.
Attention! During bleeding, it is necessary to monitor the fluid level in the tank to prevent air from entering the system. Never pour brake fluid that has leaked out during bleeding back into the reservoir. Do not use liquid that has been stored in an unsealed container for a long time.
