General information
The vehicle is equipped with two diagonal brake circuits. One circuit uses the front right and rear left wheels, the second circuit uses the front left and rear right wheels. When only one of the circuits is working, you have to press the brake pedal harder to achieve the braking of the car. This increases the pedal travel and lengthens the stopping distance.
When you press the brake pedal, the pusher presses on the two pistons of the master brake cylinder, which through the brake booster form pressure in the system.
The master brake cylinder cannot be repaired. If it fails, it must be replaced as an assembly. The pistons transmit pedal force hydraulically to the brake calipers.
The caliper pushes the wheel cylinder piston, which in turn presses the lining against the brake disc. When the pedal is released, the piston returns to its original position and the pads move away from the disc. The distance between the pads and the disc becomes about 1 mm, but this is enough for the disc to rotate freely.
