Sharan car brake system has two subsystems, working independently of each other, - the working (foot) and parking. Brake system with a hydraulic drive is divided into two independent circuits: the right front and left rear wheel - one circuit, the other circuit - the left front and right rear wheel.
The pressure in both circuits braking is created in the master cylinder by pressing on the brake pedal. To reduce the effort when you press the brake pedal and a more efficient use of the system vacuum booster. Vacuum brake servo works by vacuum generated in the intake manifold petrol engine or by a special vacuum pump diesel engines. Under normal operating conditions, both circuits operate synchronously.
When one of the circuits, for example, due to its depressurization and brake fluid leaks, a second circuit operating with a loss of braking efficiency on the braking time and the braking distance. The working brake system includes a brake pedal, signals, brake master cylinder, brake servo vacuum-type disc type brakes from ATE, floating caliper at the front and rear wheels, pipes, hoses and anti-lock braking system (ABS) by Teves. When installing the ABS system to control the car removed the pressure in the brake actuator.
The parking brake is actuated via manual actuating lever Bowden cable on the brake pads in the mechanism of the rear wheels. The main brake cylinder is screwed to the front of the brake booster and serves to create a simultaneous pressure on both circuits the hydraulic brake drive when you press the brake pedal.
Above the master cylinder is expansion tank, which provides the system with brake fluid.
The front wheels of the car mounted ventilated disc brakes and rear - solid brake discs.
In a floating brake caliper pressing the brake pads to the disc by a single piston.
