Design Description

The car is equipped with two brake systems - working and parking.

The service brake system is designed to reduce the speed of the car up to its stop wave and briefly hold the car in a stationary state.

The parking brake system is designed to prevent spontaneous movement of the vehicle during parking.

The working brake system is dual-circuit, diagonal, with a hydraulic drive. Consists of a clear brake cylinder with a vacuum booster, four wheel brakes, brake lines and hoses. The brake mechanisms of the front wheels are ventilated discs, the rear brake wheels are drum or disc non-ventilated. Anti-lock braking system is installed on some cars (ABS), consisting of a valve body and wheel speed sensors. This system prevents the wheels from locking up during heavy braking by reducing the pressure in the wheel circuit, which is braked more than others.

Each of the brake circuits of the car includes the brake mechanisms of two wheels: one front and one rear, located diagonally on the car. If one of the circuits fails, the second circuit, albeit with less efficiency, will ensure the car stops.

To reduce the effort applied by the drivers to the brake pedal, a vacuum booster is installed in the brake system drive, which operates due to the vacuum formed in the inlet pipeline of the running engine.

Warning! Do not turn off the engine until the vehicle has come to a complete stop, as this will greatly increase the force that must be applied to the brake pedal to stop the vehicle.

A reservoir with brake fluid is installed on the body of the master brake cylinder. The tank has a sensor. In the event of a dangerous drop in the liquid level in the tank, the sensor turns on a warning lamp on the instrument panel.

The parking brake system has a cable drive and acts on the rear wheels. When the lever is raised on vehicles with rear drum brakes to the upper position, the levers mounted on the rear brake shoes turn and begin to put pressure on the spacer bars. At the same time, the shoes move apart and fix the brake drum from turning. When the lever is raised on vehicles with rear disc brakes to the up position, the levers mounted on the rear brake calipers rotate and push the piston out of the caliper. In this case, the pads compress and fix the brake drum from turning.
