The service brake system ensures the regulation of the vehicle speed and its stopping with the required efficiency. The spare brake system serves to stop the vehicle with the required efficiency when the service brake system fails.
The parking brake is used to hold the car motionless relative to the road. It is mainly used to hold a parked car, but it can also be used as an emergency brake if the working brake system fails.
The vehicle uses a hydraulically driven service brake system with diagonally separated circuits, which significantly increases the safety of driving the vehicle. If one of the circuits fails, the second circuit is used as a backup brake system, ensuring that the vehicle stops with sufficient efficiency.
The braking system consists of a master cylinder, a vacuum brake booster, disc brakes on the front wheels and drum or disc brakes on the rear wheels.
The vacuum brake booster reduces the force of the brake pedal, thereby making the car easier to control.
The rear brake pressure regulator is located in the hydraulic drive for each rear brake. On most models, the pressure regulators are located separately, but on some models with rear brake drums, the pressure regulators are combined with the rear working cylinders.
On vehicles with diesel engines, a separate vacuum pump is used to create the vacuum that powers the brake booster. It is mounted on the end of the cylinder head and is driven directly by the camshaft.
When driving on a wet road, it is recommended to press the brake pedal from time to time to remove harmful inclusions from the brake discs. Due to centrifugal force, water is thrown off the brake discs during movement, but a thin film of fats, silicones, rubber residues, grease and dirt remains on them, which reduce the effectiveness of braking.
After installing new brake pads, they must be worked in. During the first 200-300 km of mileage, it is not recommended to perform maximum braking unless necessary.
Corroded brake discs cause a vibration effect during braking, which does not disappear during prolonged braking. In this case, the brake discs must be replaced.
