The brake systems of a car are designed to reduce the speed of its movement with the desired intensity up to a stop, maintain a constant speed on the slopes and hold it in the parking lot. In accordance with the characteristic modes of braking, a passenger car must have a working, parking and spare system.
Each system consists of brake mechanisms (brakes) and brake drive.
Brakes are designed to create and modify artificial rolling resistance.
The brake actuator is used to actuate the brake mechanisms. It either transmits the force generated by the driver to the brake mechanisms, or controls an external source of energy needed to actuate the brake mechanisms.
The car is equipped with a working brake system, consisting of wheel friction mechanisms and a double-circuit hydraulic brake drive with a vacuum booster. The vehicle is fitted with an anti-lock braking system (ABS) brakes. The brake mechanisms of the front and rear wheels are disc.
The hydraulic brake drive ensures that the force created by the driver on the brake pedals is transmitted to the brake mechanisms through the working fluid (brake), with which it is filled. The hydraulic drive of the car is divided into two independent circuits in a diagonal pattern: one circuit actuates the brake mechanisms of the front right and rear left, the other - the front left and rear right wheels.
The hydraulic brake fluid is DOT 3, DOT 4 or DOT 5. DOT 5 is purple.
