Braking mechanisms. The task of the braking mechanism is to create the braking force of the car on the basis of friction. In terms of their construction, the brake mechanisms are divided into drum brakes, band and disc. The drum brake mechanism is foldable: from a brake drum attached to the wheel hub and rotating with it while driving; fixed brake disc, rigidly attached to the flange of the rear axle shaft or to the steering knuckle; brake shoes z (glued or riveted friction linings, made of plastic, with high coefficient of friction and abrasion resistant; from a mechanical expander rotatably mounted on the disc, with an elliptical shape connected to the brake rod and adjusting devices, which include eccentric thrust pins and adjustment eccentrics, which are used to set the appropriate clearance (usually 0,25-0,4 Mm) between the friction lining of the shoe and the working surface of the brake drum. Due to the rotation of the eccentrics, the jaws are moved closer to or away from the working surface of the brake drum. The adjustment heads of the eccentric thrust pins are located on the outer side of the brake disc. Adjustment by means of thrust pins guarantees correct contact of the shoe with the brake drum along its entire length.
