For spare parts uaz apply the brakes. uaz is working. Parking and emergency braking system. Brake system with drum brake mechanisms on the front and rear wheels. On two separate hydraulic drive them from the two chamber master cylinder: one-to-Front wheel brake, the other – to the Rear wheel brake. Also to the braking system and include the following parts UAZ: parking braking system, a spare brake systems. Spare brake system is each circuit hydraulic drive.
Parking brake system with drum brake mechanism located behind the transfer frame and acting on the rear driveshaft has a manual mechanical drive. The front brakes have two wheel cylinders, each of which separately operates on the block. Rear brakes have one wheeled cylinder, acting on both blocks. The main thing in these spare parts uaz proper installation pad. Pads inner surface of its rim are based on adjusting eccentrics, adjustably mounted on the brake shield. From arbitrary turning eccentrics are held by strong springs. Pads are pressed against the cam return spring. hex head bolt adjustment cams displayed on the outer strontium brake shield.
With the help of cams installed the necessary clearance between the pads and the drum. Of lateral displacement of the pads are held in vyshtampovkami shield and springs installed in the middle of the pads. Wheel cylinder has two openings. One hole is for the supply of brake fluid from the system drive, and another – to release the air from the system by pumping: it is closed bypass valve. Which in wrapped state provides tightness. To protect it from clogging the valve opening is closed screw cap. Internal cavities wheel cylinders are protected from moisture, dust and dirt with rubber caps. Brakes various brands uaz different shields. The same brake drums on all wheels on a car these parts uaz (drums) are attached to the hub with three screws, which are unevenly around the circumference, it is provides installation of a drum on the hub in a certain position when the processed drum assembly with the hub. Swap brake drums on one hub to another is not recommended, as this will to increase the working surfaces of the drum beats.
