Features of the front wheel brake device

The brake mechanism is disc, with automatic adjustment of the gap between the pads and the disc, with a floating caliper. Staple 3 (pic. 120) cast from aluminum alloy together with the wheel cylinder. The movable bracket is connected by two bolts with fingers 9, which are installed in the holes of the guide 2 of the blocks. Lubricant UNIOL-1 is put into these holes. The surface of the fingers is protected by rubber covers 8. The shoe guide is tilted with two bolts to the steering knuckle. In the groove of the guide there are two brake shoes 7, which are pressed against the grooves of the guide by leaf springs 4. The springs are put on the stepped protrusions of the shoes, and their ends rest against the shelves of the grooves of the bracket 3.



A hollow piston 5 with a sealing ring 6 is installed in the cylinder cavity. Due to the elasticity of this ring and a groove of a special configuration, a certain gap between the pads and disk 1 is maintained in the cylinder. The cylinder cavity is protected by a rubber cap.
