The parking brake acts on the rear wheels. His driving lever is located between the front seats. The lever is provided with a ratchet, which is released by pressing on the lever. From the rocker arm through to each wheel is a rope. When lifting the hand lever (hand) is moved relative to the brake cable braid, resting on the bracket 9 and the lever 8 rotates about the axis of shaft 7, on the other end of which is located a plate 6 with three tapered slots of varying depth. Each nest is ball 11. Together with the ring 10, these parts form a mechanism that causes the shaft rotates shaft 7 to move axially. Tapered slot arranged so that the initially large, with respect to the rotational axial movement becomes small (in a way loses - gains in force). This increases the force transmitted. The axial movement of the shaft 7 is transmitted to the screw head 5, which is compressing the spring 12 through the nut 4 transmits power piston 3 is mounted in a floating caliper 13, and together with the bracket, through the brake pads 2 pinches the brake disc 1. The effect of self-parking brake It occurs due to the fact that at least a pair of wear "master-brake disk" will appear, and an enlarged clearance, without encountering resistance, the shaft 7 cranks screw 5 relative to the nut 4, which reduces the clearance between the brake pads and the disc. A pair of "screw-nut" (Pos. 5 and 4) has a backlash in the threaded joint, which allows the braking mechanism to release the brake disc when
the parking brake is not engaged.
