Abstract
The invention provides a disc brake for parking a vehicle, wherein a reset spring is reliably positioned between a parking rod and the main body of a braking caliper so as to be prevented from shaking and the like. Meanwhile, the reset spring is stable in load and is prevented from interfering with a braking cable. The parking rod (3) is connected with the braking cable (4). When the braking cable (4) is drawn, the braking for parking a vehicle is realized by an adjusting blot (5). Meanwhile, after the parking is released, the parking rod (3) is reset under the action of the resetting force of the reset spring compressed between the parking rod (3) and the main body of the braking caliper (1). In this way, the clamping force exerted a disc rotor (10) by friction pads (7, 8) is released by means of the adjusting blot (5). One end of the reset spring (6) abuts against the parking rod (3), while the other end of the reset spring (6) abuts against the main body of the braking caliper (1).
