<p>AUTOMATIC ADJUSTING DEVICE IN A DISC BRAKE An automatic adjusting device in a disc brake for adjusting a clearance between a brake disc and a friction pad. A fixed pin is axially disposed within a hydraulic cylinder, and a regulating plate frictionally fitted over, the fixed pin is connected to the piston through a return spring having a given deformation allowance. The fixed pin, the regulating plate and the return spring cooperate to automatically move the piston backward at all times in a given amount and accurately. The amount of backward movement of the piston is sufficiently obtained by selection of a predetermined deformation allowance of the return spring, thus automatically and sufficiently obtain a clearance between the brake disc and the friction pad.</p> |
