Abstract
An automatic clearance adjusting mechanism is provided for brake in which a piston fitted in an actuator for urging a friction pad onto a rotor member. The piston is retained at a predetermined position in the actuator by a frictional force, and is allowed to axially move a predetermined distance from the retained position against an elastic force. The mechanism includes friction giving ring such as an elastic seal ring for restoring the piston to its original position, by taking advantage of the pressure within the actuator, when the same has been forcibly displaced from the predetermined position due to the elasticity deflection of brake component parts in the event of an unusual pressure rising within the wheel cylinder beyond a predetermined limit.
