ABSTRACT:
An improved disc brake of the type in which a rotatonal operating force is converted into a substantially linear braking force is provided with means for automatically adjusting the brake operating mechanism for normal wear of the brake pad means. The improved brake employs a housing straddling a brake disc and including a first half portion having a first friction pad secured thereto and a second half portion having a through hole; a push rod extending through the through hole and having one end abutting against a second friction pad and the other end provided with adjusting threads; a substantially cylindrical nut extending through the through hole and having at one end an enlarged diameter flange provided with ratchet teeth and at the other end a spring abutment portion, the nut having the threaded inner surface in threaded engagement with said adjusting threads of the push rod; a spring abutting at one end against the second half portion of the housing and at the other end against the spring abutment portion of the nut for normally biasing the nut away from the disc; a movement conversion mechanism provided in the second half portion of the housing and adapted to convert a rotational movement into a linear movement; and a brake lever for imparting a rotational movement to the movement conversion mechanism and a pawl member integrally secured to the brake lever for engaging the ratchet teeth.
