ABSTRACT:
A mechanically operated disc brake of the type including a caliper slidably supported in the axial direction of a disc and straddling a peripheral portion of the disc, a pair of friction pads one of which is urged against the disc by a limb of the caliper, a cavity formed in another limb of the caliper, a nut member mounted in the cavity and being adapted to receive a rotational input force, a converting mechanism received in the cavity for converting the rotational movement of the nut member into axial movement thereof, a rod member screw-threadingly engaging with the nut member with the inner end abutting with the other friction pad for urging the same against the disc, and a rotation control member for controlling rotation of the nut member. The cavity of the caliper has an inner cavity receiving therein the nut member and the converting mechanism, and an outer cavity partitioned from the inner cavity by an annular wall and receiving therein the rotation control member and a return spring which acts on the outer end of the rod member for biassing the rod member outwardly.
