<p>A disc brake for an automotive vehicle is disclosed. The brake includes a stationary support member, a rotor, a pair of friction elements for brake engagement with the rotor when a brake application is effected, and a caliper slidably mounted on the support member and engaging each of the friction elements for urging them against the rotor. The torque member includes a pair of circumferentially spaced arms defining a recess therebetween, and the outer edge of one of the arms is provided with a socket which receives the pinlike element carried by the caliper so that braking torque is transmitted from the caliper to the torque member through the pinlike member and the socket during braking while the rotor is rotating in one direction. The opposite edge of the one arm, which faces into the recess, is provided with a bearing surface which cooperates with a corresponding bearing surface on the caliper so that braking torque is transmitted from the caliper to the torque through the bearing surfaces during braking while the rotor is rotating in the opposite direction. A releasable connection between the other arm of the torque member and the caliper restrains rotation of the caliper about the pinlike element. However, this connection may be manually released so that the caliper can be pivoted about the pinlike member to expose the friction elements when they require servicing.</p> |
