DISC BRAKE OF THE FLOATING TYPE

摘要

This is a disc brake of the floating type particularly adapted for use with motor vehicles. The brake has a fixed member disposed on one side of a rotating disc and having two outwardly extending circumferentially spaced arms, each arm having a pin extending away from the disc in the direction of the axis of rotation of the disc. A floating member straddles the disc, and includes a pair of mutually opposed friction members for engaging the disc and an actuator therefor. The floating member further has a pair of bores for engaging the pins such that the floating member is slidable on the pins. The fixed member is provided with a shoulder engaging one of the friction members for receiving the braking torque therefrom, and the braking torque from the other of the friction members is received by the floating member and is passed to the fixed member through one of the pins. There is a predetermined clearance between each of the bores and its associated pin, and the pin that receives the torque from such other friction member has less clearance with its bore than the other pin.
