Disc brake with positively actuated pads

摘要

A disc brake has a rotary disc; a pair of friction pads disposed on the opposite sides of the disc applying frictional force to the disc and a body having a first or center cylinder for receiving a center piston acting on one of the pads, at least one second or side cylinder disposed radially and outwardly of the center cylinder for receiving a second piston; a beam acting on the other pad, and a rod for transmitting the movement of the second piston to the beam, whereby when the disc brake is actuated, the first and second pistons move in the opposite directions to cause the pads to be applied against the disc.
