ABSTRACT:
A disc brake assembly includes a rotor and a pair of friction elements which are engageable with the rotor to retard rotation of the latter. A support carries the rotor and movably disposes the pair of friction elements adjacent the rotor. An actuator is pivotally mounted on the support and is provided with a cam member to urge the pair of friction elements into engagement with the rotor as the actuator moves from a neutral position to a braking position. The actuator includes at least one friction pad which is engageable with the rotor to move the actuator from the neutral position to the braking position. An input member on the actuator is operated by a vehicle operator to control the engagement of the one friction pad with the rotor. The actuator rotates about its pivotal mounting on the support and in the direction of rotation of the rotor when it moves from the neutral position to the braking position. A frame includes a central opening for carrying the pair of friction elements and an extendible assembly is carried within the central opening by a lever. The lever is adjustable by the extendible assembly to control the position of the pair of friction elements relative to the rotor.
