ABSTRACT:
A disc brake assembly includes a frame which is movably disposed relative to a rotor and a central opening on the frame carries a pair of friction elements facing opposite sides of the rotor. An adjuster assembly is disposed within the central opening to control the position of the pair of friction elements relative to the rotor. The adjuster assembly includes a lever pivotally engaging the frame and an extendible assembly cooperating with the lever and frame to control the pivotal position of the lever relative to the frame. An actuator extends into the central opening and is engageable with one of the friction elements and the lever. Upon operation of the actuator, the one friction element separates from the lever to engage the rotor and the frame moves to engage the other friction element with the rotor. A pawl is responsive to movement of the actuator to control extension of the extendible assembly. The extendible assembly is carried on the lever at an end remote from the pivotal engagement with the frame. The lever carries a roller which is engageable with the actuator and a U-shaped section of the lever forms a pocket to receive the roller.
