ABSTRACT:
A disk brake assembly for a trailer includes a rotor, inner and outer brake pads, a mounting bracket, upper and lower pad retention assemblies, a caliper assembly and a clamping arm. The rotor is a disk having the inner and outer brake pads positioned on opposite sides thereof. The mounting bracket, in cooperation with the upper and lower pad retention assemblies, maintains the position of the inner and outer brake pads relative to the rotor. The mounting bracket has a body with an upper arm and a lower arm extending therefrom. The upper arm has a downwardly-facing guide surface and the lower arm has an upwardly-facing guide surface. Each pad retention assembly includes an engagement sleeve, a clamping arm coupling and a pair of "U"-shaped spring sections connecting the engagement sleeve and clamping arm coupling. The upper engagement sleeve is mounted on the guide surface of the upper arm and the lower engagement sleeve is mounted on the guide surface of the lower arm. Each brake pad has an upper groove and a lower groove slidingly received by the upper and lower engagement sleeves, respectively. The caliper assembly is mounted on the mounting bracket and houses an actuatable piston adjacent the inner brake pad. The clamping arm is a flexibly configured structure connected to the caliper assembly. The clamping arm biases the outer brake pad inwardly against the outer side of the rotor when the actuated piston biases the inner brake pad against the inner side of the rotor. Flexure of the clamping arm desirably dampens pressure spikes generated by the brake actuator of the trailer and delivered to the caliper assembly.
