Abstract
The brake assembly (10, 110, 210) comprises a caliper housing (14, 114, 214) having a bore (26, 226) with a first piston (30, 230) slidably received therein. The first piston (30, 230) includes a recess (34, 234) receiving the head (52, 252) of a longitudinally extending rod (50, 250), the head (52) displaced from a surface (35) of the recess (34) by a resilient mechanism (37). The piston (30, 230) has a first seal (40, 240) disposed thereabout. The longitudinally extending rod (50) has an end (54) with a second seal (60) disposed thereabout, the end (54) received slidably within a tube (70) having a flange (72). The flange (72) of the tube (70) has a first spring (80, 180) located thereabout, the first spring (80, 180) biasing tube (70) away from a second piston (90) positioned about the tube (70) and rod (50 ). A retainer (110) is mounted fixedly within the bore (26) and extends longitudinally within an enlarged opening portion (32) of the first piston (30) to provide an abutment for a second spring (100) which biases the second piston (90) away from the first piston (30). The brake assembly (10, 110) provides the combination of an automatic pressure compensated adjustment, positive piston retraction, and piston knock-back control. Alternatively, the brake assembly (210) may include positive piston retraction and piston knock-back control by having a second rod (270) received within an opening (254) of the first rod (250), the resilient mechanism (237) located between the flange (272) and a caliper housing wall (245), and a spring (280) for piston retraction disposed between the flange (272) and an extension (219) of the caliper housing (214).
