ABSTRACT:
A disk brake comprises a caliper housing adapted to fit over the edge of a brake disk rotatable about an axis, a pair of brakeshoes in the housing axially flanking the disk and each having a brake pad turned toward the respective face of the disk and a backing plate turned away therefrom, and an actuator in the housing and engaging the backing plates for urging the brakeshoes together against the disk. The backing plates are formed with respective axially throughgoing brakeshoe passages and the housing is formed with respective housing passages in line with the brakeshoe passages. The brake further has a spring compressed axially between the brakeshoes and having respective legs extending toward the shoes, respective pusher portions extending from the legs and lying flatly against the backing plates, and respective guide portions extending from the pusher portions and extending axially through the respective brakeshoe passage and housing passage. The pusher portions urge the brakeshoes axially apart and the guide portions guide the brakeshoes in the housing.
