1. A disc brake operable to apply a clamping force to a rotatable disc, the disc brake comprising:
- a support bracket;
slide pins coupled to said support bracket;
inner and outer brake shoes; and
a caliper slidably supported by the slide pins, the caliper having first and second spaced apart piston cavities positioned along a longitudinally extending rail, a plurality of spaced apart fingers positioned opposite said rail and a laterally extending bridge interconnecting said rail and said fingers, said bridge including four spaced apart and substantially parallel bridge portions.

Abstract
A disc brake includes a support bracket, slide pins coupled to the support bracket, inner and outer brake shoes and a caliper moveably supported by the slide pins. The caliper has first and second spaced apart piston cavities positioned along a longitudinally extending rail, a plurality of spaced apart fingers positioned opposite the rail and a laterally extending bridge interconnecting the rail and the fingers. The bridge includes spaced apart and substantially parallel bridge portions. The rail includes a recess extending from a side of the rail including openings to the piston cavities.

22. A disc brake comprising:
-
a rotatable disc;
a support bracket;
slide pins coupled to the support bracket, each slide pin extending along a pin axis aligned to intersect the disc;
inner and outer brake shoes; and
a caliper slidably supported by the slide pins, the caliper slidably supporting two pistons operable to cause the inner and outer brake shoes to move toward the rotatable disc, the caliper including a rail having cavities in receipt of said pistons and a recess positioned between said piston cavities. - View Dependent Claims (23, 24, 25, 26)
