US 5,701,978 A · Set of brake pads for floating-caliper disc brake

Abstract

A set of brake pads for a floating-caliper disc brake including a first brake pad with a first retaining spring for clamping engagement on a brake piston and a second brake pad with a second retaining spring for clamping engagement on an axially external leg of the floating caliper. The first retaining spring has two resilient tongues which are locked in a bore of the hollow brake piston, and the second retaining spring has identical resilient tongues which are locked in a recess of the external housing leg. According to the present invention, the distances between the respectively opposed resilient tongues are different in conformity with the different widths of the bore and the recess, respectively. The provision according to the present invention renders it impossible to attach the first brake pad to the external housing leg and the second brake pad to the brake piston. This safeguard against a mix-up is especially advantageous when the first friction lining of the first brake pad differs in shape from the second friction lining of the second brake pad so that the two brake pads must under no circumstances get mixed up.

A set of brake pads for a floating-caliper disc brake, comprising:

a first brake pad used for abutment on a brake piston on the axially inner side of a floating caliper, the first brake pad including a backplate which carries a first friction lining and has attached to its rear side a first retaining spring for clamping engagement of the first brake pad on the brake piston, and
a second brake pad used for abutment on an external housing leg of the floating caliper, the second brake pad including a backplate which carries a second friction lining and has attached to its rear side a second retaining spring for clamping engagement of the second brake pad on a recess of the external housing leg, wherein the first and second retaining springs respectively include opposed resilient tongues, wherein said first friction lining and said second friction lining are different in shape, and wherein the distance between two opposed resilient tongues of the first retaining spring is different from the distance between two opposed resilient tongues of the second retaining spring, to thereby safeguard said first brake pad against clamping engagement on said recess of the external housing leg and said second brake pad against clamping engagement on said brake piston.
