Abstract
Abstract A brake shoe support for a spot-type disc brake having a caliper embracing the brake disc. The caliper supports the brake shoe remote from the brake actuation device. The brake shoe includes a projection which is disposed in a supporting bore in the caliper and is held in position by a bolt having a radial groove which is engaged by a retaining spring secured to the caliper. The brake shoe also includes a brake pad carrier plate and a brake pad with the brake pad having a first portion parallel to the brake disc and a second portion perpendicular to the brake disc extending over the edge of the brake pad carrier plate. The second portion abuts a supporting surface provided in the caliper adjacent the end of the supporting bore adjacent the brake pad carrier plate to prevent twisting of the brake shoe.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
246 words
An arrangement to support a brake shoe of a spot-type disc brake comprising: a housing having a longitudinal axis; an actuation device disposed in said housing coaxial of said axis; a caliper connected to said housing and embracing a brake disc; a first brake shoe connected to said actuation device and perpendicular to said axis; a second brake shoe perpendicular to said axis and associated with said caliper remote from said actuation device, said second brake shoe including a brake pad carrier plate and brake pad, said brake pad having a first portion perpendicular to said axis and a second portion parallel to said axis extending over the outer edge of said carrier plate; a supporting bore disposed coaxial of said axis in said caliper remote from said actuation device; at least a first projection extending from and integral with said carrier plate in engagement with said supporting bore; a supporting surface provided in said caliper remote from said actuation device at the end of said supporting bore adjacent said carrier plate, said supporting surface abutting said second portion of said brake pad to prevent twisting of said second brake shoe; a supporting bolt secured to said carrier plate coaxial of said axis and extending into said supporting bore; and a retaining spring secured to said caliper extending into said supporting bore and fastened to said supporting bolt. a retaining spring secured to said caliper extending into said supporting bore and fastened to said supporting bolt.
