Abstract
A floating-caliper spot-type disc brake is disclosed having an arrangement for actively retracting the indirectly actuated external brake shoe to create a clearance with the brake disc. Elastic spring elements (24, 34, 38, 45) engage the external brake shoe (10) and the carrier arms (2, 3) of the brake carrier (1) and which are elastically tensioned by actuation of the brake to allow a slight retraction of the external brake shoe when the elements relax as the brake is released. The spring elements are mounted to allow a frictional grip to be overcome to shift the relative relaxed position of the spring element and external brake shoe as the brake lining wears, so that a constant disc clearance is maintained.
