Abstract

The invention relates to a spot-type disc brake, in particular for automotive vehicles, with two brake carrier arms being positioned at a distance from each other in the direction of a secant in respect of the brake disc, with two brake shoes resting radially on the brake carrier arms, with a brake housing which straddles the brake shoes and the brake disc in a U-shaped manner, with a piston-and-cylinder unit being positioned within a first, internal stem of the housing and by means of which the first brake shoe allows to be urged directly against a first side of the brake disc, and with a second, external stem being coupled to the first stem through a bridge section and urging the second, external brake shoe indirectly against the other side of the brake disc. According to the invention, the external stem has a continuous and uninterrupted bearing surface which bears against the second, external brake shoe resulting in a closed design of the external stem. A closed design is one where there is no gap in the radial direction of the second external stem. A closed design is achieved by configuring the second external stem with a radially innermost edge which extends in a substantially circumferential direction along its entire length. The disc brake may include external ribs for cooling or for stability. The disc brake has tangential ends which are coupled to brake carrier arms.
