Abstract

A brake caliper formed without machining for a spot-type disc brake, in which the brake caliper after subsequent machining forms a floating caliper, has a braking force generator (12) and an opposite-lying abutment (22). For the non-machining forming of the brake caliper (10) two mould parts (34, 36) each partially receiving the brake caliper (10) are used, in which support surfaces (Q1, Q2, Q3, Q4, Q5) and action surfaces (S1/2, S3, S4, S5) are formed on the brake caliper (10) in such a way that the brake caliper (10) for the subsequent machining is supportable by its support surfaces (Q1, Q2, Q3, Q4, Q5) in a defined manner and clampable by means of clamping forces acting upon its action surfaces (S1/2, S3, S4, S5). To keep the extent of the subsequent machining to a minimum, during the non-machining forming the abutment (22) and the support surfaces (Q1, Q2, Q3, Q4, Q5) of the brake caliper (10) are formed in one and the same mould part (34).
