Abstract:
1. A method of effecting the non-machining forming of a brake caliper blank for a spot-type disc brake, in which the brake caliper blank after subsequent machining forms a floating caliper, comprising: a braking force generator in the form of a cylinder, which defines a cylinder axis and has a cylinder bottom, an abutment lying opposite the braking force generator, at least one pair of guide bodies, which are formed one on either side of the cylinder, and on each of which a guide having a guide axis parallel to the cylinder axis may be formed, and a bridge, which connects the braking force generator to the abutment and has an inner side facing the cylinder axis, wherein for the non-machining forming at least two mould parts each partially moulding the brake caliper blank are used, in which as preparation for subsequent machining support surfaces and action surfaces are formed on the brake caliper blank, wherein the brake caliper blank for the subsequent machining is supportable by its support surfaces in a defined manner and clampable by means of clamping forces acting upon its action surfaces, wherein during the non-machining forming of the brake caliper blank the abutment and the support surfaces of the brake caliper blank are formed in one and the same mould part, a first support surface and a second support surface are formed on the inner side of the bridge at identical distances from the cylinder axis, each adjacent to one of the two guide axes, close to the abutment, and a third support surface is formed in an edge region of the cylinder bottom remote from the bridge in such a way as to be centered in relation to a center plane, which contains the cylinder axis and extends normally to a guide plane, in which the two guide axes lie.
