The present invention relates to a spot-type disc brake with a brake housing straddling a brake disc, with at least one brake pad that is arranged in the brake housing so as to be slidable in the actuating direction and cooperates tribologically with the brake disc upon brake application, with at least one actuating device arranged in the brake housing to apply an actuating force to the brake pad, and with a spring assembly for the active adjustment of a clearance between the brake pad and the brake disc after brake application. To simplify the configuration of the spring assembly, the spring assembly comprises exactly one spring which is secured detachably in the spot-type disc brake and is supported on the brake pad and on the brake housing. A spring of this type is arranged advantageously symmetrically within the brake housing to prevent an undesirable inclined positioning of the brake pads.

A spot-type disc brake comprises a brake support member and a brake caliper guided via pins mounted in the brake support member. The brake caliper pressurizes the brake shoes arranged on either side of a brake disc by virtue of a brake piston on a bore. The brake shoe lying opposite to the piston is supported on the end face in the brake caliper, while the other brake shoe bears against the end face in the brake support member. To prevent inclined positioning of the brake caliper which results in tapered wear at the brake shoes, the retaining arm arranged in the brake disc's direction of rotation at the brake disc exit is dimensioned such in cross-section that its deformation in the circumferential direction of the brake disc will not be much larger than the fit clearance available between the brake piston and the bore.

A brake shoe for a spot-type disc brake includes a carrier plate composed of several plates lying on top of one another, a backing plate and a friction pad secured to one surface of the backing plate. One surface of the carrier plate adjacent the friction pad includes flanges at the ends thereof to embrace the backing plates and the other surface of the carrier plate remote from the friction pad includes flanges to engage a supporting member of a brake housing to transmit the circumferential force at the friction pad during braking to the supporting member.
