Abstract: A disc brake includes brake pads (7), which are slidably received on either side of a brake disc within guide portions (6) of the disc brake, and including a spring arrangement (10) for spring cushioning the brake pads (7). Disc brakes of this type are frequently used in motor vehicles. To improve the spring cushioning of the brake pads, the spring arrangement (10) is equipped with at least one radial spring element (11) for radially clamping the brake pads (7) with respect to the guide portions (6), at least one axial spring element (22) for axially clamping the brake pads (7) in relation to each other, and at least one tangential spring element (18) for tangentially clamping the brake pads (7) in relation to the guide portions (6). The three spring elements (11, 18, 22) act in different spatial dimensions and can be embodied as separate components which are independent of each other.

Abstract: Floating-caliper brake including a brake support member, a floating caliper straddling the outside edge of a brake disc and being axially displaceably guided on the brake support member, brake pads arranged on either side of the brake disc and enclosed by floating caliper, with at least two of the brake pads being arranged on the axially inside surface of the brake disc and at least two of the brake pads being arranged on the axially outside surface, the inward brake pads being displaceable on the brake support member. An object of the invention in a floating-caliper disc brake of this type is to achieve a design with reduced weight and, additionally, enhance the assembly and improve the function of the brake. This object is achieved in that the two outside brake pads are supported by arms of the brake support member that straddle the brake disc, and in that the floating caliper makes catch at the two outside brake pads simultaneously. The sub claims disclose favorable improvements of the invention.

Abstract: A brake shoe for spot-type disc brakes. The novel brake shoe incorporates a retaining spring which is fixed to the brake shoe's backplate and which is intended to engage a hollow portion of a brake piston. Preferably the backplate is coated with a silencing varnish paint for noise abatement. A fixing section of the retaining spring is formed with a step which is in abutment against the backplate in a range devoid of silencing varnish paint. The retaining spring is secured to safeguard against twisting. The operability of the retaining spring is preserved, independently of the accidental thickness of the layer of silencing varnish paint.
