Abstract: A brake pad 10 can brake a rotation of a disc 200. The brake pad 10 includes a friction material 12 provided on the side of the disc 200 and a back plate 11 bonded to the friction material 12 on the opposite side of the disc 200.

Abstract: In order to realize a two-piston floating caliper disc brake with a wide caliper, the axially outer side of the caliper is supported by radially extending protrusions shaped on the outer brake shoe. While the two protrusions have the same depth, they differ in their width. Corresponding circular grooves within the caliper around recess openings on the opposite side of the brake cylinders, however, are identical. Therefore, a radial support of the brake caliper can be carried out by both protrusions while a tangential positioning of the caliper is limited to the wider one of the two protrusions.

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.
