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.
