Abstract: A floating caliper-type disk brake for automotive vehicles, for supporting the circumferential forces and for guiding the brake pads including a brake carrier integrated into the steering knuckle of the vehicle. To insure a simple final assembly on the vehicle and to facilitate an automatic assembly, the floating caliper with brake pads attached thereto is supplied as a pre-assembled unit. The brake pads by means of leaf springs secured to their back plates are detachably fixed to the floating caliper. In the practice of the invention, the leaf spring of the outer brake pad, additionally serves to radially prestress the floating caliper vis-a-vis the carrier arms of the brake carrier, thereby eliminating another spring provided for this purpose. The assembly of the floating caliper on the vehicle is simplified because there is no need to assemble the said additional spring.

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.
