Abstract: A brake shoe (12) is guided on an anchor plate (10) of a drum brake and held down by a pin (32) which extends through a hole (34, 36) each in the anchor plate and in a web (18) of the brake shoe (12). The pin (32) has a foot (38) which is supported on the anchor plate (10) and a head (42) which has a bottom of rotationally symmetrical configuration with respect to the pin (32) and rises radially outwardly. Between the head (42) and the web (18) a spring (46) is arranged which has a receiving portion (50) formed with a recessed seat (52) for the head (42) and with a slot (60) which serves for radially slipping the receiving portion (50) on to the pin (32). The seat (52) is shaped like a funnel having a circular upper edge (54). The slot (60) is defined by a pair of outer edges (62) and a pair of adjoining inner edges (64). The outer edges (62) of the slot (60) converge in the direction of the upper edge (54) of the seat (52).

Abstract: The present specification discloses and claims an opposed piston disc brake caliper of the fixed type together with a pad anti-rattle spring for use therewith. The caliper is formed in two halves, each half having a machined surface in which a pad recess is formed. The caliper halves when clamped together with the machined surfaces engaging each other, leave part of a machined surface exposed at least at one side of a friction pad locating aperture formed by the two pad recesses. This exposed part of the machined surface acts as a datum surface against which part of the pads anti-rattle spring can engage. The pad anti-rattle spring has a generally rectangular configuration and is dimensioned to fit into the pad locating aperture. At least one window is cut in the spring to allow for inspection of pad wear, and a lateral tag is provided on the spring in the region of the or each datum surface.
