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. The tag or tags can be engaged with the datum surface on the caliper to correctly locate the spring and allow accurate inspection of the pads through the at least one window.
An opposed piston disc brake caliper of the fixed type comprising two caliper halves, a machined surface being provided on each caliper half, a pad recess being formed in each machined surface, the caliper halves being clamped together with their machined surfaces engaging each other, the pad recesses together forming a friction pad locating aperture, and part of at least one of said machined surfaces being exposed at least at one side of the friction pad locating aperture whereby the exposed part of the at least one machined surface provides a datum surface for accurate measurement relative thereto, and a spring of generally rectangular configuration, a window aperture in said spring, and a laterally projecting tag being arranged on at least one side of the spring to engage against said datum surface of the caliper to correctly locate the spring in the pad locating aperture enabling accurate inspection of brake pad wear.
