A disc brake caliper consists of a body member including a cylinder portion, and a bridge member attached to the body member by two bolts. The body and bridge members of the caliper abut one another at two pairs of parting faces lying in a common plane, aligned bolt holes for the two bolts being formed in the parting faces. The cylinder portion of the body member extends axially beyond the parting plane so that a recessed portion of the bridge member overlies but is spaced from the cylinder portion to form an air pocket which is adequately vented. The two parting faces on the body member can be machined simultaneously by means of two broaching tools which clear the cylinder portion.

Disc brakes

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.
