Abstract: 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.
