ABSTRACT:
A new disc brake assembly tool for providing an easy means for positioning a piston into the piston cylinder of a caliper to provided proper clearance so that a disc brake pad may be installed. The inventive device includes a base having an elongate center 1t portion, an arm portion, and a foot portion. The arm and foot portions are extended substantially perpendicular from the center portion and are spaced apart from one another. A mount member is coupled to the terminal end of the arm portion. The mount member has a mount bore extending therethrough. Inserted through the mount bore is a tubular sleeve having a threaded lumen. the sleeve being positionable within the mount bore between an extended position and a retracted position. The proximal end of the sleeve has a radial flange outwardly extending therefrom. An elongate threaded rod is threadingly extended through the threaded lumen of the sleeve with the distal end of the threaded rod extending from the distal end of the sleeve and its proximal end extending from the proximal end of the sleeve. The threaded rod is threaded in the sleeve so that it is expendable towards the foot portion. A second biasing assembly biases the sleeve away from the foot portion. The foot portion has a slot therethrough between its surfaces which extends from the terminal end of the foot portion towards the central portion. The threaded lumen of sleeve is aligned with the slot such that the longitudinal axis of the lumen extends through a portion of the slot so that the proximal end of the threaded rod is extendable through the slot of the foot portion.
