ABSTRACT:
A tool is used to move the piston into the cylinder bore of a disc brake caliper housing having a support bracket with an opening disposed opposite the piston. The tool comprises a threaded shaft having a piston engaging member rotatably connected at one end of the shaft. A shaft rotating member is rigidly secured to the other end of the shaft. A brace member threadingly engages the shaft member at a location intermediate the two ends thereof. The brace member has a structural configuration to abut the inside surface of the support bracket of the caliper housing. The brace member also is effective to span the opening to position the shaft member within the opening so that the piston engaging member can be moved directly toward the piston. The piston engaging member is effective to exert a pressure against the opposing edges of the piston when the brace member abuts the inside surface of the support bracket.
