A piston pushing tool for use in piston disc brake assemblies having a caliper housing with at least one piston receiving bore open at one end and closed at its opposite end in which an hollow cylindrical piston having a closed end adjacent to the open end of the bore is reciprocably disposed, and an outboard shoe support bracket spaced axially from the open end of the bore and having axially outer and inner surfaces and an opening therethrough generally aligned with the bore. The tool includes a threaded shaft having a distal end, a proximal end, and an intermediate portion. The shaft is proportioned and designed to extend axially through the opening in the support bracket. A handle is connected to the proximal end for rotating the shaft. A first plate is provided for abutting the axially inner surface of the support bracket and a second plate, connected to the distal end of the shaft and having two spaced apart U-shaped extensions, is provided for abutting the closed end of the piston. Upon rotation of the shaft, the second plate is driven away from the first plate, thereby pushing the piston fully into the at least one piston receiving bore.
