Brake single or dual piston pusher tool

A piston pushing tool for use in piston disc brake assemblies having a caliper housing providing at least one piston receiving bore in which a piston is reciprocably disposed, the bore being open at one end and closed at its opposite end, and an outboard shoe support bracket spaced axially apart from the open end and having axially outer and inner surfaces and an opening therethrough generally aligned with the bore, the piston being a hollow cylindrical piston with a first end adjacent the closed end of the bore, and a second end adjacent the open end of the bore, the second end being closed and having an axially inner surface and an axially outer surface, the tool comprising:

• a threaded shaft having a distal end, a proximal end, and an intermediate portion, the shaft being proportioned and designed to extend axially through the opening in the support bracket;
• means, attached to the proximal end of the shaft, for rotating the shaft;
• means, engaged on the intermediate portion of the shaft, for abutting the axially inner surface of the support bracket;
• and
• a second plate for abutting the second end of the piston, the second plate having a first surface, a second surface and two spaced apart U-shaped extensions, the second surface being attached to the distal end of the shaft;
• wherein upon rotation of the rotating means, the second plate will be driven away from the axially inner surface abutting means, thereby pushing the piston fully into the at least one piston receiving bore.
