Abstract
A disc brake piston retractor tool is provided for retracting at least one piston of a caliper assembly. The tool includes first and second pressure plates having respective externally threaded first and second studs. A coupler is internally threaded to threadably receive the first stud and the second stud from opposite open ends of the coupler. Selective rotation of the coupler results in simultaneous lateral movement of the first and second pressure plates towards and away from the coupler between retracted and extended positions. One of the pressure plates is engageable against the at least one piston to retract the piston, and the other of the pressure plates is supported against an interior surface of the caliper assembly opposite the one piston, or is engagable against at least one other piston in the caliper assembly opposite the one piston to retract the other piston.
