Abstract
A tool for retracting pistons into cylinder bores is disclosed. A plurality of centering cones are provided to engage with a multitude of piston sizes and configurations. A user selects an appropriately sized centering cone and engages the selected centering cone with a spring loaded distal pusher portion of said tool. A female threaded collar and spreader plate combination receives a male threaded thrust bolt. The male threaded thrust bolt carries the spring loaded distal pusher portion. The spreader plate is pressed against a face of the caliper assembly, and rotation of the male threaded thrust bolt by a driver, such as a ratchet wrench or impact gun, applies inward and rotating forces from the spring loaded distal pusher portion of said tool to the piston, while separating the spring loaded distal pusher portion of said tool from the spreader plate.
