Abstract: A brake caliper retracting tool for pushing a brake caliper piston into a piston housing to provide space for installing a brake pad in the caliper. The brake caliper retracting tool includes a housing with proximal and distal ends, and an inner surface defining an interior cavity in the housing. An elongate shaft is slidably extended through the distal end of the housing into the interior cavity of the housing to permit slidable extension and retraction of the shaft in and out of the interior cavity of the housing. A plunger is disposed in the interior cavity of the housing and is coupled to a proximal end of the shaft. A backing plate is coupled to the distal end of the housing. A pushing plate is coupled to a distal end of the shaft. A passage extends through the proximal end of the housing and is designed for connecting to an air supply to permit passage therethrough of air into the interior cavity.
