Abstract: A disc brake caliper tool is set forth wherein a plurality of generally "L" shaped offset jaws are provided with confronting surfaces to impinge on a respective individual of a pair of disc brake pads within a caliper of an automotive disc brake assembly. The offset jaws are actuated by a toggling actuation mechanism in turn actuated by a plier-type plurality of force application handles wherein an individual of said handles is provided pivotally thereto with an adapter bar pivotal from a first position adjacent and parallel to said handle to a second position parallel to but coextensive to said handle for deflecting a disc brake caliper without removal of said caliper from association with a rotor.
