Abstract: A manual means for reducing the time and effort needed to retract a brake-actuation piston into a brake fluid-containment cylinder during a brake pad-replacement operation. A thrust plate has a threaded hole meshed with an elongated screw that is turnable manually to exert a retractive force on a brake-actuation piston.
