摘要：
Brake pads are retracted with respect to the brake rotor responsive to predetermined conditions of the motor vehicle in which braking is not required. Selective application of negative brake line pressure causes the caliper pistons to retract with respect to their respective caliper cylinders, thereby causing the brake pads to retract from the brake rotor. The predetermined conditions of the motor vehicle when braking is not required include when the motor vehicle is cruising or is parked.
