In an active brake pads retraction system, the improvement is a metering check valve which limits the retraction. The metering check valve is interfaced with an anti-lock brake system (ABS), disposed in the hydraulic brake line between the brakes apply system of the ABS and a caliper member of the ABS located at each brake corner. Brake pads are retracted with respect to the brake rotor responsive to predetermined conditions of the motor vehicle in which braking is not required, wherein a retraction volume within the metering check valve limits the amount of brake pads retraction.
