Abstract:
1. A braking system of a motor vehicle, comprising: an active brake pads refraction system comprising: a metering check valve at each brake corner disposed between said hydraulic brake line and the brake caliper thereof, said metering check valve having a predetermined retraction volume therewithin, wherein brake fluid flows through said retraction volume in a first direction in response to brake pad application, and in a second direction, opposite to said first direction, in response to brake pad retraction; wherein when said active brake pads retraction system pressurizes said brake fluid to a pressure below atmospheric pressure, then said brake caliper responsively retracts said brake pads away from each other; and wherein the brake pads retraction is provided by brake fluid passing through said metering check valve in said second direction such that the retraction is limited by the retraction volume.
