It speeds up brake application and release by using a small control air signal to proportionally deliver a larger volume of air to the brake chambers, ensuring consistent, responsive braking across multiple axles. This replacement part is typically installed on trucks and trailers when the original valve begins to leak, stick, or cause delayed brake response.
