The Wabco 9760001030 ABS Relay Valve Assembly is a genuine Wabco tractor ABS relay valve package for 4S/4M anti-lock braking systems. It runs on 12 V, has a maximum operating pressure of 159.5 psi, and works across a temperature range of -40°C to +80°C, with a response pressure of 0.38 bar and protection classes IP 6K6K and IP 6K9K. A relay valve takes the small air signal from the brake circuit and uses it to open a path for full supply air to the brake chambers, so the brakes apply quickly, then vents the chambers when the pedal is released. A worn or leaking valve shows up as slow brake application, weak response, or uneven wear from one wheel end to the next. Supersedes part number(s) S976-000-103-0. Call us to confirm proper fit.
