Failure Symptoms

A failing relay valve may initially present as a slight delay in brake application or a soft brake pedal feel. If left unaddressed, this can progress to inconsistent braking performance or complete loss of air pressure to the brake chambers. The ultimate risk is compromised vehicle control and extended stopping distances.

Installation Tip

Ensure all air lines are properly identified and connected to the correct ports on the new valve to avoid system malfunction. Do not use excessive force when tightening the mounting hardware, as this can damage the valve body.

Service Note

Inspect all air lines and brake chambers for leaks or damage when replacing the relay valve.
