Installation & Application Notes

Failure Symptoms

The first sign of a failing valve is often a delay in parking brake application or release. If ignored, the parking brake may become unreliable, intermittently failing to hold the vehicle or releasing prematurely. This can compromise vehicle safety during parking or on inclines.

Installation Tip

Ensure the air system is fully depressurized before disconnecting any lines to prevent sudden air release. Do not overtighten fittings, as this can damage the valve body or threads.

Service Note

Inspect air lines for cracks or leaks and clean the air dryer system when replacing this valve.
