Brake Quick-Release Valve
Bendix

Designed for heavy‑duty air brake systems, this valve vents the brake line to atmosphere during release, enabling a fast, controlled disengagement of the braking mechanism. The unit sits in the primary air circuit and works to shorten the time from pedal release to wheel rotation, improving overall release smoothness and driver confidence in stop‑and‑go operations. With rugged construction and seals engineered to withstand moisture, dust, and wide temperature swings typical of highway use, it maintains reliable performance across varied climates. A clean venting action helps prevent brake drag on long descents and reduces unnecessary heat buildup in the brake system, which translates to better efficiency and longer service life for adjacent components. The valve is built to Bendix‑style tolerances, ensuring a straightforward installation with standard fittings and predictable venting characteristics even in multi‑chamber configurations. Replacing a worn unit restores proper release timing, preserves pedal feel, and minimizes inconsistent braking behavior under load. This part is a critical contributor to safe, responsive braking in demanding commercial applications. Source One Parts Center.
