Its dimensions are 0.23 x 0.09 x 0.09. The calculated volume is 0.000000001863 and the distance between holes is 61x61 mm. It incorporates a silencer for exhaust, contributing to quieter operation.

Key Features & Benefits

This thing basically controls the air pressure to your spring brakes. It's a mechanical valve operated by your foot – when you push the pedal, it lets air into the brake chambers, releasing the spring brakes. When you let off the pedal, it vents the air, and the springs apply the brakes. It handles both applying and releasing those emergency and parking brakes. Think of it as a key part of your safety net. It’s tied directly into your spring brakes, which are what stop the vehicle even if you lose air pressure in your main brake system. It’s a totally mechanical system, meaning it doesn’t rely on electricity or anything else to work – it's pure pedal power. It’s typically found in heavier duty vehicles like trucks, buses, and some larger trailers.

Symptoms, Risks & Replacements

It's critically important. If this valve fails, you could be looking at a situation where your spring brakes don’t release properly, or worse, don’t apply when you need them. You’ll notice if it’s going bad – maybe the pedal feels spongy, or it takes a lot more effort to apply or release the brakes. It acts like a shield, giving you that crucial stopping power as a backup. You can find replacements pretty easily - we carry them here, and Fixparts Online is a good resource too if you prefer to look around. It's one of those parts you really don’t want to put off fixing if it starts acting up.
