Key Features & Benefits

This valve basically controls the air pressure going to the trailer brakes, and more importantly, releases that pressure when you take your foot off the brake pedal. It manages the airflow, letting air out of the trailer brake lines. It's a key part of how the system lets those trailer brakes disengage. It also has a priority feature – meaning if there’s a problem with the spring brakes on the trailer, this valve can help maintain some control. Think of it as the gatekeeper for the air pressure to your trailer brakes. It's installed in the air line that runs between your tow vehicle and the trailer. It's part of the whole system that lets you safely and effectively slow down and stop your trailer. It works with the emergency spring brakes—if those are engaged, this valve can help you try and regain normal braking function.

Symptoms, Risks & Replacements

Well, if this valve fails, your trailer brakes might not release properly, and that's a serious safety issue. You'll notice if it's acting up because the trailer might drag, or you could have trouble getting it to stop smoothly. It’s really crucial for preventing overheating of the trailer brakes too, because dragging brakes get hot, quick. You can find these pretty easily at places like Fixparts Online, but getting a good quality one is important. It’s not something you want to skimp on – it affects your safety and the safety of everyone around you.
