Key Features & Benefits

This lever basically controls the application and release of the spring brakes. It’s how the driver manually kicks in those emergency or parking brakes. It also has a role in controlling the trailer supply air – think of it as a central control point for the air flowing to the trailer brakes. It’s a mechanical and pneumatic switch, if you will – it physically moves things, and directs the air pressure where it needs to go. It’s a key part of your air brake system, obviously. It physically pulls cables that activate the brakes when you want to really stop things, or hold them when parked. It’s usually mounted inside the cab, easily accessible to the driver. It also connects directly to the air lines that run to the trailer, letting you manage braking there too. It’s a pretty central point for overall brake control.

Symptoms, Risks & Replacements

Well, if this thing fails, you lose the ability to reliably engage your spring brakes. Those are your fail – safe brakes, what stops you if you lose air pressure. It’s kind of like a shield for your safety. You’ll notice if it starts to get sticky or isn’t pulling the brakes fully. It needs to work every time. Beyond that, if it's malfunctioning regarding trailer air supply, you could end up with the trailer brakes not working correctly, and that’s a serious hazard. We carry these at Fixparts Online, and getting a replacement isn’t too bad if you catch it early. It's a relatively simple part, but vital to keep your rig safe.
