Key Features & Benefits

This cable basically transmits the signal from your brake pedal to the air brake system on your trailer. It’s a mechanical link, a simple cable, but it’s critical for telling the trailer brakes when to activate. It carries the pressure – not the air itself, just the instruction to open the valves that release the air to the brakes. It’s got a pretty specific connection at both ends to make sure it seals properly and doesn’t leak that signal. Think of it as a messenger. When you hit the brakes in your tow vehicle, that motion gets translated down this cable. The cable physically moves parts inside the trailer brake control unit, which then tells the trailer’s air brakes to engage. It's a core piece in making sure your trailer stops when you do. It's part of the whole system, of course, working with the air compressor, lines and everything else.

Symptoms, Risks & Replacements

This is one of those things you’ll notice if it goes bad – and you’ll really notice it. If the cable fails, you might get delayed braking, or even no trailer braking at all. That’s a serious safety issue, obviously. It acts like a shield, protecting the crucial brake signal. Over time, the cable itself can stretch, fray, or the ends can corrode, which messes with the signal and causes problems. If you're getting inconsistent trailer braking, or it feels like the trailer is pushing you around a bit, this is something to check. We carry these at Fixparts Online, and they’re a fairly straightforward replacement, but if you're not comfortable doing brake work, definitely have a professional take a look.
