Its dimensions are 58 x 286 x 258 mm, and its total length measures 1.50 m with an additional 400.0 mm segment.

Key Features & Benefits

This cable, pretty simply, transmits the signal from your truck’s brake pedal to the electric brakes on your trailer. When you hit the brakes in your truck, that signal travels down this cable and tells the trailer brakes to engage. It's a direct connection, a physical link telling those trailer brakes what to do. It’s got a plug on one end to connect easily to your truck’s connector, and the other end goes right into the brake controller on the trailer. Think of it like an extension of your truck's braking system. Your truck handles the initial stopping power, but this cable is what tells the trailer to slow down with you. Without it, the trailer will keep rolling, and that's a scary situation. It’s part of the overall air brake system, making sure everything works as one unit. It's not something complicated mechanically, but it's absolutely essential.

Symptoms, Risks & Replacements

This is a safety item, plain and simple. If this cable fails, you lose the ability to effectively control the trailer's brakes. You'll notice if it’s failing; you might have weak brakes on the trailer, or they might be intermittent, or you might not even get any braking action at all from the trailer. It acts like a shield, protecting you from a runaway trailer. A broken or frayed cable can cause serious problems, so it’s good you’re looking at this. You can find a replacement easily enough—we keep them in stock, and sites like Fixparts Online are good for finding these parts too. It’s a relatively inexpensive part to replace, but it’s worth the investment to keep everything running safely.
