Description

The Vcsii Power Cable (8.0M) is a critical component within air brake systems, specifically designed for use with Wabco's VCS systems on semi-trailers.

The cable's robust construction and OE specification ensure reliable power delivery and consistent performance, enhancing the overall safety and efficiency of the braking system. Dimensions are 100 x 380 x 380 mm. The MPN for this cable is 4491320800.

Key Features & Benefits

This cable basically delivers electrical power from your tow vehicle to the trailer’s braking system. It carries the signal that tells the trailer brakes when to activate, and how strongly. It’s a pretty simple part, but absolutely crucial for safe towing. It provides power for the electric or electro – magnetic trailer brakes themselves, and also for any related functions like brake lights on the trailer. Think of it as the nervous system connecting your truck or SUV to the trailer’s brakes. When you hit the brake pedal in your tow vehicle, that signal travels through this cable, telling the trailer’s brake controller to apply the brakes back there. It's specifically designed for air brake systems used on trailers, so it's a heavier duty cable than you might find for just lights. It plugs into the back of your tow vehicle and then into the trailer connector.

Symptoms, Risks & Replacements

Well, without this cable working properly, your trailer brakes won’t work at all, or they’ll work intermittently. That's a really serious safety issue, obviously. You’ll notice if this cable is damaged, frayed, or has a bad connection—you might experience weak or unresponsive trailer brakes, or even no brakes at all. It acts like a shield protecting the signal that keeps everything safe while towing. If you’re doing a repair or upgrade to your trailer brake system, it's always smart to check this cable and replace it if it's looking worn. You can find these pretty easily, and we carry them at Fixparts Online, along with everything else you'll need for your trailer's air brake system.
