Wabco 4494440640 Cable

Description

This Wabco cable (MPN 4494440640) is a critical component within air brake systems, specifically designed for trailer brake controls. It’s used to connect the VCS system to the ABS Modulator with a Y-type configuration, utilizing 2x bayonet socket DIN 72585-B1-3.1-Sn/K1 4-pin connectors on one end and a 5-pin connector at the modulator. Measuring 50 x 330 x 330 mm, this cable meets OE specifications, ensuring reliable performance and seamless integration within existing air brake infrastructure. Its robust construction and precise engineering contribute to consistent brake functionality and enhanced safety for trailer applications.

Key Features & Benefits

This cable physically connects your control valve – usually in the cab of your truck – to the trailer’s brake actuators. It transmits the force you apply when you hit the brake pedal. Basically, when you press the pedal, this cable pulls on the brakes on the trailer. It’s a simple mechanical connection, but it needs to be solid. Sometimes these are adjustable, so you can fine – tune how much the trailer brakes activate compared to the truck. Think of it as a vital link in the chain of stopping. Your truck's brakes stop it, and this cable lets you apply braking force to the trailer too. Without it, the trailer keeps rolling, which is obviously a big safety issue. It’s part of the air brake system, so it works with air pressure and the mechanical pull to activate the trailer's brakes.

Symptoms, Risks & Replacements

It’s critical for safe towing. You’ll notice if this cable stretches or breaks – the trailer will feel like it’s pushing you, and you’ll lose effective trailer braking. That's a really dangerous situation. It acts like a shield against runaway trailers, preventing accidents. These cables do wear out over time from stretching, corrosion, and just general use. If it’s frayed, damaged, or doesn’t have smooth movement, it needs replacing. We carry a good selection of these at Fixparts Online, and getting a new one is a lot cheaper than dealing with the consequences of a failure.
