Product details
The Roadmaster 8603 Replacement Coiled Break Away Cable is an essential safety component designed to maintain a reliable, tangle-free connection between your motorhome and towed vehicle as part of the Roadmaster BrakeMaster braking system. Built with a durable, heavy-duty coiled design, this replacement cable stretches easily during turns and vehicle movement, then retracts neatly when not in use, preventing dragging, kinking, or snagging. The coiled construction not only keeps your setup organized and professional-looking but also ensures consistent tension, so the break away switch activates instantly and accurately if a separation occurs. Engineered to the same high standards as all Roadmaster components, the 8603 cable is made from premium materials that resist corrosion, wear, and UV damage for long-lasting durability even under continuous outdoor exposure. Installation is quick and straightforward, using standard connection points to integrate seamlessly into your existing BrakeAway system. By replacing worn or damaged cables with the Roadmaster 8603, you restore full functionality and maintain the vital safety link that ensures your towed vehicle brakes engage properly in an emergency. Whether you’re maintaining your current setup or performing a full system refresh, this coiled cable delivers dependable performance, secure connectivity, and the peace of mind that comes with Roadmaster’s trusted engineering and build quality—keeping your towing system safe, reliable, and ready for the road ahead.
