Description

The Roadmaster Inc 8700 InvisiBrake is a fully-automatic, hidden supplemental braking system for towed vehicles. It connects to the towed vehicle's electrical harness, activating the brakes in conjunction with the motorhome's brake lights. The compact unit (8¾" x 8¾" x 2¾") can be installed out of sight (e.g., under a seat). It continuously trickle-charges the towed vehicle's battery during towing. The system features a two-stage motorhome monitor with an LED indicator and an audible alarm for prolonged braking. It includes an emergency breakaway system and allows for adjustable braking pressure (5 to 100 psi). The InvisiBrake works with nearly all vacuum-powered brake systems, including hybrids and vehicles with active braking systems, and complies with U.S. and Canadian braking regulations.
