Roadmaster 8700 Vehicle Mounted Direct Proportional System Towed Vehicle Brake Control Yes

InvisiBrake is a fully-automatic, progressive supplemental braking system that uses the electrical connections already in place on your towed vehicle (the towed vehicle’s electrical harness) to brake when you brake the motorhome — the same electrical signal that activates the towed vehicle’s brake lights also activates InvisiBrake.

• Fully-Automatic, Progressive Supplemental Braking System
• Completely Out Of Sight : InvisiBrake Is So Small It Can Usually Be Mounted Under The Driver’s Seat, Under The Rear Seat, Behind Interior Panels Or In The Trunk
• Progressive Braking : When You Apply More Braking Force, So Does InvisiBrake — The Longer You Apply The Brakes In The Motorhome, The Harder Your Towed Vehicle Will Brake
• Two-Stage Motorhome Monitor : InvisiBrake Includes An LED Monitor For A Visual Reference Of Braking Activity; An Audible Alert At The Motorhome Will Warn You If The Brakes Have Been On For Too Long
• Activates Only When The Motorhome’s Brake Lights Illuminate — No False Braking
• Works In Virtually Any Towed Vehicle — Including Those With 'active' Braking Systems
• Easily Adjusts To Individual Braking Preferences. Includes An Emergency Break Away System
• Limited 1 Year Warranty
