For vehicles with brake pedal presets — Make certain that the cable and brake pedal clamp assembly were installed with the brake pedal as close to the driver’s seat as possible. MAKE CERTAIN THAT THE BRAKE PEDAL IS AT THAT POSITION WHEN TOWING. As an option, the brake pedal may be moved to the desired position and disabled. Do not rely on a mental note to never move the brake pedal.
Preparations for towing continued from previous page check the following: • Connect the cable at the rear of the motorhome, close to the center. Connecting the cable toward either side of the motorhome may cause the break away pin to be pulled when the motorhome turns, activating the break away system. • Be certain there are no obstructions which would prevent the cable from pulling freely away from the break away switch.
How to change the brake pressure continued from preceding page If InvisiBrake was professionally installed, make certain that the installer has lowered the brake pressure setting. CAUTION apply excessive force to the towed vehicle’s brake pedal, which will cause tire and brake system damage, as well as other consequential, non-warranty damage. Failure to follow these instructions may cause property damage, personal injury or even death.
Test InvisiBrake Following is a comprehensive test of InvisiBrake functions. We recommend that you perform this test before each towing season. Test InvisiBrake main functions The following tests can be performed with the motorhome and towed vehicle stationary. 1. Confirm braking — with the motorhome engine running, depress and hold the motorhome brake pedal down. The towed vehicle’s brake pedal will be depressed. Then, release the motorhome brake pedal. At the towed vehicle, the brake pedal will retract.
Troubleshooting continued from preceding page Symptom Solution The motorhome monitor LED does not illuminate, even though the brakes in the towed vehicle are being applied. • Make certain the brake light fuse was replaced in the towed vehicle. • Make certain that the monitor wire patch cord between the two vehicles is securely connected. • Make certain that there is an electrical ground between the motorhome and the towed vehicle.
