Troubleshooting Demco SBS Duo Supplemental Braking System that Pulses Brakes

Updated 05/12/2021 | Published 05/11/2021

Question:

When I hooked up my 2010 Jeep Wrangler, all systems seem to be working ok until I started pulling away. The jeep started pulsing, like the brakes were being tapped on. I stopped and my wife looked that the brake in the Jeep while suppressed the brake in the RV and it worked fine. When we started again it did the same thing. not sure if I need to re-adjust to knob on the switch box or what.

I recently asked Demco about brakes pulsing with the install of the Demco SBS Stay in Play part # SM99251 and they said this was normal if the sensitivity was cranked up too high and near the max setting. Have you set the sensitivity setting of your setup yet? Most likely you just need to adjust it to a lower setting and the pulsing will stop.
