THE POWER OF MOMENTUM. The Autostop™ II uses the forward mementum of your towed vehicle to effect a smooth, quick stop - reducing braking distances as much as 30 percent. Autostop™ II can be installed without modification to your RV or towed vehicle so when your RV slows down, the momentum of the towed vehicle pushes AutoStop™ II into the hitch. AutoStop™ II retracts the cable, proportionally activating your car's brakes. The more force applied, the tighter the cable, so you're assured of full braking power at any speed!
