The power of momentum.

The simplest braking system we offer, AutoStop uses the forward momentum of your towed vehicle to effect a smooth quick stop, reducing braking distances as much as 30 percent. AutoStop can be installed without modification to your RV or towed vehicle, so it won't add wear and tear on your RV's brakes. And its mechanical design allows the braking system to be easily transferred to another vehicle should you happen to trade your car or coach.

Available for all ball mounted tow bars and universal motor home-mounted tow bars.
Rated for vehicles up to 5000 pounds.
SS version rated for vehicles up to 7500 pounds.
Adjustable to your driving style and conditions or terrain.
Requires towbar to be within 2" of being level.
Five-year warranty.

How it works. 
When your RV slows down, the momentum of the towed vehicle pushes AutoStop into the hitch. AutoStop 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.

Brakelock Extra protection guaranteed.
Provides added safety by locking the brakes of your towed vehicle should it ever disconnect from your RV. A growing number of states and provinces now require this measure of safety. Comply with these regulations and relax with Brakelock. (BX8881)

How it works. 
Mounted under the front of the towed vehicle, Brakelock operates without tapping directly into brake lines.
