Similar to a surge-type trailer brake actuator, the AutoStop uses the momentum of your towed car as your RV slows to trigger the car's brakes to activate. Replaces the hitch bar on your Blue Ox Aventa LX tow bar for quick, easy connecting.
Towing your car has never been easier than with the AutoStop from Blue Ox. Setting up this supplemental braking system is a snap. Because the AutoStop connects to your Aventa LX RV-mounted tow bar (sold separately), you can slide the entire unit into your RV's trailer hitch in one fell swoop. Connect the actuating cable to the brake pedal cable - which is attached to your tow car's brake pedal - and you're good to go.
Removing the system is just as easy. The cables have a quick-disconnect feature so you only have to unplug them. Just wrap up the excess brake pedal cable and store it in your towed car. Then remove the tow bar and brake system setup from your RV's hitch. It's that simple. The AutoStop stores conveniently along with your tow bar. No need to dig out a space to stow a bulky braking unit.
A vast improvement over on/off systems, which brake at a single preset level, the AutoStop has a proportional design for equal braking. This system will activate the brakes in your towed car with an intensity that matches the braking action of your RV. The result is uniform braking across your setup. No push-pull action - just smooth, proportional braking every time.
When you apply the brakes in your RV, deceleration occurs and momentum pushes your towed car toward the rear of your RV. When this happens, the AutoStop contracts, applying force to its inner components. Once the internal power spring is compressed, a series of internal pulleys are set in motion. The actuating cable, which is wrapped around these pulleys, will then be tugged. This action causes the brake pedal cable - the cable that is wrapped around your towed car's brake pedal and attached to the actuating cable - to pull on the brake pedal of your towed vehicle. As a result, the brakes in your towed car will activate.
Because the intensity with which the cable tugs on your towed car's brake pedal is directly related to the intensity at which your towed car forces the AutoStop to compress, your towed car will brake proportionately to the braking action of your RV. In other words, if you slam on the brakes in your RV, your towed car's brakes will activate quickly and with maximum intensity. If you brake lightly in the RV, your towed car's brakes will activate more gradually and with less intensity.
You can also adjust the preload setting of the AutoStop, which affects the responsiveness of the system. Using the adjustment nut on the side of the unit, you can initially set the preload compression of the power spring based on the weight of your towed vehicle. Then take your rig out for a spin and test it out. You can increase the preload to lessen the sensitivity of the unit. If the preload is set to the maximum level, the AutoStop will only activate your towed car's brakes during heavy braking situations. If you set it too low, you may experience braking when you merely tap the RV brakes or when you drive down a hill.
Easy Installation and Removal
The AutoStop installs quickly and easily with no need for any modifications to your RV or towed car and no need to tap into either your RV's or towed car's brakes. The hardest part will be installing the brake pedal cable. To do this, you will have run the cable through your engine compartment and drill a small access hole through the firewall to route the cable into your car's interior.
To set up the AutoStop, just slide it into the 2" trailer hitch receiver on your RV and then insert your motor-home-mounted tow bar (sold separately) into the receiver tube that is built into the AutoStop. Connect the cable that is looped around your towed car's brake pedal to the actuating cable that comes off of the AutoStop. That's it.
To disconnect, just unhook the cables and remove the entire unit from your hitch. The AutoStop can easily be stored with your tow bar for next time - no need to find extra storage space for a bulky braking unit. The cable that is wrapped around your car's brake pedal can remain in place until you're ready to tow again. It will not interfere with normal brake pedal functioning.
Included with the AutoStop is an in-dash indicator light that installs in your RV and will inform you when the brakes in your towed car have been engaged. Most supplemental braking systems have some sort of indicator, but many of these activate when the braking unit activates, not necessarily when the towed car's brakes are applied. If you have an indicator like this one, which informs you when the brake pedal is actually being applied, you can prevent false braking.
To install this indicator, splice the included automotive relay into your towed car's wiring between the brake light switch and the brake lights. This is to ensure that the signal sent to the indicator is actually from the vehicle and not from the braking system. By splicing into the wire at this point, you ensure that a signal will only be sent when the brake pedal is being depressed. Once the relay is in place, connect it to the included yellow wire and then route that wire out to the front of the towed car. This wire connects with the wire on the indicator that installs in the dash of your RV.
