The brake controller should be installed in the tow vehicle to work in conjunction with the
RV electric brakes. Consult with your dealer or the brake controller OEM to decide what is
right for your towing combination.
The breakaway switch is a crucial part of the RV braking system. Located on the travel
trailer A-frame (or beside the fth wheel pinbox), this switch will apply the trailer brakes
if the trailer becomes detached from the tow vehicle. Attach the breakaway switch lanyard
to a permanent part of the tow vehicle (on a travel trailer do not attach it to the hitch ball or
similar removable parts) when hitching the trailer. If the RV becomes detached from the tow
vehicle, the pull pin will be pulled from the switch. This automatically causes the switch to
“close” and activates the RV brakes
Your RV may be equipped with hydraulic surge brakes that operate automatically as the tow
vehicle’s brakes are applied. When speed is decreased and brakes are applied, the weight of
the trailer moving forward creates a reaction, which causes the brake uid inside the wheel
cylinder to activate the brake shoes against the drum.
As a result of this design, backing the RV uphill may activate the surge brake system making
it dicult to continue in reverse. To aid in backing up the RV:
1. Prior to backing up a slope or through soft ground, pull the recreation vehicle forward
slightly to assure that the actuator socket is in the forward position.
2. Move the lever on the side of the actuator downward from the “towing position” along
the curved slot in the actuator frame to the “backup position.” The slot has a notch at
the bottom of its travel. Push the lever down to engage the locking notch.
3. The RV will now back up. This lever will slide into the correct position when pulling
forward.
It is extremely important to keep the master cylinder full at all times. An empty cylinder
invites moisture.
If your RV is equipped with disc brakes, see the manufacturer’s owner’s manual for detailed
safety and maintenance information.
Doing so would create a high amp draw on the battery and converter.
This can cause damage to wiring, connectors and the breakaway switch.
