Breakaway Switch
The breakaway switch is one of the most important parts of your trailer electric brake
system. The very instant a breakaway occurs, the pull pin which is linked to the tow
vehicle, is pulled from the switch. The two contacts automatically close to complete the
electrical circuit and apply the trailer brakes. This system will apply the brakes of the
trailer if it would break away from the tow vehicle. A 12-volt battery is required to power
the breakaway switch.

WARNING: NEVER use the breakaway switch and trailer brake
system as a parking brake. Usage in this way would place undo strain
on the battery and converter, potentially causing damage to the wiring,
connectors, brakes and breakaway switch.

Hydraulic (Option for Kiwi 17A & 18F Only)
Your travel trailer may be equipped with hy-
draulic surge brakes. These brakes operate
automatically as the tow vehicle’s brakes are
applied. When the tow vehicle operator begins
to decrease speed and apply the brakes, the
weight of the moving travel trailer pushes for-
ward and the coupler moves downward. This
pressure moves the plunger, which in turn
pushes the piston and rubber cup inside the
master cylinder. Brake fluid presses inside of
the wheel cylinder and activates the brake shoes
against the drum.
Backing Your Travel Trailer
As designed, the weight of a travel trailer pushing forward will activate the surge brake
system. When backing a camper up a hill, the weight of the camper may activate the
brakes, making it difficult to continue to reverse.
1. Prior to backing up a slope or through soft ground, pull the travel trailer forward
slightly to assure that the actuator socket is in the forward position.
2. Move the lever (Fig. 3-5) knob 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.
Wheel Torque Requirements
Wheel Size 1st Stage 2nd Stage 3rd Stage
13-inch 20-25 35-40 50-75
14-inch 20-25 50-60 90-120
Digital or dial torque wrenches are the best to assure the proper amount of torque is being
applied. Further assistance may be obtained by contacting your Independent Jayco
dealer.
BRAKES
A controller should be installed below the dashboard of your tow vehicle to work in
conjunction with the travel trailer brakes. Two types of controllers are available. The
“hydraulic” controller operates through a steel line attached to the master cylinder of the
tow vehicle’s brake system. The “electronic” controller, operates using electrical current.
Reference the operating instructions provided with the controller for adjustment and
operation procedures. Practice coordinating the trailer brakes with the tow vehicle brakes
before towing your vehicle at higher speeds or significant distances. Employing the trailer
brakes before the tow vehicle brakes will reduce swaying.
Electric
Electric brakes on your recreation vehicle are designed to work in conjunction with the
hydraulic brakes on your tow vehicle. This means that in order to have the best brake
performance on both systems, the trailer and tow vehicle must perform and operate
together. Any attempt to use either brake system alone will cause accelerated wear and
damage.
The battery in the tow vehicle is the primary power source that operates the brakes in
your travel trailer. Keep your battery and charging system in working operation to ensure
available energy when required.
From the battery, power is sent to the controller to provide the correct amount of current
to brake the travel trailer. Use the tow vehicle’s brake pedal control for general operation
on combined use of both brake systems. The controller’s manual control is to be used
only in special situations such as indicated in the instructions supplied with control. In
the open position, the manual control breaks the electrical current preventing brake
engagement. When in the closed position, electrical current will flow to the brake
assemblies.
Wiring to operate your brakes must be sized in both vehicles, suggesting a minimum of
14 gauge. Your camper has 14 gauge wire from front end to brakes.
Brake assemblies are wired in parallel, never in a series. Being parallel, there will be
equal voltage and amperage at each brake assembly for equal braking capability and/or
performance.
WHEN YOUR TRAVEL TRAILER IS NEW IT IS IMPOSSIBLE TO ADJUST
YOUR BRAKE SHOES PRECISELY. IT TAKES APPROXIMATELY 1,000
MILES AND/OR 50 MEDIUM TO HEAVY STOPS TO “BURNISH” FIT OR
SEAT THE SHOES TO THE DRUM. AFTER THIS INITIAL BREAK-IN, YOU
CAN NOW ADJUST YOUR SHOES ACCURATELY FOR BEST PERFORMANCE
AND INCREASED DURABILITY.
