Trailer Brake Module (optional)

The trailer brake module controls the braking functions of a trailer equipped with electric brakes. There have
been many styles of brake modules used. All of the brake modules that have been used function the same
other than that the location of the manual adjustment controls may vary.
The brake module will be located under the dash tray to the left of the steering column. It has a red indicator
light (LED), a Thumb wheel braking force adjustor, a Pendulum level adjustment lever, and a Manual
Braking lever.
As the vehicle slows during braking, the brake module sends a signal to the trailer energizing the trailer
brakes. This signal is proportional depending on how fast the vehicle is stopping.
LED: The LED's brightness is related to the braking force
at the trailer, dim with little or no signal to bright at maximum
braking force. Once the vehicles has stopped, the LED
will remain at it's dimmest intensity as long as the brake
pedal is depressed.
Thumb wheel: The thumb wheel is used to adjust how
much braking force is sent to the trailer brakes. Rotate the
thumb wheel upward towards the top of the housing to
increase the braking force.
Pendulum Lever: The brake sensor inside the module
must be level for it to function correctly. The pendulum
lever is used to level the internal brake sensor. Perform
the following steps to adjust the sensor:
1 This adjustment must be done with the trailer disconnected from the vehicle.
2 Stop the vehicle on a level surface but do not release the brake pedal.
3 Adjust the thumb wheel to its minimum position downward towards the bottom of the module case.
4 Pull the pendulum towards the front of the module case. The LED should be at it's maximum intensity.
5 Slowly push the pendulum towards the rear of the module case and stop when the LED just reaches
its minimum intensity. The pendulum should be very close to vertical.
6 Repeat the previous two steps a few times to be sure that the pendulum is at the correct position.
Manual Braking Lever: The manual braking lever can be used to manually apply the trailer brakes. Slide
the lever to the left to apply the brakes. The braking force is proportional depending on how far the lever is
moved.
