4. Repeat Step (3) until power has been set

to a point just below wheel lock up or at

a sufficient force as to achieve maximum

braking power.

5. Using the brake pedal, make a few low

speed stops to check the Power and Level

adjustments. The automatic response

(brake pedal) is initiated and terminated

via the stoplight switch. When the brake

pedal is released, trailer braking will cease.

Fine Tuning

Now that the Power has been set, it is time

to fine tune the level setting for the majority

of the stopping that you will be doing.

1. Make several slow (25 MPH) stops as

if coming up to a stop sign and take

notice of how the trailer brakes respond:

✓ Brakes Grab Too Much

❑ You have an Aggressive Setting:

To correct this condition rotate level

knob clockwise, toward you, see below.

✓ Trailer Tending to Push Tow Vehicle

❑ You have a Delayed Setting:

To correct this condition rotate level

knob counter-clockwise, away from

you, see below.

2. Repeat until desired trailer braking

is achieved.

A. Delayed

B. Normal

C. Aggressive

Situation Probable Cause

Tow vehicle connected to trailer,

NO GREEN light.

1. Corrosion on trailer plug contact.

2. Loose POWER or GROUND connection.

Tow vehicle connected to trailer, light is

GREEN. When Manual Slide Knob is activated:

A. No RED light.

B. Light is dim RED or flashing RED.

C. Light glows dim RED and gets brighter

as POWER Knob is decreased.

1. POWER set at or near minimum.

2. Short on BRAKE line (BLUE wire).

3. BLACK & WHITE wires reversed,

control destroyed.

4. 12 volts from external source on BRAKE

line (BLUE wire).

1. Open on GROUND line (WHITE wire).

2. Short on BRAKE line (BLUE wire).

1. Short on BRAKE line (BLUE wire).

2. Defective brake magnets.

Braking with foot pedal is too aggressive. 1. Sensor set too aggressive,

see LEVELING SENSOR.

2. Power set too high.

Braking is delayed for extended period. 1. Sensor set improperly,

see LEVELING SENSOR.

2. Power set too low.

Tow vehicle connected to trailer, brake

pedal depressed:

A. No RED light.

1. Vehicle not moving, need to be moving

for brakes to apply.

2. No signal from brake light, test voltage

on RED wire.

3. Sensor set improperly,

see LEVELING SENSOR.

4. Bad connection on RED wire.

5. Blown stoplight fuse.

Appendix A: Trailer Brake Adjustment**

Brakes should be adjusted after the first 200 miles of

operation when the brake shoes and drums have “seated”

and at 3000 mile intervals, or as use and performance

requires. The brakes should be adjusted in the

following manner:

1. Jack up trailer and secure on adequate capacity

jack stands. Follow trailer manufacturers

recommendations for lifting and supporting the

unit. Check that the wheel and drum rotate freely.

WARNING

Do not lift or support trailer on any

part of the axle or the suspension system.

2. Remove the adjusting hole cover from the adjusting

slot on the bottom of the brake backing plate.

3. With a screwdriver or standard adjusting tool, rotate

the starwheel of the adjuster assembly to expand the

brake shoes. Adjust the brake shoes out until the

pressure of the linings against the drum makes the

wheel very difficult to turn.

Note: With drop spindle axles, a modified adjusting

tool with about an 80 degree angle should be used.

4. Then rotate the starwheel in the opposite direction

until the wheel turns freely with a slight lining drag.

5. Replace the adjusting hole cover and lower the

wheel to the ground.

6. Repeat the above procedure on all brakes.

WARNING

Never crawl under your trailer unless

it is resting on properly placed jack stands.

Follow the trailer manufacturers recommendations

for lifting and supporting the unit. Do not lift or place

supports on any part of the suspension system.

Dexter Axle.

Troubleshooting Chart

NOTE:

1. Always warm the trailer's brakes before

setting the power. Warm trailer brakes tend to

be more responsive than cold brakes. To warm

trailer brakes, drive a short distance (1/4 mile)

at 45 MPH with manual lever engaged enough

to cause trailer braking at a low level.

2. WARNING The power should never be set

high enough to cause trailer brakes to lock up.

Skidding trailer wheels can cause loss of

directional stability of trailer and tow vehicle.

3. The power may need to be adjusted for

different load weights and road conditions.

4. Not all trailer brakes will lock up due to

various conditions. However, inability to lock

up the brakes generally indicates the need for

an inspection to determine the cause.

5. When the power is set correctly you should

feel unified braking between the trailer and

tow vehicle.

6. When in doubt of the proper setting procedures

review the above steps starting at LEVELING

THE SENSOR through FINE TUNING or

consult your tow card included with your

brake control.
