Tie Down Drum Brake Kit for Electric Brakes - Manual (Page 2)

Lubricate and install the outer bearing on spindle. Place thurst washer and new locking tab washer if applicable)
and castle nut on spindle. Turn the brake drum as you the tighten spindle nut. When a pronounced drag is felt in
the bearings, back off the spindle nut one complete slot and install cotter pin or bend tab on locking tooth
washer (if aplicable) and dust cap. Caution: Do not over pack hub with grease. Excessive grease may leak into
brake drums causing brake failure. Install wheels at this time. Tighten wheel nuts to proper torque as
recommended by trailer or wheel manufacturer. Recheck lug torque after first 50 miles. Spin wheel at this time
to make sure the wheel rotates freely without wobble or drag.
4. Initial Adjustment of Brakes
Adjust the brakes before removing the jacks.
A. With trailer wheel off the ground and tire mounted. Remove
the rubber access hole plugs from the rear of the brake
backing plate.
B. Inserting a brake spoon or flat screwdriver through the
access hole(s), tighten the star adjuster while rotating the
wheel in the forward direction. NOTE: Always spin wheel in
the forward direction as if the trailer was traveling forward on
the road. Tighten the star adjuster until the wheel reaches a
point where the brake shoes start to engage.
C. Loosen the star adjustor one click at a time while turning the
wheel in a forward rotation. Continue adjusting one click at a
time until the wheel rotates with little effort.
D. Replace the rubber access hole plugs.
E. Repeat this procedure for all braking wheels.
5. Connect Elecrical Wires
Electric brake controllers are required to be used with electric brakes. Follow the manufacturers installation
and use instructions for setting up the brake controller with your tow vehicle and trailer.
Connect wiring separately to each brake. Magnet wires are not set up as “+” or “-”.
Electric Brakes are similar to drum brakes on an automobile; the difference is that instead of hydraulic pressure
actuating the brakes, an electromagnet activates the brakes. When power is given to the magnets, they are
attracted to the inside of the brake drum. The drag on the magnet moves the actuating arm and the brake shoes
are forced out to the inside of the brake drum hub.
NOTE: When using drum or disc brakes on tandem axle trailers, both axles must be installed with brakes,
Failure to install brakes on both axles will result in loss of braking performance, overheating of brakes & wheel
hub, and significantly reduce brake pad life.
