Lubricate and install the outer bearing on spindle. Place thurst washer and new locking tab washer (if aplicable)
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 Hydraulic Lines
The use of double flare steel tubing will assure tight leak proof connections. Anchor all hydraulic lines at two foot
intervals to prevent chafing and vibration.
6. Bleeding the Brake System
Use only DOT-3 heavy duty fluid. Do not re-use brake fluid. Do not use any other type of brake fluid other than DOT-3.
If pressure bleeding equipment is available, follow the manufacturer’s instruction in bleeding the system.
(6a) Use only DOT-3 heavy-duty hydraulic fluid in the actuator. If using a pressure type brake bleeder to bleed
brakes. (This type of brake bleeder is available at your local automotive jobber.) Follow manufacturer’s directions.
If manually bleeding the brakes using a heavy-duty flat blade screwdriver inserted in the hole provided on top of
the actuator near the front. Insert the screwdriver and use a pumping action to activate the master cylinder in
order to bleed the brakes.
To bleed master cylinder and brakes, install bleeder hose on first wheel cylinder to be bled; bleed closest axle
first, and the closest brake on that axle first. Use a loose end of hose from the bleeder valve submerged in a glass
container of brake fluid to observe bubbling (hose must be submerged into clean brake fluid to keep air from
traveling back into the brake cylinder).
Loosen the bleeder screw located in the wheel cylinder one turn, the system is now open to the atmosphere. The
bleeding operation for that brake is complete when bubbling stops. Be sure to tighten bleeder screw securely.
