Mount the backplate to the spindle flange. In mounting
the brake, be sure the hydraulic wheel cylinder is at the
top. Brakes are also marked as “RIGHT” and “LEFT”. The
brake designated as “LEFT” travels on the driver’s side
of the road.

Use care in forming tubing to avoid sharp bends or kinks.
Use double flare steel tubing to assure tight leakproof
connections. This must be done by a certified brake
shop. Anchor all hydraulic lines at two foot intervals to
prevent chafing and vibration. Use hydraulic rubber
hose at points of flexing. Anchor hose ends to avoid
stress on tubing.
BRAkE ADJUStMEnt
Before removing the ground stand jacks, adjust the brakes.
Uni-servo brakes must be adjusted periodically to assure
having brakes when they are applied. Insert a brake adjusting
tool or a screwdriver into the slotted hole. With the handle up
and the bit down and against the adjusting nut, pull down on
the handle. While spinning the wheel adjust the cog wheel
up until you cannot rotate the wheel forward. Then back off
the adjusting wheel 20 notches.
ALWAYS ROTATE DRUM IN DIRECTION OF FORWARD
ROTATION ONLY.
BRAkE DRUM MAintEnAnCE
Brake drums must be reground if abnormal wear is found,
such as brake shoe hitting brake drum once lining is gone,
rivets hitting brake drums and or brake drums out of round.
NOTE: Maximum diameter allowed 13.060”
BRAkE SEt-UP
1. Attach brake line to master cylinder outlet. Make sure all
connections are tight.
2. Fill the master cylinder from a sealed container of DOT 3
or 4 brake fluid. A pressure type brake bleeder may be
used. If one is not available, you can bleed the system
manually as follows.
3. After the master cylinder has been filled, remove the flat
spring behind the emergency lever. Pull forward on the
lever to pump the master cylinder. Use short strokes until
bubbling stops in the master cylinder.
Bleed the rear axle first. Install bleeder hose on the bleeder
valve on the first wheel with other end of the hose in a
clear container partially filled with brake fluid.

WARNING:
To Prevent serious Injury or death
Saltwater, granular fertilizers and other corrosive materials are destructive to metal. To prolong the life of a braking
system used under corrosive conditions, we recommend that the actuator be flushed periodically with a high pressure
water hose. Be sure to re-grease bearings and oil all moving parts after the unit has dried. At the end of the season,
when unit is to be stored, remove the brake drums and clean inside the brakes. Pack wheel bearings before drum is
installed.
