Backplate Installation

Mount the backplate to the spindle flange. In mount-

ing 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 driverís side of the road.

Brake Line Installation

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

twenty 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 al-

lowed 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.

RIGHT (Double Flare)

WRONG

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.
