INSTRUCTIONS FOR 10" BRAKES

II

BRAKE INSTALLATION

1. Brake Mounting Flange
To assure correct brake action, the mounting

flange must be square and concentric with the
axle spindle. A flange that is not properly
installed will contribute to rapid lining wear and
improper brake action.

The 10" DEMCO brake is designed to inter­change with existing equipment mounting on
flanges with (4) holes on 4" B.C. and a 3"
register diameter. Several manufacturers of­fer complete axles with flanges attached, or
you may choose to install flanges yourself.

Two types of cluster plates are used. One with
4" B.C. square pattern for conventional hubs
and one with 4" B.C. rectangular pattern for
new departure hubs.

Use a flange welding fixture to properly posi­tion the flange for welding. Bolt the flange to
the welding fixture securely with bolts.

Install the fixture (and flange) onto the spindle
and tighten spindle nut. If flange is being
installed on a round axle, rotate to insure
“wheel cylinder up” location when the axle is
installed.

Do not to make a continuous weld around the
flange. First, tack weld on all four sides be­tween the bolts. Follow this with a full weld up
each side of the axle. It is usually not advisable
or necessary to weld across the top and bottom
of the axle. The bottom of the axle is its most
highly stressed area and a weld at this point will
weaken the axle. Allow the axle, spindle, and
flange to cool before removing welding fixture.

2. Installing Brakes
Place the brake against spindle flange. In

mounting the brake, be sure the hydraulic
wheel cylinder is at the top. Brakes are also
marked as “RIGHTS” and “LEFTS”. The brake
designated as “LEFT” travels on the driver’s
side of the road.

3. Installing Brake Drum

When the brakes have been correctly as­sembled to the axle flanges, the hub and drum
assemblies may be mounted on the axle
spindle.

Two types of hubs may be used. The new
departure hub is greased for life and does not
need packing. The conventional hub however
is packed as follows.

Pack the inside bearing with suitable wheel
bearing grease. Force grease through and
around the rollers. Place the bearing in the hub
and install the grease seal flush with the end of
the hub using an arbor press or soft mallet.
Remove excess grease.

To avoid damage to bearing seal, lubricate
seal seat prior to putting on the hub. Grease,
pack and install the outer bearing on spindle.
Place flat washer and spindle nut on spindle.
Turn drum as you tighten nut. When a pro­nounced drag is felt in the bearings, stop
turning the hub and back off the nut one
complete turn and retighten with your fingers
(not any tighter). Now install the cotter pin and
dust cap.

Caution: Do not pack hub full of grease.
Excessive grease may leak into brake drums
causing brake failure.

Wheels may now be mounted on the trailers.

4. Adjusting Brakes
Self adjusting brakes must be adjusted the

first time only to assure having brakes the first
few times they are applied. Insert a brake
adjusting tool or screw driver 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 start to get a little brake
drag on the wheel. Do not over tighten the
adjusting nut. You can not back the nut off
unless you hold the adjusting shoe away from
the nut while turning it back.

ALWAYS ROTATE DRUM IN DIRECTION
OF FORWARD ROTATION ONLY.

Page 10

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.

5. Hydraulic Lines

Use care in forming tubing to avoid sharp
bends or kinks. Use double flare steel
tubing to assure tight leak-proof connec­tions. 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.

6. Bleeding the System

The first requirement for safe, sure hydrau­lic braking is the use of quality brake fluid.
Use only DOT-3 or DOT-4 brake fluid from
a sealed container.

If pressure bleeding equipment is available,
follow the manufacturer’s instruction in bleed­ing the system.

If system must be bled manually, pro­ceed as follows: Fill master cylinder with

fluid. Install bleeder hose on first wheel
cylinder to be bled (if tandem axle trailer,
bleed rear axle first).

Have loose end of hose submerged in brake
fluid in glass container to observe bubbling.

By loosening the bleeder screw located in
the wheel cylinder one half turn, the system
is open to the atmosphere through the pas­sage drilled in the screw. Pump actuator one
full stroke and hold. Now close the bleeder
valve, then release the lever. After the lever
is back, open the bleeder valve, pull the lever
forward and hold. This process must be
repeated until bubbles stop coming out of the
hose in the bottle. Be sure to close bleeder

screw securely.

Repeat bleeding operation at each wheel
cylinder. During the bleeding process, re­plenish the brake fluid, so the level does not
fall below the 1/2 full level in the master
cylinder reservoir. After bleeding is com­plete, fill the master cylinder reservoir and
secure the filler cap.

After the bleeding operation has been com­pleted, apply pressure to the system and
check the brake system for leaks.

WARNING: To Prevent

Serious Injury or Death

FAILURE TO FOLLOW THESE INSTRUCTIONS,
OR FAILURE TO PROPERLY MAINTAIN BRAKES
AFTER INSTALLATION, CAN RESULT IN LOSS
OF BRAKING ACTION. THIS CAN CAUSE PER­SONAL INJURY, DEATH OR PROPERTY DAM­AGE. ONLY PROFESSIONAL MECHANICS
SHOULD INSTALL BRAKE CLUSTERS. HAVE
YOUR BRAKES INSPECTED BY A PROFES­SIONAL MECHANIC AT LEAST ANNUALLY
AFTER INSTALLATION.
