DRUM
DESCRIPTION
All 1500 models and early year production
2500/3500 are equipped with rear drum brake assem-
blies. They are two-shoe, duo-servo units with an
automatic adjuster mechanism.
Drum brake assemblies used:
²1500 models: 11 x 2.25 in.
²2500/3500 models: 12 1/8 x3.5 in.
The drum brakes are a semi-floating, self-energiz-
ing, servo action design. The brake shoes are not
fixed on the support plate. This type of brake allows
the shoes to pivot and move vertically to a certain
extent.
OPERATION
In operation, fluid apply pressure causes the wheel
cylinder pistons to move outward. This movement is
transferred directly to the brake shoes by the cylin-
der connecting links. The resulting brake shoe expan-
sion brings the lining material into contact with the
rotating brake drum.
Two forces affect the brake shoes once they contact
the drum. The first force being hydraulic pressure
exerted through the wheel cylinder pistons. And the
second force is the friction generated turning torque
of the rotating drum.

WHEEL CYLINDERS (Continued)

Page 304 of 2889

The drum forces both brake shoes to move in the
same direction of rotation. Servo action begins with
the primary brake shoe which begins to wedge (or
wrap) itself against the rotating drum surface. This
force is transmitted equally to the secondary brake
shoe through the adjuster screw and anchor pin. The
net result is that each shoe helps the other exert
extra force against the drum. It is servo action that
creates the wedging (or wrap) effect which produces
increased force on the drum braking surface.
All drum brake assemblies are equipped with a self
adjusting mechanism. The components forming the
mechanism consist of the: adjuster screw, adjuster
lever, actuating lever (11 inch brake), lever return
spring and the adjuster lever spring. The adjuster
lever on the 12 inch brake, is also equipped with a
lever and tension spring.
The adjuster mechanism performs two important
functions. First, is in maintaining proper brake shoe
operating clearance. And second, is to maintain brake
pedal height. The mechanism does so, by adjusting
the shoes in small increments to compensate for lin-
ing wear. The adjustment process is continuous
throughout the useful life of the brake lining.
The adjuster components are all connected to the
secondary brake shoes. Actual adjustment only
occurs during reverse brake stops. Secondary brake
shoe movement (during reverse stops), is what acti-
vates the adjuster components.
In operation, secondary shoe movement causes the
adjuster lever spring to exert pull on the lever. This
pivots the lever away from the adjuster screw teeth.
When the stop is completed and the brakes released,
the adjuster lever pivots back to a normal position. It
is during this return movement of the lever when
adjustment occurs. At this point, the lever comes
back into contact with the adjuster screw teeth as it
moves upward. The lever will then rotate the
adjuster screw one or two teeth as needed for adjust-
ment.
NOTE: The adjustment process requires a complete
stop to actually occur. Rolling stops will NOT acti-
vate the adjuster components. In addition, the
adjuster screws are left and right hand parts and
must NOT be interchanged.
DIAGNOSIS AND TESTING - BRAKE DRUM
The maximum allowable diameter of the drum
braking surface is indicated on the drum outer edge.
Generally, a drum can be machined to a maximum of
1.52 mm (0.060 in.) oversize. Always replace the
drum if machining would cause drum diameter to
exceed the size limit indicated on the drum.
BRAKE DRUM RUNOUT
Measure drum diameter and runout with an accu-
rate gauge. The most accurate method of measure-
ment involves mounting the drum in a brake lathe
and checking variation and runout with a dial indi-
cator.
Variations in drum diameter should not exceed
0.069 mm (0.0028 in.). Drum runout should not
exceed 0.18 mm (0.007 in.) out of round. Machine the
drum if runout or variation exceed these values.
Replace the drum if machining causes the drum to
exceed the maximum allowable diameter.
STANDARD PROCEDURE - BRAKE DRUM
MACHINING
The brake drums can be machined on a drum lathe
when necessary. Initial machining cuts should be lim-
ited to 0.12 - 0.20 mm (0.005 - 0.008 in.) at a time as
heavier feed rates can produce taper and surface
variation. Final finish cuts of 0.025 to 0.038 mm
(0.001 to 0.0015 in.) are recommended and will gen-
erally provide the best surface finish.
Be sure the drum is securely mounted in the lathe
before machining operations. A damper strap should
always be used around the drum to reduce vibration
and avoid chatter marks.
The maximum allowable diameter of the drum
braking surface is stamped or cast into the drum
outer edge.
CAUTION: Replace the drum if machining will cause
the drum to exceed the maximum allowable diame-
ter.
CLEANING
Clean the individual brake components, including
the support plate and wheel cylinder exterior, with a
water dampened cloth or with brake cleaner. Do not
use any other cleaning agents. Remove light rust and
scale from the brake shoe contact pads on the sup-
port plate with fine sandpaper.
INSPECTION
As a general rule, riveted brake shoes should be
replaced when worn to within 0.78 mm (1/32 in.) of
the rivet heads. Bonded lining should be replaced
when worn to a thickness of 1.6 mm (1/16 in.).
Examine the lining contact pattern to determine if
the shoes are bent or the drum is tapered. The lining
should exhibit contact across its entire width. Shoes
exhibiting contact only on one side should be
replaced and the drum checked for runout or taper.
Inspect the adjuster screw assembly. Replace the
assembly if the star wheel or threads are damaged,
or the components are severely rusted or corroded.

Discard the brake springs and retainer components
if worn, distorted or collapsed. Also replace the
springs if a brake drag condition had occurred. Over-
heating will distort and weaken the springs.
Inspect the brake shoe contact pads on the support
plate, replace the support plate if any of the pads are
worn or rusted through. Also replace the plate if it is
bent or distorted (Fig. 60).
ADJUSTMENT - REAR BRAKE DRUM
The rear drum brakes are equipped with a self-ad-
justing mechanism. Under normal circumstances, the
only time adjustment is required is when the shoes
are replaced, removed for access to other parts, or
when one or both drums are replaced.
Adjustment can be made with a standard brake
gauge or with adjusting tool . Adjustment is per-
formed with the complete brake assembly installed
on the backing plate.
ADJUSTMENT WITH BRAKE GAUGE
(1) Be sure parking brakes are fully released.
(2) Raise rear of vehicle and remove wheels and
brake drums.
(3) Verify that left and right automatic adjuster
levers and cables are properly connected.
(4) Insert brake gauge in drum. Expand gauge
until gauge inner legs contact drum braking surface.
Then lock gauge in position (Fig. 61).
(5) Reverse gauge and install it on brake shoes.
Position gauge legs at shoe centers as shown (Fig.
62). If gauge does not fit (too loose/too tight), adjust
shoes.
(6) Pull shoe adjuster lever away from adjuster
screw star wheel.(7) Turn adjuster screw star wheel (by hand) to
expand or retract brake shoes. Continue adjustment
until gauge outside legs are light drag-fit on shoes.
(8) Install brake drums and wheels and lower
vehicle.
(9) Drive vehicle and make one forward stop fol-
lowed by one reverse stop. Repeat procedure 8-10
times to operate automatic adjusters and equalize
adjustment.
NOTE: Bring vehicle to complete standstill at each
stop. Incomplete, rolling stops will not activate
automatic adjusters.

PARKING BRAKE
DESCRIPTION ± 2500/3500 WITH REAR DISC
BRAKES
The parking brakes are operated by a system of
cables and levers attached to a primary and second-
ary shoe positioned within the drum section of the
rotor.
The drum-in-hat design utilizes an independent set
of shoes to park the vehicle (Fig. 64).
DESCRIPTION - (1500 Models)(Early
2500/3500 models with rear drum brakes)
The parking brakes are operated by a system of
cables and levers attached to the rear brake shoes.
The rear drum brake shoes serve as the parking
brakes. The shoes make contact with the brake drum
surface by a cable and lever mechanism attached to
the secondary brake shoe.
The front parking brake cable is connected to the
parking brake pedal and to an intermediate cable.
The intermediate cable connects the front cable to
the rear cables.
The parking brake pedal assembly is mounted on
the driver side cowl panel. The front cable is directly
attached to the assembly. The pedal assembly con-
tains a spring loaded, torsion-type mechanism that
will hold the cable in the applied position and allow
the pedal to return. A rod used to release the torsion
mechanism and return the pedal to normal position.

OPERATION - 2500/3500 WITH REAR DISC
BRAKES
To apply the parking brake the pedal is depressed.
This creates tension in the cable which pulls forward
on the park brake lever. The lever pushes the park
brake shoes outward and into contact with the drum
section of the rotor. The contact of shoe to rotor parks
the vehicle.
A torsion locking mechanism is used to hold the
pedal in an applied position. Parking brake release is
accomplished by the hand release.
A parking brake switch is mounted on the parking
brake lever and is actuated by movement of the
lever. The switch, which is in circuit with the red
warning light in the dash, will illuminate the warn-
ing light whenever the parking brake is applied.
Parking brake adjustment is controlled by a cable
tensioner mechanism. The cable tensioner, once
adjusted at the factory, should not need further
adjustment under normal circumstances. Adjustment
may be required if a new tensioner, or cables are
installed, or disconnected.
OPERATION - (1500 models) (Early 2500/3500
models with rear drum brakes)
To apply the parking brakes, the pedal is
depressed. This pulls the rear brake shoe actuating
levers forward. As the actuating lever is pulled for-
ward, the parking brake strut or cam, exerts a linear
force against the primary brake shoe. This action
presses the primary shoe into contact with the drum.
Once the primary shoe contacts the drum, force is
exerted through the strut/cam. This force is trans-
ferred through the strut/cam to the secondary brake
shoe causing it to pivot into the drum as well.
A torsion locking mechanism is used to hold the
pedal in an applied position. Parking brake release is
accomplished by the hand release.
A parking brake switch is mounted on the parking
brake lever and is actuated by movement of the
lever. The switch, which is in circuit with the red
warning light in the dash, will illuminate the warn-
ing light whenever the parking brake is applied.
Parking brake adjustment is controlled by a cable
tensioner mechanism. The cable tensioner, once
adjusted at the factory, should not need further
adjustment under normal circumstances. Adjustment
may be required if a new tensioner, or cables are
installed, or disconnected.
