FIG. 10—Parking Brake Control Assembly

With Manual Release—Typical

power unit with mounting bracket is

riveted to the control assembly. The

vacuum actuated piston within the

unit is connected by a rod to the

upper end of the release lever (Fig. 9).

The lower end of the release lever ex-

tends out for alternate manual release
in the event of vacuum power failure

or for optional manual release at any

time.

Hoses connect the power unit and

the engine manifold to a vacuum re-

lease valve in the transmission neutral

safety switch.
The anti-skid control system con-

sists of three major components (Fig.

39).
Mechanically driven electromag-

netic sensors at each rear wheel; an

electronic control module mounted

under the glove box; a vacuum pow-

ered actuator attached to a bracket on

the inside of the right front frame rail

under the toe board.

The sensors consist of steel rings

having teeth on their outer diameters,

pressed on each axle shaft just out-

board of the wheel bearing. The teeth

rotate past corresponding teeth on the

inside diameter of stationary steel

rings mounted in the bearing retain-

ers.
Also mounted in the retainers, are

ring-shaped permanent magnets and

coils of wire. Two wires from each

sensor connect the sensors to the con-

trol module.

The control module consists of solid

state electronic components sealed in

a container. It is connected to the sen-

sors and to a solenoid on the actuator.

The actuator is similar to a vacuum

brake booster and consists of three

parts.
A chamber divided by a vacuum

suspended diaphragm; a hydraulic cyl-

inder connected to the diaphragm; and

a solenoid connected electrically to the

control module.

IN-VEHICLE ADJUSTMENTS AND REPAIRS

After any brake service work, ob-

tain a firm brake pedal before moving

the vehicle. Riding the brake pedal

(common on left foot application)

should be avoided when driving the

vehicle.

BRAKE SHOE ADJUSTMENTS—

DRUM BRAKES

The hydraulic drum brakes are

self-adjusting and require a manual

adjustment only after the brake shoes

have been relined, replaced, or when

the length of the adjusting screw has

been changed while performing some

other service operation. The manual

adjustment is performed with the

drums removed, using the tool and the

procedure detailed below.

When adjusting the rear brake

shoes,
check the parking brake cables

for proper adjustment. Make sure that

the equalizer operates freely.
To adjust the brake shoes:

1.
Use Rotunda Tool HRE 8650,

(Fig. 11) to determine the inside diam-

eter of the drum braking surface.

2.
Reverse the tool as shown in Fig.

11 and adjust the brake shoe diameter

to fit the gauge. Hold the automatic

adjusting lever out of engagement

while rotating the adjusting screw, to

prevent burring the screw slots. Make

sure the adjusting screw rotates freely.

If necessary, lubricate the adjusting

screw threads with a thin, uniform

coating of MIC-100-A.

3.
Rotate Tool HRE 8650 around

the brake shoes to be sure of the set-

ting.

4.
Apply a small quantity of high

temperature grease to the points

where the shoes contact the backing

plate, being careful not to get the lu-

bricant on the linings.

5. Install the drums. Install Tinner-

man nuts and tighten securely.

6. Install the wheels on the drums
and tighten the nuts to specification.

7.
Complete the adjustment by

applying the brakes several times with

a minimum of 50 lbs pressure on the

pedal while backing the vehicle. After

each stop the vehicle must be moved

forward.

8. After the brake shoes have been

properly adjusted, check the operation

of the brakes by making several stops

while operating in a forward direction.

WHEEL CYLINDER REPAIR-

DRUM BRAKE

Wheel cylinders should not be di-

sassembled unless they are leaking or

unless new cups and boots are to be

installed. It is not necessary to remove

the brake cylinder from the backing

plate to disassemble, inspect, or hone

and overhaul the cylinder. Removal is

necessary only when the cylinder is

damaged or scored beyond repair.procarmanuals.com

tube.
In some instances the column

will shift into proper alignment when

the toe plate attaching nuts are loos-

ened. (Alignment is acceptable if a

.010 inch feeler blade can be passed

freely, completely around the area be-

tween the outer diameter of the steer-

ing shaft and the shift tube.) if the

misalignment condition can be attrib-

uted to this area, file or ream the dash

panel holes for greater clearance. If

the alignment is maintained after the

toe plate nuts and toe plate to column

clamp bolt and nut are torqued to the

8-12 ft-lb specification, no further ad-

justment is necessary.

4.
Remove instrument panel lower

trim panel. Vehicles equipped with a

combination radio stereo tape player

will require removal of the radio and

tape player assembly in order to gain

access to the upper R.H. steering col-

umn support bracket bolt.

5.
Loosen the seven bolts at the

steering column support bracket and

brake pedal support bracket.
6. Install a 3/16 inch diameter rod

spacer in the flex coupling to assure

proper clearance between upper and

lower steering shaft.

7.
Raise the vehicle, remove the

transmission splash shield, and visual-

ly align the column to center the

steering shaft in the column. Tighten

two toe plate attaching nuts sufficient-

ly to hold the column alignment (two

persons may be required for this oper-

ation).

8. Lower the vehicle.

9. Check the clearance between the

steering column support bracket and

the instrument panel bracket. It may

be necessary to add shims (Part Num-

ber MK-3054-A .060 inch thick, or

C3AZ-3054-A, .113 inch thick) be-

tween the support bracket and the in-

strument panel bracket to prevent

movement of the column when the

support bracket bolts are tightened.

10.
Loosen the two toe plate at-

taching nuts previously tightened. Re-

check steering column alignment. In
some instances it may be necessary to

enlarge the holes in the dash panel in

order to obtain proper column align-

ment.

11.
With the column properly al-

igned, torque the four toe plate at-

taching nuts to 4-9 ft-lbs.

12.
Torque the toe plate to steering

column clamp bolt to 3-5 ft-lbs.

13.
Recheck steering shaft to shift

tube alignment. A 0.10 inch feeler

blade should pass freely, completely

around the area between the outer di-

ameter of the steering shaft and shift-

er tube.

14.
Raise the vehicle.

15.
Adjust transmission shift link-

age.

16.
Install transmission splash

shield.

17.
Lower the vehicle.

18.
Install the radio stereo tape

player if so equipped.

19.
Install instrument panel lower
