GENERAL INFORMATION
BASE BRAKE SYSTEM COMPONENT DESCRIPTION
The standard brake system on this vehicle contains
the same components as brake systems described in
group 5 of the service manual, with the exception of
the brake pedal system and master cylinder. These
differences are mainly related to service procedures.
The major differences are as follows:
²Use of a torque shaft assembly to transfer brake
pedal travel to the power brake booster and master
cylinder on the left side of the vehicle
²A unique power brake booster and master cylin-
der.
Refer to the Base Brake System Component
Description in the General Information section of
group 5 for more information on components used in
the base brake system.
DESCRIPTION AND OPERATION
MASTER CYLINDER
The master cylinder used on this vehicle functions
the same as master cylinders used in other brake
systems. Refer to the Master Cylinder in the Descrip-
tion and Operation section of group 5 for more infor-
mation.
DIAGNOSIS AND TESTING
REAR DRUM BRAKE ADJUSTMENT
The rear drum brakes on front wheel drive vehicles
automatically adjust, when required, during the nor-
mal operation of the vehicle every time the brakes
are applied. Use the following procedure to test the
operation of the automatic adjuster.
Place the vehicle on a hoist with a helper in the
driver's seat to apply the brakes. Remove the access
plug from the adjustment slot in each brake support
plate to provide visual access of brake adjuster star
wheel. Disconnect parking brake cable from one side
of the vehicle at the equalizer under the vehicle at
the left frame rail. Working on the side of the vehicle
that parking brake cable is connected to, hold the
adjuster lever off the star wheel with a suitable tool,
and loosen the star wheel approximately 30 notches
in relation to the adjuster lever. This is to eliminate
the possibility that the brake is already properly
adjusted. Reconnect the parking brake cable and
repeat the procedure for the other side of the vehicle.

DRIVE PLATE MISALIGNMENT
Common causes of misalignment are:
²Heat warping
²Mounting drive plate on a dirty crankshaft
flange
²Incorrect bolt tightening
²Improper seating on the crankshaft shoulder
²Loose crankshaft boltsClean the crankshaft flange before mounting the
drive plate. Dirt and grease on the flange surface
may misalign the flywheel, causing excessive runout.
Use new bolts when mounting drive plate to crank-
shaft. Tighten drive plate bolts to specified torque
only. Over-tightening can distort the drive plate hub
causing excessive runout.

DIAGNOSIS AND TESTING (Continued)
ADJUSTMENTS
CLUTCH CABLE Ð LHD
The manual transaxle clutch release system has a
unique self-adjusting mechanism to compensate for
clutch disc wear. This adjuster mechanism is located
within the clutch cable assembly. The preload spring
maintains tension on the cable. This tension keeps
the clutch release bearing continuously loaded
against the fingers of the clutch cover assembly.
ADJUSTER MECHANISM FUNCTION CHECK Ð
LHD
(1) With slight pressure, pull the clutch release
lever end of the cable to draw the cable taut. Push
the clutch cable housing toward the dash panel (With
less than 20 lbs. of effort, the cable housing should
move 30-50mm.). This indicates proper adjuster
mechanism function. If the cable does not adjust,
determine if the mechanism is properly seated on the
bracket.
(2) If the adjust mechanism functions properly,
route cable to the transaxle.
(3) Insert cable into transaxle and through clutch
release lever. Ensure the cable is routed through the
smaller hole in the transaxle deck (Fig. 10).
(4) Pull down on cable and insert cable retaining
clip onto clutch cable end.
(5) Check clutch pedal position switch operation.
CLUTCH PEDAL POSITION SWITCH
The clutch pedal position switch is mounted to a
bracket located behind the clutch pedal. The switch
is held in place by four plastic wing tabs.
The clutch pedal position switch IS NOT adjust-
able. The pedal blade contacts the switch in the down
position.
