BRAKE HOSE AND TUBING
INSPECTION OF BRAKE HOSE AND TUBING
Flexible rubber hose is used at both front brakes and
at the rear axle. Inspection of brake hoses should be
performed whenever the brake system is serviced and
every 7,500 miles or 12 months, whichever comes first
(every engine oil change). Inspect hydraulic brake
hoses for severe surface cracking, scuffing, or worn
spots. Should the fabric casing of the rubber hose be
exposed due to cracks or abrasions in the rubber hose
cover, the hose should be replaced immediately. Even-
tual deterioration of the hose can take place with
possible burst failure. Faulty installation can cause
twisting and wheel, tire or chassis interference. The steel brake tubing should be inspected periodi-
cally for evidence of physical damage or contact with
moving or hot components.
INSTALLATION OF BRAKE HOSE
Always use factory recommended brake hose to en-
sure quality, correct length and superior fatigue life.
Care should be taken to make sure that the tube and
hose mating surfaces are clean and free from nicks and
burrs. Front right and left side hoses are not
interchangeable. Connections should be correct and properly made.
Use new copper seal washers on all connections using
Banjo Bolts and tighten all fittings to their specified
torques. The flexible front hydraulic brake hose should al-
ways be installed on the vehicle by first attaching the
Banjo connector to the caliper assembly. Then bolt the
intermediate hose bracket to the strut assembly allow-
ing the bracket to position the hose to prevent twisting.
Attach the hose to the body bracket and steel brake
tubing. Tighten all fittings to specified torque. The
body bracket and hose end are keyed so that they will
only fit one way. Install rear brake hoses first to the trailing arm
tubes and then to the floor pan tubes. Minimize hose
twisting. Vehicles equipped with rear disc brakes have
brake hoses attached to the caliper on each side. The
brake hose should be first attached by the Banjo bolt to
the caliper and then secured to the hose bracket with
the retaining clip. The attach the steel brake tubing to
the hose fitting.
REPAIR AND INSTALLATION OF BRAKE TUB- ING
Only double wall 4.75mm (3/16 in.) steel tubing
should be used for replacement. Care should be taken
when replacing brake tubing, to be sure the proper
bending and flaring tools and procedures are used, to
avoid kinking. Do not route the tubes against sharp edges, moving components or into hot areas. All
tubes should be properly attached with recommended
retaining clips.
TYPES OF TUBING FLARES
Two different tubing flares (Fig. 13) are used on 93
M.Y. vehicles. On some ABS brake systems the tub-
ing connections made to the hydraulic assembly use
an ISO flare. All other ABS brake system compo-
nent, tubing connections are made using a double in-
verted flare. On non-ABS brake systems all
component tubing connections use only the double in-
verted flare. No ISO flares are used.
CAUTION: ALWAYS USE THE PROPER FLARING
TOOL AND PROCEDURE, FOR THE TYPE OF
BRAKE SYSTEM THAT IS BEING SERVICED TO IN-
SURE THE INTEGRITY OF THE HYDRAULIC SYS-
TEM.
TO REPAIR OR FLARE TUBING
Using Tubing Cutter, Special Tool C-3478-A or
equivalent, cut off damaged seat or tubing (Fig. 14).
Ream out any burrs or rough edges showing on in-
side of tubing (Fig. 15). This will make the ends of
tubing square (Fig. 15) and ensure better seating of
flared end tubing. PLACE TUBE NUT ON TUB-
ING BEFORE FLARING THE TUBING.
DOUBLE INVERTED TUBING FLARES.
To make a double inverted tubing flare (Fig. 13 &
16). Open handles of Flaring Tool, Special Tool
C-4047 or equivalent. Then rotate jaws of tool until
the mating jaws of tubing size are centered between
vertical posts on tool. Slowly close handles with tub-

DISC BRAKE CALIPER DISASSEMBLY
CLEANING AND INSPECTION
Check for piston fluid seal leaks (brake fluid in and
around boot area and inboard lining) and for any
ruptures of piston dust boot. If boot is damaged, or fluid
leak is visible, disassemble caliper assembly and in-
stall a new seal and boot,(and piston if scored). Refer to
procedures titled Disc Brake Caliper Disassembly. Check the caliper dust boot and caliper pin bushings
to determine if they are in good condition. Replace if
they are damaged, dry, or found to be brittle. Refer to
Cleaning And Inspection Of Brake Caliper. (1) Remove caliper from braking disc (See Brake
Shoe Removal). Hang assembly on a wire hook away
from braking disc, so hydraulic fluid cannot get on
braking disc (See Fig. 3 in Brake Shoe Removal). Place
a small piece of wood between the piston and caliper
fingers. (2) Carefully depress brake pedal to hydraulically
push piston out of bore. (Brake pedal will fall away
when piston has passed bore opening.) Then prop up
the brake pedal to any position below the first inch of
pedal travel, this will prevent loss of brake fluid from
the master cylinder. (3) If both front caliper pistons are to be removed,
disconnect flexible brake line at frame bracket after
removing piston. Plug brake tube and remove piston
from opposite caliper. Using the same process as above
for the first piston removal.
WARNING: UNDER NO CONDITION SHOULD AIR
PRESSURE BE USED TO REMOVE PISTON FROM
CALIPER BORE. PERSONAL INJURY COULD RE-
SULT FROM SUCH A PRACTICE.
(4) Disconnect brake flexible hose from the caliper.
To disassemble, mount caliper assembly in a vise
equipped with protective jaws.
CAUTION: Excessive vise pressure will cause bore
distortion and binding of piston.

See (Fig. 2) Power Distribution Center. Find the lo-
cation of the pump/motor relay in the (PDC). Remove
pump/motor relay by pulling upward and install by
pushing firmly into position. Do not twist the relay
when removing or installing it. See (Fig. 10) in the Relay And Warning Lamp Sec-
tion of this group, for the location of the Anti-Lock
system relay and the Yellow Lamp relay. Remove
the relay from the vehicle using the following proce-
dure. (1) Disconnect the wiring harness connectors from
the relays. Connectors are removed from the relays
by disengaging the connector locking tab from relay
and pulling strait off relay, do not twist. (2) Then remove the relay pack to inner fender at-
taching bolt.
INSTALL The Anti-Lock system and Yellow Lamp relay are
installed using the following procedure. (1) Mount the relay pack to the inner fender with
the anti-rotation tab on the bracket around lip of in-
ner fender hole (Fig. 10). (2) Install the relay pack to inner fender mounting
bolt and torque to 4 N Im (35 in. lbs.). (3) Connect the wiring harness connectors onto the
relays until the locking tabs on the connectors and
relays are fully engaged. Do not twist connectors when
installing them on the relays.
WHEEL SPEED SENSORS
INSPECTION
Inspect tone wheels (Fig. 3) for any missing or broken
teeth, this can cause erratic speed sensor signals.
Tone wheels should show no evidence of contact with
the wheel speed sensor. If contact was made, determine
cause and correct. Excessive runout of the tone wheels can cause erratic
wheel speed sensor signals. Replace assembly if runout
exceeds approximately 0.25 mm (0.010 inch).
FRONT WHEEL SPEED SENSOR
REMOVAL
(1) Raise vehicle and remove front wheel and tire
assembly. (2) Remove screw from clip (Fig. 4) that holds sensor
assembly grommet into fender shield. (3) Carefully, pull sensor assembly grommet from
fender shield. When removing grommet from
fender shield, do not pull on speed sensor cable. (4) Unplug speed sensor cable connector, from ve-
hicle wiring harness. (5) Remove the 2 screws (Fig. 4) that secure the
speed sensor cable, routing tube to the fender well. (6) Remove the 2 sensor assembly grommets from
the retainer bracket, on the strut damper (Fig. 4). (7) Remove speed sensor assembly to steering

(3) Clean the flywheel face with medium sandpa-
per (80-160 grade), then wipe the surface with min-
eral spirits. If the surface is severely scored, heat
checked, or warped, replace the flywheel.
CAUTION: Do not flat-machine the flywheel face.
The surface profile is tapered.
(4) The heavy side of the flywheel is indicated by a
daub of white paint near the outside diameter. To
minimize the effects of flywheel unbalance, perform
the following installation procedure: (a) Loose assemble the flywheel to the crank-
shaft. Use new flywheel attaching bolts which have
sealant on the threads. If new bolts are not avail-
able, apply Loctite sealant to the threads of the
original bolts. This sealant is required to prevent
engine oil leakage. (b) Rotate the flywheel and crankshaft until the
daub of white paint (heavy side) is at the 12 o'clock
position. (c) Torque flywheel attaching bolts to 95 N Im(70
ft. lbs.). Use a crisscross pattern when tightening
bolts.
(5) The disc assembly should be handled without
touching the facings. Replace disc if the facings show
evidence of grease or oil soakage, or wear to within
less than .38 mm (.015 inch) of the rivet heads. The
splines on the disc hub and transaxle input shaft
should be a snug fit without signs of excessive wear.
Metallic portions of disc assembly should be dry and
clean, and not been discolored from excessive heat.
Each of the arched springs between the facings
should not be broken and all rivets should be tight. (6) Wipe the friction surface of the pressure plate
with mineral spirits. (7) Using a straight edge, check clutch cover (pres-
sure plate) for flatness. The clutch cover (pressure
plate) friction area should be slightly concave, with
the inner diameter 0.02 mm to 0.1 mm (.0008 in. to
.0039 in.) below the outer diameter. It should also be
free from discoloration, burned areas, cracks,
grooves, or ridges. (8) Using a surface plate, test cover for flatness.
All sections around attaching bolt holes should be in
contact with surface plate within .015 inch. (9) The cover should be a snug fit on flywheel dow-
els. If the clutch assembly does not meet these re-
quirements, it should be replaced.
INSTALLATION
(1) Mount clutch assembly on flywheel,being care-
ful to properly align dowels and the alignment marks
made before removal. The flywheel side of the clutch
disc is marked for proper installation. If new clutch
or flywheel is installed, align cover balance spot as
close as possible to flywheel balance orange spot. Ap-
ply pressure to the alignment tool. Center the tip of the tool into the crankshaft and the sliding cone into
the clutch fingers. Tighten the clutch attaching bolts
sufficiently to hold the disc in position. (2) To avoid distortion of the clutch cover, bolts
should be tightened a few turns at a time, in a criss-
cross pattern, until they are all seated. Tighten bolts
to 28 N Im (250 in. lbs.) following a crisscross pattern
sequence. Remove clutch disc alignment tool. (3) Install transaxle. See group 21, Manual Tran-
saxle, for procedures.
RELEASE BEARING AND FORK
Remove the transaxle from the vehicle. See group
21 for removal and installation procedures.
REMOVAL AND INSTALLATION
(1) Remove clutch release shaft E-clip.
(2) Remove the clutch release shaft and then slide
the fork and bearing assembly off the bearing pilot. (3) Remove the fork from the bearing thrust plate.
(4) Examine the condition of the bearing. It is pre-
lubricated and sealed and should not be im-
mersed in oil or solvent. (5) The bearing should turn smoothly when held in
the hand under a light thrust load. A light drag
caused by the lubricant fill is normal. If the bearing
is noisy, rough, or dry, replace the complete bearing
assembly with a new bearing. (6) The bearing has a plastic sleeve pre-lubricated
at assembly. Wipe out the old grease. Refill the
sleeve cavities and coat the inner surface with mul-
tipurpose grease. If the liner is cracked or worn, re-
place the bearing assembly. (7) Check the condition of the spring clips. If the
clips are broken or distorted, replace the bearing as-
sembly. (8) Before assembling the fork, lubricate the
rounded thrust pads and the spring clip cavities with
multipurpose grease. (9) Assemble the fork to the bearing by sliding the
thrust pads under the spring clips. Be careful to
avoid distorting the spring clips. These clips prevent
the bearing thrust plate from rotating with the bear-
ing. (10) Slide the bearing and fork assembly onto the
input shaft bearing retainer. (11) Position the release shaft bushings in the
housing and install the release shaft. A small
amount of bearing grease between the release shaft
bushing and the shaft is beneficial but not required.
Install the retainer clip in the shaft groove near the
large bushing. (12) Install the release lever and retaining clip on
the outer end of the release shaft.

DURES.
Whenever a wiper motor malfunction occurs, first
verify that the wiper motor wire harness is properly
connected to all connectors before starting normal di-
agnosis and repair procedures. Refer to Wiper Motor
Diagnosis Chart (Fig. 9). The following is a list of general wiper motor sys-
tem problems, the tests that are to be performed to
locate the faulty part, and the corrective action to be
taken. These tests will cover both two speed and in-
termittent wipe functions.
TWO SPEED MOTOR FUNCTION TESTS
CONDITION: MOTOR WILL NOT RUN IN ANY SWITCH POSITION
PROCEDURE
(1) Check for a blown fuse in the fuse block. (a) If fuse is good, proceed to step 2.
(b) If fuse is defective, replace and check motor
operation in all switch positions. (c) If motor is still inoperative and the fuse does
not blow, proceed to step 2. (d) If replacement fuse blows, proceed to step 5.
(2) Place switch in LOW speed position.
(3) Listen to motor. If you cannot hear it running,
proceed to Step 4. If you hear it running, check motor
output shaft. If output shaft is not turning, replace
motor assembly. If it is turning, drive link to output
shaft or linkage is not properly connected. Replace
worn parts and/or properly connect drive link to the
motor output shaft. (4) Connect a voltmeter between motor terminal 3
and ground strap (Fig. 10). If there is no voltage or very
little voltage (less than one volt) present, move nega-
tive test lead from the ground strap to negative battery
terminal. (a) If an increase in voltage is noticed, the problem
is a bad ground circuit. Make sure the motor mount-
ing is free of paint and that nuts or bolts are tight. (b) If there is still no indication of voltage, the
problem is an open circuit in the wiring harness or
wiper switch. (c) If no more than 3 volts increase in voltage is
observed, the problem is a faulty motor assembly.
(5) Disconnect motor wiring connector and replace
fuse. (a) If fuse does not blow, motor is defective.
(b) If fuse blows, switch or wiring is at fault.
