9. Connect the brake line the wheel cylinder.
Tighten the line fitting to 11 ft. Ibs. (15 Nm).
10. Add brake fluid to the reservoir and leave the
wheel cylinder bleeder screw loose. Brake fluid will
start the flow into the wheel cylinder and may save
time when bleeding the brake system later.
OVERHAUL
u See Figures 99 thru lD8
Wheel cylinder overhaul kits may be available, but
often at little or no savings over a reconditioned
wheel cvlinder. It often makes sense with these com-
ponents to substitute a new or reconditioned part in-
stead of attempting an overhaul.
If no replacement is available, or you would prefer
to overhaul your wheel cylinders, the following pro-
cedure may be used. When rebuilding and installing
wheel cylinders, avoid getting any contaminants into
the system. Always use clean, new, high quality brake
fluid. If dirty or improper fluid has been used, it will
be necessary to drain the entire system, flush the
system with proper brake fluid, replace all rubber
components, then refill and bleed the system.

1. Remove the wheel cylinder from the vehicle
and place on a clean workbench.
2. First remove and discard the old rubber
boots, then withdraw the pistons. Piston cylinders are
equipped with seals and a spring assembly, all lo-
cated behind the pistons in the cylinder bore.
3. Remove the remaining inner components,
seals and spring assembly. Compressed air may be
useful in removing these components. If no com-
pressed air is available, be VERY careful not to score
the wheel cylinder bore when removing parts from it. Discard all components for which replacements were
supplied in the rebuild kit.
4. Wash the cylinder and metal parts in dena-
tured alcohol or clean brake fluid.
Never use a mineral-based solvent such as
gasoline, kerosene or paint thinner for clean-
ing purposes. These solvents will swell rub-
ber components and quickly deteriorate
them. 5. Allow the parts to air dry or use compressed
air. Do not use rags for cleaning, since lint will re-
main in the cylinder bore.
6. Inspect the piston and replace it if it shows
scratches.
7. Lubricate the cylinder bore and seals using
- clean brake fluid.

1. Make sure the parking brake cable is free and
is not frozen or sticking.
2. Apply the parking brake with 45 Ibs. (200 N) of
force while counting the number of notches. The de-
sired parking brake stroke should be 5-7 notches.
3. If adjustment is required, access the adjusting
nut from inside the floor console.
4. Loosen the locknut on the cable rod.
5. Rotate the adjusting nut to adjust the parking
brake stroke to the 5-7 notch setting. After making
the adjustment, check there is no looseness between
the adjusting nut and the parking brake lever, then
tighten the locknut.
*Do not adjust the parking brake too tight. If
the number of notches is less than specifica-
tion, the cable has been pulled too much and
the automatic adjuster will fail or the brakes
will drag.
6. After adjusting the lever stroke, raise the rear of
the vehicle and safely support. With the parking brake
lever in the released position, turn the rear wheels to
confirm that the rear brakes are not dragging.

heard should be 5-7 clicks. If the number of clicks
was not within that range, the system requires adjust-
ment.

1, Pull the parking brake lever with a force of ap-
prox. 45 Ibs. (200 N) and count the number of
notches. Standard value is: 5-7 notches.
The 45 lbs. (200 N) force of the parking brake
lever must be strictly observed.
2. If the parking brake lever is not the standard
value, adjust in the following manner:
a. Remove the inner compartment mat of the
floor console
b. Loosen the adjusting nut at the end of the
cable rod, freeing the parking brake.
c. With the engine idling, forcefully depress
the brake pedal five or six times and confirm that
the pedal stroke stops changing. If the pedal
stroke stops changing, the automatic-adjustment
mechanism is functioning normally, and the
clearance between the shoe and the drum is cor-
rect.
d. After adjusting the parking brake lever
stroke, safely raise and support the rear of the
vehicle and with the parking brake lever in the re-
leased position, turn the rear wheels to confirm
that there is no brake drag.

The 4-Wheel Anti-lock Brake System (ABS) is an
electronically operated, all wheel brake control sys-
tem. Major components include the vacuum power
brake booster, master cylinder, the wheel speed sen-
sors, the Hydraulic Control Unit (HCU), Anti-lock
control unit, a relay, and on the AWD Galant, a G sen-
sor.
The system is designed to retard wheel lockup
during periods of high wheel slip when braking. Re-
tarding wheel lockup is accomplished by modulating
fluid pressure to the wheel brake units. When the
control unit detects a variation in voltage across the
wheel speed sensors, the ABS is activated. The con-
trol unit opens and closes various valves located in-
side the HCU. These valves, called dump and isola-
tion valves, modulate the hydraulic pressure to the
wheels by applying and venting the pressure to the
brake fluid circuits.
PRECAUTIONS
l Certain components within the Anti-Lock Brake
System (ABS) are not intended to be serviced or re-
paired individually. Only those components with re- !
moval and installation procedures should be ser-
viced.
0 Do not use rubber hoses or other parts not
specifically specified for an ABS system. When using
repair kits, replace all parts included in the kit. Partial
or incorrect repair may lead to functional problems
and require the replacement of components.
l Lubricate rubber parts with clean, fresh brake
fluid to ease assembly. Do not use lubricated shop air
to clean parts; damage to rubber components may re-
sult.
l Use only specified brake fluid from an un-
opened container.
l If any hydraulic component or line is removed
or replaced, it may be necessary to bleed the entire
system.
l A clean repair area is essential. Always clean
the reservoir and cap thoroughly before removing the
cap. The slightest amount of dirt in the fluid may plug
an orifice and impair the system function. Perform re-
pairs after components have been thoroughly
cleaned; use only denatured alcohol to clean compo-
nents. Do not allow ABS components to come into
contact with any substance containing mineral oil;
this includes used shop rags.
l The Anti-Lock control unit is a microprocessor
similar to other computer units in the vehicle. Ensure
that the ignition switch is
OFF before removing or in-
stalling controller harnesses. Avoid static electricity
discharge at or near the controller.
l If any arc welding is to be done on the vehicle,
the control unit should be unplugged before welding
operations begin.

The diagnosis of the ABS system is rather complex
and requires quite a few special tools including scan tools, special test harnesses and other special and
expensive tools. Alternative methods and common
sense can be substituted, however, We at Chilton feel
that it is beyond the scope of the average do-it-your-
selfer. If you experience the amber ANTI LOCK light
on in the instrument cluster of your vehicle, check the
fluid level in the master cylinder first. Low fluid level
will usually illuminate the red BRAKE lamp in the in-
strument cluster as well as, but not always, the amber
ANTI LOCK lamp in the instrument cluster. The low
fluid level could indicate a leak, but sometimes just
indicates low, worn brake linings that have caused the
caliper pistons and wheel cylinders to extend further,
and thus using more fluid to exert force on them. In-
spect the brake system for hydraulic fluid leaks and
also inspect the brake linings for excessive wear.
