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.
) See Figures 116 thru 123
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.
