REMOVAL
WARNING:
Never rest a steering column assembly on the steering
wheel with air bag (inflator) module face down and column
vertical. Otherwise personal injury may result.
1) Disconnect negative battery cable at battery terminal.
2) Disable air bag system. Refer to ªDISABLING AIR BAG SYS-
TEMº under ªSERVICE PRECAUTIONSº in Section 10B.
3) Remove steering wheel and contact coil and combination switch
assembly, if necessary. Refer to ªSTEERING WHEELº and
ªCONTACT COIL AND COMBINATION SWITCH ASSEMBLYº
in this section.
Perform the following procedure if not removing steering wheel
and/or combination switch.
ii) Turn steering wheel so that vehicle's front tires are at straight-
ahead position.
ii) Turn ignition switch to ªLOCKº position and remove key.
4) Remove steering column hole cover.
5) Disconnect all connectors for the following parts.

Contact coil and combination switch

Ignition switch
6) Make alignment marks on shaft joint and shaft (column side) for
a guide during reinstallation.
7) After removing bolt on column side of shaft joint and loosening
bolt on its lower shaft assembly side, move shaft joint to lower
shaft assembly side (in arrow direction in the figure).

CAUTION:
Don't tap wheel hub component by hammer or the like.
Otherwise, it will be broken.
NOTE:
When it is impossible to install wheel hub component by
hand, which means the inner race is out of alignment, re-
move wheel hub component once and reinstall it.
4) Install wheel bearing washer, and the install wheel bearing lock
nut.
5) Tighten wheel bearing lock nut to specified torque while turning
wheel hub by hand.

BRAKES 5-3
SUBSTANDARD OR
CONTAMINATED BRAKE FLUID
Improper brake fluid, mineral oil or water in the fluid
may cause the brake fluid to boil or the rubber compo-
nents in the hydraulic system to deteriorate.
If primary piston cups are swollen, then rubber parts
have deteriorated. This deterioration may also be evi-
denced by swollen wheel cylinder piston cups on the
drum brake wheels.
If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol
out of the system. Replace all rubber parts in the sys-
tem, including hoses. Also, when working on the
brake mechanisms, check for fluid on the linings. If ex-
cessive fluid is found, replace the linings.
If master cylinder piston seals are satisfactory, check
for leakage or excessive heat conditions. If condition
is not found, drain fluid, flush with brake fluid, refill and
bleed system.
The system must be flushed if there is any doubt as
to the grade of fluid in the system or if fluid has been
used which contained parts that have been subjected
to contaminated fluid.
DIAGNOSIS
ROAD TESTING BRAKES
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both
light and heavy pedal forces at various speeds to de-
termine if the vehicle stops evenly and effectively.
Also drive vehicle to see if it leads to one side or the
other without brake application. If it does, check the
tire pressure, front end alignment and front suspen-
sion attachments for looseness. See diagnosis chart
for other causes.
BRAKE FLUID LEAKS
Check the master cylinder fluid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low level indicates a leak in the
system. In such a case, check the entire brake system
for leakage. If even a slight evidence of leakage is
noted, the cause should be corrected or defective
parts should be replaced.
If fluid level is lower than the minimum level of reser-
voir, refilling is necessary. Fill reservoir with specified
brake fluid.
Brake fluid: Refer to reservoir tank cap.
CAUTION:
Since brake system of this vehicle is factory-
filled with brake fluid indicated on reservoir
tank cap, do not use or mix different type of
fluid when refilling; otherwise serious damage
will occur.
Do not use old or used brake fluid, or any fluid
from a unsealed container.
