clrp.
Reconnect the tie-rod ends to the steering knuckles,
tighten the castle nut ('96 -'97 models) or nut ('98 -
'OO models) to the specified torque, and install new
cotter plns.
NOTE: Before connecting the tie-rod ends, wipe off
any grease contamination from the ball joint tapered
section and threads.
CAUTION: Torquo the castle nut to the lower torque
sp€cification, then tighten it only tar enough to align
the slot with the pin hole. Do not align the nut by
loosening {,96 -'97 models only).

After installation, perform the following checks
. Start the engine, allow it to idle, and turn the
steering wheel from lock-tolock several times to
warm up the fluid. Check the gearbox for leaks
(see page 17-39).
. Adjust the front toe (see section 18).
. Check the steering wheel spoke angle. Adjust by
turning the right and left tie-rods, if necessary.

Brake System Rubber Parts and Brake Booster
Brake Boostet
Check brake operation by applying the brakes.
lf the brakes do not work properly, check the brake
booster, Replace the brake booster as an assembly
if it does not work properly or if there are signs of
leakage.
Piston Cup and Pressure Cup Inspeqtion
. Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leak-
age.
Replace the master cylinder as an assembly if
the pedal does not work properly or if there is
damage or signs of fluid leakage.
. Check for a difference in brake pedal stroke
between quick and slow brake applications.
Replace the master cylinder if there is a differ-
ence in oedal stroke.
Brake Hoses
Visually check for damage or signs of fluid leakage.
Replace the brake hose with a new one if it is dam-
aged or leaking.
Caliper Piston Seal and Piston Boots
Check brake ope.ation by applying the brakes.
Visually check for damage or signs of fluid leakage.
lf the pedal does not operate properly, the brakes
drag. or there is damage or signs of fluid leakage,
disassemble and inspect the brake caliper. Replace
the boots and seals with new ones whenever the
brake caliDer is disassembled.
Wheol Cylindor Piston Cup and Dust Cover
Check brake operation by applying the brakes.
Visually check for damage or signs of fluid leakage.
lf the pedal does not operate properly, the brakes
drag, or there is damage or signs of fluid leakage,
disassemble and inspect the wheel cylinder. lf nec-
essary, replace the wheel cylinder as an assembly.

Bleeding
CAUTION:
. Always use Genuine Honda DOT 3 Brake Fluid. Using 8
non-Honda brak€ fluid can cause corrosion and
docrea3e the life of the system.
. Make surs ||o dirt or other foteign matter is allowed
to contaminate the brake fluid,
. Do not spill brake lluid on the vehicle, it may damago
the paint; if brake lluid doos contac{ the paint, wash
it ofl imm€diately with water.
NOTE: The reservoir on the master cylinder must be at
the MAX (upper) level mark at the start of the bleeding
procedure and checked after bleeding each brake
caliper. Add fluid as required.
1. Make sure the brake fluid level in the reservoir is at
the MAX lupper) level line.
MAX {UPPER) LEVEL
CYLINDER
Have someone slowly pump the brake pedsl several
times, then apply steady Pressure.
Loosen the brake bleed screw to allow air to escape
from the system. Then tighten the bleed screw
securely.
Repeat the procedure for each wheel in the sequence
shown below until air bubbles no longer appear in
the fluid.
Refill the master cylinder reservoir to the MAX (up-
per) level line.

Brake Booster InsPection
FunctionalTest
1. With the engine stopped, depress the brake pedal
several times to deplete the vacuum reservoir, then
depress the pedal hard and hold it for 15 seconds lf
the pedal sinks' either the master cYlinder is
bypassing internally, or the brake system (master
cylinder. lines. modulator, proportioning control
valve, or caliPer) is ieaking.
2. Start the engine with the pedal depressed lf the
pedal sinks slightly, the vacuum booster is operating
normally. lf the pedal height does not vary, the
booster or check valve is faultY.
3. With the engine running. depress the brake pedal
lightly. Apply just enough pressure to hold back
automatic transmission creep. lf the brake pedal
sinks more than 25 mm (1.0 in.) in three minutes,
the master cvlinder is faulty. A slight change in
pedal height when the A'lC compressor cycles on
and off if normal. (The A/C compressor load
changes the vacuum available to the booster')
Leak Test
1. Depress the brake pedal with the engine running.
then stop the engine. lf the pedal height does not
vary while depressed for 30 seconds, the vacuum
booster is OK. lf the pedal rises. the booster is
faulty.
2, With the engine stopped, depress the brake pedal
several times using normal pressure When the
Dedal is first depressed, it should be low On con-
secutive applications, the pedal height should grad-
uallv rise. lf the pedal position does not vary, checK
the booster check valve.

Booster Check Valve Test
1. Disconnect the brake booster vacuum hose at the
booster.
2. Stan the engine and let it idle. There should be vac-
uum. lf no vacuum is available, the check valve is
not working properly. Replace the brake booster
vacuum hose and check valve, and retest.
