tnstall the knuckle in the reverse order of removal'
and pay particular attention to the following items:
. Be careful not to damage the ball joint boots
when installing the knuckle.
. Torque all mounting hardware to the specified
torque valugs.
. Torque the castls nuts to the low€r torque specl-
fications, then tighten them only far enough to
align the slot with the pin hole. Do not align the
castle nut by loosening.
. lnstall new cotter pins into the castle nuts after
torquing.
. Avoid twistin0 the sensor wires when installing
the wheel ssnsor.
. Before installing the brake disc, clean the mating
surfaces of the front hub and the inside of the
brake disc.
. Before installing the wheel, clean the mating sur-
face ofthe brake disc and the inside of the wheel
. Check the front wheel alignment, and adjust it if
necessary (see page 18-4).

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.

Loosen the front wheel nuts slightly, then raise the
vehicle, and support it on safety stands. Remove
the front wheels.
Remove the brake pads (see page 19,8).
Inspect the disc surface for damage and cracks.
Clean the disc thoroughly and remove all rust.
Use wheel nuts and suitable plain washers to hold
the disc securely against the hub, then mount a dial
indicator as shown, and measure the runout at
10 mm (0.4 in) from the outer edge of the disc.

Disc Thickness and Parallelism
Inspection
1.Loosen the front wheel nuts slightly, then raise the
vehicle, and support it on safety stands. Remove
the front wheels.
Remove the brake pads (see page 19-8).
Using a micrometer, measure disc thickness at
eight points, approximately 45" apart and 10 mm(0.4 in) in from the outer edge of the disc.
Brake Dbc Thickn6s:
Standlrd: 20.9 - 21.8 mm (0.82 - 0.86 in)
Max. Refinishing Limit: 19.0 mm 10.75 inl
NOTE: Replace the brake disc if the smallest mea-
surement is less than the max. refinishinq limit.
Brake Disc Parallelism: 0.015 mm (0.fit06 in) max.
NOTE: This is the maximum allowable difference
between the thickness measurements.
lf the disc is beyond the service limit for parallelism,
refinish the brake disc with an on-car brake lathe.
The Kwik-Lathe produced by Kwik-Way Manufac-
turing Co. and the "Front Brake Disc Lathe" offered
by Snap-on Tools Co. are approved for this opera-
tion.
NOTE: See section 18 for brake disc reDlacement.

NOTEr
. The master cylinder pushrod-to-piston clearancemust be checked and adjustments made, if neces_sary, before installing the master cylinder.. ABS type is shown, conventional brake type is similar.
1. Set the special tool on the master cylinde. body; push
in the center shaft until the top of it contacts the endofthe secondary piston by turning the adjusting nut.
Without disturbing the center shaft's Dosition, installthe specialtool upside down on the booster.Install the master cylinder nuts, and tighten to thespecified torque.
Connect the booster in-line with a vacuum gauge O _
101 kPa (0 - 760 mmHg, 30 in.Hg) to the booster,sengine vacuum supply, and maintain an enginespeed that will deliver 66 kpa (500 mmHg, 20 in.Hg)vacuum.
With a feeler gauge. measure the clearance Detweenthe gauge body and the adjusting nut as shown.

NOTE: lf the clearance between the gauge bodyand adjusting nut is 0.4 mm (0.02 in), the pushrod-to-piston clearance is 0 mm. However, if the clear_ance between the gauge body and adjusting nut is0 mm, the pushrod-to-piston clearance is 0.4 mm(0.02 in) or more. Therefore, it must be adjusted andrechecked.
6. lf clearance is incorrect, loosen the star locknut, andturn the adjuster in or out to adjust.
NOTE;
. Adjust the clearance while the specified vacuumis applied to the booster.. Hold the clevis while adjusting.
Tighten the star locknut securely.
