Apply power steering fluid to the surface of the spe-
cial tool. Set the new seal rings over the special tool
from the smaller diameter end of the tool, and
expand the seal rings. Do two rings at a time from
each end of the sleeve.
NOTE;
. Do not over-expand the seal ring. Installthe resin
seal rings with care so as not to damage them'
After installation, be sure to contract the seal
rings using the specialtool (sizing tool).
. There are two types of sleeve seal rings: black
and brown. Do not mix the different types of
sleeve seal rings as they are not compatible
Set the special tool in the grooves in the sleeve, and
set each ring in each groove securely.
NOTE: After installation, compress the seal rings
with your fingers temPorarilY

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.

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.

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.
