1 1 ANTI-LOCK BRAKE SYSTEM (ABS)
INSTALLATION
1. Install in the reverse order of removal.
Before installing the air cleaner assembly, igniter, and fuel filter:
(1) Add brake fluid and bleed air. (Refer to page 11—9.)
(2) Check each part for fluid leakage.
(3) Check the brake fluid level of both the master cylinder reservoir and hydraulic unit reservoir.
2. Tighten all bolts and nuts to the specified torque, referring to torque specifications.
3. After installation:
(1) The sealing reservoir cap (red) is installed on the new hydraulic unit to prevent the brake fluid
from leaking while shipping. Replace it with an original cap (black) after replacing the hydraulic unit.
(2) Check that the hydraulic unit operates properly by testing the pressure reduction. (Refer to page
11-95.)

WHEELS AND TIRES 1 2
WHEEL BALANCE
If a wheel becomes unbalanced or if a tire is replaced
or repaired, the wheel must once again be balanced
to within specification.
Maximum unbalance (at rim edge): g (oz)

13 inch-wheel 11 (0.39)
14 inch-wheel 10 (0.35)
15 inch-wheel 9 (0.32)

Caution
a) Do not use more than two balance weights
on the inner or outer side of the wheel, if
the total weight exceeds 100 g (3.5 oz), re-
balance after moving the tire around on the
rim.
b) Attach the balance weights tightly so that
they do not protrude more than 3 mm (0.12
in) beyond the wheel edge.
c) Select suitable balance weights for steel or
aluminum alloy wheels.
d)Do not use an on-car balancer on ATX
models. Use of this type of balancer may
cause clutch damage.
WHEEL MOUNTING
Tighten the lug nuts to the specified torque in a criss-
cross fashion.
Tightening torque:
88—118 N-m (9—12 m-kg, 65—87 ft-lb)
Caution
a) The wheel-to-hub contact surfaces must be
clean.
b) Never apply oil to the nuts, bolts, or wheels;
doing so might cause looseness or seizure
of the lug nuts.
86U12X-012
SPECIAL NOTE
Regarding wheels and tires:
1. Do not use wheels or tires other than the specified types.
2. Aluminum wheels are easily scratched. When washing them, use a soft cloth, never a wire brush.
If the vehicle is steam cleaned, do not allow boiling water to contact the wheels.
3. If alkaline compounds (such as salt water or road salts), get on aluminum wheels, wash them as
soon as possible to prevent damage. Use only a neutral detergent.
