Rear Disc Rotor
BRAKE
6. Rear Disc Rotor
A: REMOVAL
1) Lift-up the vehicle, and then remove the rear
wheels.
2) Release the parking brake.
3) Remove the two mounting bolts, and remove the
rear disc brake assembly.
4) Suspend the rear disk brake assembly so that
the hose is not stretched.
5) Remove the rear disk brake rotor.
NOTE:
If the disc rotor is difficult to remove, try the follow-
ing two methods in order.
(1) Turn the adjusting screw using a flat tip
screwdriver until the brake shoe moves ade-
quately away from the disc rotor.
(2) If it is difficult to remove the disc rotor from
the hub, drive an 8 mm bolt into the threads B of
the rotor, then remove the rotor.
B: INSTALLATION
1) Install in the reverse order of removal.
Tightening torque:
66 N·m (6.7 kgf-m, 48.7 ft-lb)
2) Adjust the parking brake. JUSTMENT, Parking Brake Assembly (Rear Disc
Brake).>
C: INSPECTION
1) Check the rear wheel bearing play and axle hub
runout before inspecting the disc rotor runout limit.
Bearing.>
2) Secure the disc rotor by tightening the five wheel
nuts.
3) Set a dial gauge 10 mm (0. 39 in) inward from
the disc rotor outer circumference. Rotate the disc
rotor to check runout. If the disc rotor runout ex-
ceeds the limit, replace with a new disc rotor. After
grinding, check disk rotor thickness according to
step 4).

2. Wheel Alignment
A: INSPECTION
Check the following items before performing the wheel alignment measurement.
Check items before measuring wheel alignment:
•Tire inflation pressure
•Uneven wear of RH and LH tires, or difference of sizes
•Tire runout
•Excessive play and wear of ball joint
•Excessive play and wear of tie rod end
•Excessive play of wheel bearing
•Right and left wheel base imbalance
•Deformation and excessive play of steering link
•Deformation and excessive play of suspension parts
Check, adjust and measure the wheel alignment in accordance with the procedures indicated in the figure.

POWER ASSISTED SYSTEM (POWER STEERING)
1. NOISE & VIBRATION
CAUTION:
Do not keep the relief valve operated over five seconds at any time or inner parts of the oil pump may
be damaged due to rapid increase of fluid temperature.
NOTE:
•A screeching noise may be heard immediately after the engine start in extremely cold conditions. In this
case, if the noise goes off during warm-up there is no abnormal function in the system. This is due to the fluid
characteristics in extremely cold condition.
•The oil pump normally makes a small whining noise due to its mechanism. Even if a noise is heard when
steering wheel is turned at stand still, there is no abnormal function in the system provided that the noise
eliminates when the vehicle is driving.
•When turning the steering wheel with the brake applied when the vehicle is parked, a screeching noise
may be generated by the brake disc and pads. This is not a fault in the steering system.
•There may be a small vibration around the steering devices when turning the steering wheel at standstill,
even though the component parts are operating properly.
Hydraulic systems are likely to generate this kind of vibration as well as working noise and fluid noise be-
cause of combined conditions, i.e., road surface and tire surface, engine speed and turning speed of steering
wheel, fluid temperature and braking condition.
These conditions do not indicate a problem in the system.
Confirm vibration for an AT model, by applying the parking brake on a concrete surface, shifting into the “D”
range, and turning the steering wheel repeatedly from slow to rapid, step by step.
Tr o u b l e P o s s i b l e c a u s e C o r r e c t i v e a c t i o n
Hiss noise (continuous)
While engine is running.
Relief valve emits operating sound when steering wheel is
completely turned in either direction. (Do not keep this
condition over five seconds.)
Normal
Relief valve emits operating sound when steering wheel is
not turned. This means that the relief valve is defective. Replace the oil pump.

Check the clearance.
Correct if necessary.
