and push in the piston while letting some brake fluid
escape.
(c) Install the anti±squeal shim on each pad.
HINT:
wPlace the pad wear indicator facing downward.
wApply disc brake grease to inner side of the antisqueal.

CIRCUIT DESCRIPTION
The speed sensor detects the wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
both the ABS and TRAC control systems. The front and rear ro-
tors each have 48 serrations. When the rotors rotate, the mag-
netic field emitted by the permanent magnet in the speed sensor
generates an AC voltage. Since the frequency of this AC volt-
age changes in the direct proportion to the speed of the rotor,
the frequency is used by the ECU to detect the speed of each
wheel.

Detection of any of conditions (1) through (3):
(1) At vehicle speed of 10 km/h (6 mph) or
more, pulses are not input for 5 sec.
(2) Momentary interruption of he vehicle
speed sensor signal occurs at least 7
times in the time between switching the
ignition switch ON and switching it OFF.
(3) Abnormal fluctuation of speed sensor sig±
nals with the vehicle speed 20 km/H (12
mph) or more.
Speed sensor signal is not input for about 1
sec. while the left front and right rear speed
sensor signals are being checked with the IG

wDrive the vehicle at approx. 50 km/h (30 mph) on a safe,
level and dry road.
wWith the parking brake button pushed in, pull on the
lever with 88 N (9 kgf, 20 lbf) of force.
wDrive the vehicle for approx. 400 meters (1/4 mile) in this
condition.
wRepeat this procedure 2 or 3 times.
wCheck parking lever travel.
If necessary, adjust the parking brake.

16. INSPECT STEERING LINKAGE
(a) Check the steering wheel freeplay.
Maximum freeplay:
30 mm (1.18 in.)
With the vehicle stopped and pointed straight ahead, rock the
steering wheel gently back and forth with light finger pres-
sure.
(b) Check the steering linkage for looseness or damage.
Check that:
wTie rod ends do not have excessive play.
wDust seals and boots are not damaged.
wBoot clamps are not loose.
17. INSPECT SRS AIRBAG
Driver Airbag:
Visually inspect the steering wheel pad (airbag and inflater).
wUse the diagnosis check to check if there are
abnormalities.
wCheck that there are no cuts, cracks or noticeable color
changes on the surface of the steering wheel pad or in
the center groove of the pad.
wRemove the steering wheel pad from the vehicle and
check the wiring and steering wheel for damage and
corrosion due to rusting, etc.
If necessary, replace the steering wheel pad. MA±12
