ON-VEHICLE SERVICE
WHEEL SPEED SENSOR OUTPUT VOLTAGE
MEASUREMENT
The EVOLUTION-V has the ABS-ECU connector terminal
arranged as shown at left. Accordingly, the terminals to
measure the output voltage of the wheel speed sensors are
different from EVOLUTION-V.
Follow the conventional procedures except these pick-out
terminals.

3. Rear speed sensor
4. Rear rotor (Refer to GROUP 27
REAR AXLE HUB.)NOTE
The front rotor and rear rotor are integrated with the drive
shaft and thus nonmaintainable.
Caution
When removing and installing the speed sensor and
rotor, use care not to allow the surfaces of the ball
piece and rotor at the end of the speed sensor to
be hit against a metal or other object, damaging
it.

PARKING BRAKE – Service Specifications / Lubricants / Special Tools36-2
The parking brake is designed as a drum-in-disc brake acting on the rear wheel. This brake is a little
different in construction between EVOLUTION-IV and EVOLUTION-V but much alike in the service procedure
of the parking brake section. In this group, therefore, the description is made only for EVOLUTION-IV.

PARKING BRAKE – On-vehicle Service36-3
ON-VEHICLE SERVICE
1. PARKING BRAKE LEVER STROKE CHECK
AND ADJUSTMENT
1-1 STROKE CHECK
Standard value: 5 – 7 notches
[Operating force of approx. 196 N {20 kgf}]
1-2 STROKE ADJUSTMENT
If the parking brake lever stroke is not the standard value,
adjust as described below.
(1) Loosen the adjusting nut at the floor console to release
the cable.
(2) Remove the adjustment hole plug, and then use a flat-tip
(–) screwdriver to turn the adjuster in the direction of
the arrow (the direction which expands the shoe) until
the disc cannot be rotated by both hands.
Return the adjuster five notches in the direction opposite
to the direction of the arrow. (Reference: shoe clearance
on one side 0.19 mm)
(3) Turn the adjusting nut to adjust the parking brake lever
stroke to the standard value. After adjusting, check that
there is no space between the adjusting nut and the
parking brake lever.
Check also that the adjusting nut is firmly held by the
nut holder.
Caution
If the parking brake lever stroke is below the standard
value and the braking is too firm, the rear brakes
may drag.
(4) After adjusting the parking brake lever stroke, jack up
the rear of the vehicle. Release the parking brake and
turn the rear wheels to check that the rear brakes are
not dragging.

REMOVAL SERVICE POINTS
AREAR BRAKE CALIPER ASSEMBLY REMOVAL
Remove the rear brake caliper assembly and support it with
wire or similar.
BSHOE HOLD-DOWN CUP REMOVAL
Extend the shoe and lining assembly, and remove the shoe
hold-down cup.
INSTALLATION SERVICE POINTS
AADJUSTER INSTALLATION
Install the adjuster so that the shoe adjusting bolt of left hand
wheel is attached towards the front of the vehicle, and the
shoe adjusting bolt of right hand wheel is towards the rear
of the vehicle.
BSHOE-TO-ANCHOR SPRING INSTALLATION
Install the shoe-to-anchor springs in the order shown in the
illustration.
Caution
The load on the respective shoe-to-anchor springs is
different, so the spring in the figure has been painted.
NOTE
The figure shows the left wheel; for the right wheel, the position
is symmetrical.
