Inspect piston seal ring. Replace if necessary .
Ensure brake band is correctly
positioned .
Rotate
output shaft if necessary.
Install servo piston fitter in servo bore.
Install apply rod, round end toward band,
return
spring and piston assembly.
Install the tool with offset to rear of case .
Compress servo
piston seal ring, using fitter
while tightening the tool screw.
Install servo piston retaining ring .
Remove
tool.
Adjust the brake band by tightening the servo
adjusting screw
to 4.5 N-m torque. Be certain
the lock nut
is loose, then back-off the screw
five turns exactly. Hold piston sleeve with
wrench and tighten lock nut to
18.5 N-m torque.
Be certain the adjusting screw does not turn.

8 -172 CHASSIS ELECTRICAL
CRUISE CONTROL
GENERAL DESCRIPTION
The circuit consists of the starter switch, cruise main switch, control switch, control unit, pump and actuator,
brake switch, clutch switch (M/T),
mode switch (Nf), vehicle speed sensor (incorporated into speedometer),
and indicator lights.
The cruise
control system keeps the vehicle running at a fixed speed until a signal canceling this speed is
received.
When the vehicle is in a running state with the main switch on, the battery voltage is applied to the control
unit. When a signal from the control switch is input into the control unit, while the vehicle is in this state, the
cruise control actuator is activated
to operate the system.
Also,
while the system is operating, the "AUTO CRUISE" indicator light in the instrument panel cluster lights
up.
Refer
to Section 98 "CRUISE CONTROL" for detail.
