PARKING BRAKE SYSTEM 5D-11
Inspection and Repair
Brake Lining Inspection
Check the shoe assemblies for wear by removing the
brake drum.
Replace the shoe assemblies if the lining thickness is
less than 1.0 mm (0.039 in).
Minimum limit: 1.0 mm (0.039 in)

Parking Brake Adjustment
NOTE: All brakes are self-adjusting. Brakes are
adjusted by repeated stepping on the brake pedal.
(After stepping on the pedal and releasing it, the rea
r
brake auto-adjuster produces a clicking sound. The
same operation should be repeated until the sound
disappears.)
Take the following steps after overhauling the rea
r
brake assembly.
1. Move the parking brake lever to its fully released position.
2. Parking brake cable must be loosened sufficiently.
(Loosen the adjust nut.)
3. Repeat stepping on the brake pedal firmly, and releasing it until the clicking sound can no longe
r
be heard.
If the difference between the brake drum inside
diameter and the brake shoes external diameter is
adjusted to be 0.4 mm (0.0157 in), the number o
f
times for depressing the brake pedal can be
reduced.

4. Remove the drum. Measure the brake drum inside
diameter and the brake shoes external diameter.
Total shoe clearance: 0.4 mm (0.0157 in)
If incorrect, readjust the brake shoe clearance.
5. Rotate the adjust nut of hand brake lever until all slack disappears from the cable. Set the adjust
nut.
6. After the rear brake shoe/drum gap has been adjusted, perform parking brake cable adjustment.
7. Turn the adjusting nut so that the parking brake lever travels 6 −9 notches (Bucket Seat) or 8 −14
notches (Bench Seat) when pulled up with a force
of 294 N (30 kg/66 lb).
8. Make sure there is no brake dragging.

Engine Management – V6 – General Information Page 6C1-1–15

W hen the cruise control ON-OFF switch, located on the right hand side of the dash panel, is pressed, the PIM, on
receiving the input from the switch, turns on the cruise ON-OFF switch warning lamp to inform the user that the cruise
control has been engaged.
W hen the cruise control switch assembly is pressed to SET/COAST, the PIM on receiving the input, sends a signal via
the serial data bus to the ECM. Providing the pre-conditions for cruise control operation have been met, the ECM
activates cruise control and commands the PIM to turn on the instrument cluster cruise set warning lamp, to inform the
user that cruise control is active. The ECM receives all the various inputs required to maintain the correct speed and then
controls the throttle plate depending on the load on the engine (ascending or descending hills, etc).
The cruise control is deactivated by either pressing the brake pedal, clutch pedal, cruise CANCEL or by the cruise control
ON-OFF button. In each of these instances, the ECM receives an input when any of these switches are activated. For
further information on the cruise control system, refer to 8C Cruise Control – HFV6.
3.7 Brake Torque Management
Brake torque management places limits on engine torque when the brakes are applied, regardless of the accelerator
pedal position (APP). The conditions under which brake torque management occur are as follows:
• The accelerator has been depressed before the brakes are applied,
• The brakes are applied and the ECM receives an input from the stop lamp switch,
• Vehicle speed is greater than 5 km/h,
• Engine speed is greater than 1200 rpm and
• Conditions exist for greater than 2.5 seconds.
W hen brake torque management has been implemented, the torque is reduced by altering the throttle plate opening by
25%. The ECM will monitor the rate at which the vehicle is slowing and adjust the throttle plate opening accordingly.
3.8 Emission Control Systems
Evaporative Emission Control System
The evaporative emission control system used is the
activated carbon (charcoal) canister storage method. Fuel
vapour is drawn from the fuel tank into the canister where it
is held by the activated carbon until the ECM commands the
evaporative emission (EVAP) purge solenoid valve to open.
The ECM energises the EVAP purge solenoid valve by
applying a pulse width modulated (PW M) ground to the
EVAP purge solenoid valve control circuit.
