5C-2 PARKING BRAKES
OPERATION (Fig. SC-1)
When pulled in the direction "A", the parking lever
presses the secondary shoe against the brake drum
using the lever/shoe joint "8" as a fulcrum and pushes
the strut in the direction
"C". The strut, in turn, presses
the primary shoe against the brake drum.
Counter
force "D" to the primary shoe is transmitted again to
Primary shoe
Parking cable guide
the secondary shoe through the fulcrum "8". The
secondary shoe contacts the
drum thereby producing
braking effect.
Clearance which may result from worn
parking brake shoe lining can be adjusted by turning
the adjusting screw. Refer to
"Parking Brake
Adjustment"
in this Section.

PARKING BRAKE LINING INSPECTION
(Fig. SC-8)
Check the shoe assemblies for wear by removing the
brake
drum rotor.
Replace the shoe assemblies, if the lining thickness is
less than 1.0 mm (0.039 in).

INSPECTION

of the rotor (drum).

PARKING BRAKE ADJUSTMENT
1. Adjustment of parking brake assembly
• Prior to lever stroke adjustment, adjust the rear
brake
shoe/rotor (drum) gap. Perform this
procedure
by loosening the adjust nut of the
equalizer.
a) Remove the adjusting hole plug (rubber) and
turn the shoe adjusting screw
downward with a
small screwdriver so that shoes will expand
until
they get into close touch with the rotor.
(Turn
down the adjusting screw notch by notch
until the rotor does not turn.)
b) Turn the adjusting screw in the opposite
direction (upward) until the rotor can
be turned
lightly. Standard
number of notches to turn
upward: 7 or 8.
Turn the rotor and make sure that there is no
brake dragging.
2. Adjustment of parking brake cable
a) Turn the equalizer nut so that the parking brake
lever travels 6
or 7 notches when pulled up with
a force of 30 kg (66 lb).
b) Make sure there is no brake dragging and
tighten the cable lock nut.
l~l Torque N·m (lb·in) 6 (52)
3. Break-in of parking brake shoe
• When poor braking effect possibly resulting
from insufficient break-in is felt, or just after
replacement
of parking brake shoe, be sure to
conduct break-in by driving vehicle as follows:
a) Forward 50 km/h (30 mph) x 400 m (About 30
seconds) with a lever pull force of 15 kg (33 lb),
and
b) Backward 10 km/h (6 mph) x 50 m (18 sec-
onds)
with a lever pull force of 15 kg (33 lb).
NOTE:
Break-in procedure must be performed under the
safety conditions and traffic rules.
• If braking effect still remains poor after the
above break-in,
wait for some time until
parking brake shoe cools
down and repeat the
procedures
a) and b) noted above.
• On completion of break-in, inspect parking
brake lever stroke, and
if the lever does not
come within the specified number of notches
when pulled up, readjust.
• Excessive brake-in may cause premature wear
of the parking brake lining.

DIAGNOSTIC TROUBLE CODE (DTC) 55
BRAKE SWITCH SHORT TO GROUND OR OPEN
This DTC does NOT flash the CHECK TRANS
indicator and does NOT set the BACKUP MODE.
Circuit Description:
• The brake switch is a switch on the brake pedal
that is used to provide the information: brakes
are
applied. This is used by different features:
cruise control, stop
light and Transmission
Control Module (TCM).
•
The TCM uses the information (brakes applied)
mainly to release the Torque Converter Clutch
(TCC).
•
The brake switch input is constantly connected to
battery when the pedal is pressed. TCM terminal
D9 is connected to Voltage.
• The brake switch input is opened when the pedal
is released.
TCM terminal D9 is grounded.

Diagnostic
Aids:
• This Diagnostic is not an electrical test done by
the TCM but a test between different information
("logic test").
• Detection conditions:
CD Brake seen as applied during an acceleration
from less than 10 Km/h to more than 60 Km/h
within 6 seconds.
@ After this acceleration the vehicle speed was
higher than 60 Km/h during at least 6
seconds.
@ No Malfunction: Output Speed (DTC11 ).
Downshift Protection (DTC62).
@ The conditions need to be present for at least
5
times during an ignition cycle.
• Action after the detection time: No action but, as
the brake is seen as applied, the TCC is never
applied.
• Recovery conditions: To recover, brake has to be
released.
