PARKING BRAKE SHOE
• Install the adjuster so that the threaded part expands when rotating
it in the direction shown by the arrow.
• Shorten adjuster by rotating it in the opposite direction.
NOTE:
After replacing the shoes or disc rotors, or if parking brake does not
function properly, perform the break-in operation as follows.
1.
Adjust the parking brake pedal stroke to specification. Refer to
.
2.
Perform the parking brake break-in operation by driving the vehicle forward under the following conditions:
• Maintain vehicle speed 40 km/h (25 MPH) moving forward.
• Apply the parking brake pedal with an operating force of 196 N (20.0 kg-f, 44.1 lb-f).
• Apply the parking brake pedal for a period of 30 seconds before releasing.
CAUTION:
• To prevent the linings from getting too hot, allow a cool off period of approximately 5 minutes
after every break-in operation.
• Do not perform excessive break-in operations, because it may cause uneven or early wear of the
linings.

1.
GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2
2.
CHECK DTC
1.
Check DTC.
2.
Perform the following procedure if DTC is displayed.
-
Record DTC and freeze frame data.
-
Erase DTC.
-
Study the relationship between the cause detected by DTC and the symptom described by the customer.
3.
Check related service bulletins for information.
Is any symptom described and any DTC detected?
Symptom is described, DTC is displayed>>GO TO 3
Symptom is described, DTC is not displayed>>GO TO 4
Symptom is not described, DTC is displayed>>GO TO 5
3.
CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR” mode and check real time diagnosis results.
Verify relationship between the symptom and the condition when the symptom is detected.
>> GO TO 5
4.
CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR” mode and check real time diagnosis results.
Verify relationship between the symptom and the condition when the symptom is detected.

5.
PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC Confirmation Procedure for the displayed DTC, and then check that DTC is detected again.
At this time, always connect CONSULT-III to the vehicle, and check diagnostic results in real time.
NOTE:
• Freeze frame data is useful if the DTC is not detected.
• Perform Component Function Check if DTC Confirmation Procedure is not included in Service Instruction. This
simplified check procedure is an effective alternative though DTC cannot be detected during this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC Confirma-
tion Procedure.
Is DTC detected?
