PARKING BRAKE SHOE
• Check thickness of lining.
Disc Rotor Inner Diameter Inspection
• Check inner diameter insi de drum area of disc rotor.
Other Inspections
• Check shoe sliding surface on back plate for excessive wear and damage.
• Check anti-rattle pins for excessive wear and corrosion.
• Check return springs for sagging.
• Check adjuster for rough operation.
• When disassembling adjuster, apply PBC (Poly Butyl Cuprysil) grease or equivalent to the threads.
• Check either visually or with a vernier caliper to see if there is any excessive wear, cracks, or damage inside
drum area of disc rotor.
INSTALLATION
Installation is in the reverse order of removal.
• Refer to PB-9, "
Removal and Installation" and apply brake grease to the specified points during assembly.
• Assemble adjuster so that threaded part expands when rotating it in the direction shown by the arrow.
• Shorten adjuster by rotating it.
NOTE:
After replacing brake shoes or disc rotors, or if brakes do not func-
tion well, perform break-in operation as follows.
1. Adjust parking brake pedal stroke. Refer to PB-5, "
On-Vehicle
Service".
CAUTION:
• To prevent lining 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 lining.
2. Perform parking brake burnishing operation by driving the vehicle forward under the following conditions:
3. After burnishing operation, check pedal stroke of parki ng brake. Readjust if it is no longer at the specified
stroke. Refer to PB-5, "
On-Vehicle Service".

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 MONI TOR” 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 MONI TOR” mode and check real time diagnosis results.
Verify relationship between the symptom and the condition when the symptom is detected.
>> GO TO 6
5. PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC Confirmation Procedure for the display ed 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 Manual. This simplified check procedure is an effective alternat ive 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?
YES >> GO TO 8
NO >> Refer to GI-38, "
Intermittent Incident".
6. PERFORM BASIC INSPECTION
Perform a basic inspection of the IPDM E/R.
Inspection End>>GO TO 7
7. DETECT MALFUNCTIONING SYSTEM BY SYMPTOM
Detect malfunctioning system according to PCS-6, "
System Description" based on the confirmed symptom in
step 4, and determine the trouble diagnosis or der based on possible causes and symptom.
>> GO TO 8
8. DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
