INSPECTION
●Visually check lining for abnormal wear, damage, and peeling.
●Using a scale, check thickness of lining.
CAUTION:
If necessary, remove brake shoe, and check as follows.
●Check shoe sliding surface for abnormal wear and damage.
●Check anchor pin for abnormal wear and corrosion.
●Check return spring for sagging.
●Check adjuster for rough operation.
●Visually check inside of drum for abnormal wear, damage, and
cracks. Using a pair of vernier calipers, check inside of drum.
INSTALLATION
1. Apply brake grease to the contact area of show at left.Standard lining thickness : 3.5 mm (0.138 in)
Lining limit (A) : 1.5 mm (0.059 in)
Standard inner diameter : 172 mm (6.77 in)
Maximum inner diameter : 173 mm (6.81 in)

2. Attach upper-side return springs to brake shoe as shown in the
figure. Be sure to install return spring B over return spring A.
3. Orientation of adjusters is different for LH adjuster and RH
adjuster. Assemble adjusters so that threaded part is expanded
when rotating it to direction shown by arrow. Contract adjuster to
assemble.
CAUTION:
When adjuster was disassembled, apply brake grease to thread.
4. Assemble torque lever in direction of installation as shown in the
figure.

5. After assembly, be sure that each part is installed properly.
6. Fix disc rotor with wheel nut, and adjust brake shoe clearance.
Remove adjusting hole plug. Turn star wheel on adjuster in
direction A (for both wheels) until disc rotor locks. Then turn star
wheel in the opposite direction for 6 notches.
7. Rotate disc rotor to be sure that there is no drag. Then install
adjusting hole plug.
8. Adjust parking brake cable.
CAUTION:
If brake shoes were replaced with new ones. Carry out break-in
operation.

Operation Procedure
1. After obtaining customer's information, perform BRC-32, "Basic Inspection" .
2. After turning ignition switch OFF, connect CONSULT-II connec-
tor to data link connector on vehicle.
3. Start engine and drive at Approx. 30 km/m (19 MPH) for Approx.
1 minute.
4. Stop vehicle. With engine at idle, touch “START”, “ABS” and
“SELF-DIAG RESULTS” on CONSULT-II screen in this order.
CAUTION:
“ABS” may not be displayed on the system selection
screen in the following case: When “START” was touched
just after engine is started or ignition switch is turned to
ON. In this case, repeat procedure from step 2.
5. Self-diagnosis result is displayed. (If necessary, touch “PRINT” to print self-diagnosis result.)
●If “NO MALFUNCTION” is displayed, check ABS warning lamp. Refer to BRC-32, "BASIC INSPEC-
TION 3 ABS/4WD WARNING LAMP INSPECTION" .
6. Check the faulty part indicated by the chart to repair or replace.
7. Start engine and drive at Approx. 30 km/m (19 MPH) for Approx. 1 minute.
CAUTION:
●Check again to make sure that there is NO FAILURE on other parts.
●If wheel speed sensor [SHORT] is detected, ABS warning lamp does not turn off until following
conditions: Vehicle is driven at Approx. 30km/h (19 MPH) for Approx. 1 minute, even in normal
conditions.
8. Turn OFF ignition switch to prepare for erasing memory.
9. Start engine. Touch “START,” “ABS,” “SELF-DIAG RESULTS,” and “ERASE MEMORY” on CONSULT-II
screen in this order to erase fault memory.
CAUTION:
If memory cannot be erased, proceed to 6.
10. Drive at Approx. 30 km/m (19 MPH) for Approx. 1 minute. Be sure ABS warning lamp is OFF.
