1. REMOVE REAR WHEEL
2. REMOVE REAR DISC BRAKE ASSEMBLY
(a) Remove the 2 installation bolts and rear brake caliper. Torque: 47 N m (475 kgf cm, 34 tt-lbf)
Do not disconnect the flexible hose from the brake caliper.
(b) Suspend the disc brake securely. Ensure that the hose is not stretched.
3. REMOVE DISC
Release the parking brake lever, and remove the disc. HINT:
If the disc cannot be removed easily, turn the shoe adjuster until the wheel turns freely.
4. REMOVE SHOE RETURN SPRINGS AND TENSION SPRING
Using needle-nose pliers, remove the 2 shoe return springs and tension spring.
5. REMOVE SHOE STRUT
6. REMOVE FRONT SHOE AND ADJUSTER
(a) Using SST, remove the shoe hold-down spring and pin from the front shoe.
(b) Remove the front shoe and adjuster.
7. REMOVE REAR SHOE
(a) Using SST, remove the shoe hold-down spring and pin from the rear shoe.
(b) Disconnect the rear shoe from the parking brake shoe lever, and remove rear shoe.
8. REMOVE PARKING BRAKE SHOE LEVER
Using needle-nose pliers, disconnect the parking brake cable from the parking brake shoe lever.
1. INSPECT DISASSEMBLED PARTS
inspect the disassembled parts for wear, rust or damage.
2. MEASURE BRAKE SHOE LINING THICKNESS
Using a ruler, measure the thickness of the shoe lining. Standard thickness: 2.0 mm (0.079 in.) Minimum thickness: 1.0 mm (0.039 in.)
If the lining thickness is at the minimum thickness or less, or if there is severe, uneven wear, replace the brake shoe.
3. MEASURE DISC INSIDE DIAMETER
Using a brake drum gauge or equivalent, measure the inside diameter of the disc.
Standard inside diameter: 173.0 mm (6.811 in.) Maximum inside diameter: 174.0 mm (6.850 in.)
Replace the disc if the inside diameter is at the maximum value or more. Replace the disc or grind it with a lathe if the disc is scored or is worn unevenly.
4. INSPECT PARKING BRAKE LINING AND DISC FOR PROPER CONTACT
Apply chalk to the inside surface of the disc, then grind down the brake shoe fining to fit. If the contact between the disc and the brake shoe lining is improper, repair it using a brake shoe grinder or replace the brake shoe assembly.
Reassembly is in the reverse order of disassembly (See page BR—43).
Apply high temperature grease to the parts indicated by the arrows (See page BR-42).
1. ADJUST PARKING BRAKE SHOE CLEARANCE
(a) Temporarily install the hub nuts.
(b) Remove the hole plug.
(c) Turn the adjuster and expand the shoes until the disc locks.
(d) Return the adjuster 8 notches.
(e) Install the hole pfug.
2. SETTLING PARKING BRAKE SHOES AND DISC
(a) Drive the vehicle at about 50 km/h (31 mph) on a safe, level and dry road.
(b) With the parking brake release button pushed in, pull on the lever with 98 N (10 kgf, 19.8 !bf) of force.
(c) Drive the vehicle for about 400 meters (0.25 mile) in this condition.
(d) Repeat this procedure 2 or 3 times.

When inspecting the fluid pressure, inspect the left font and right rear together, and the right front and left rear together.
If the rear fluid pressure is incorrect, replace the P valve assembly.
