REMOVAL
NOTICE:
Before starting the work, make sure that the ignition switch
is OFF and depress the brake pedal more than 40 times.

No. 1, never deform it.

Until the work is over, do not turn the ignition switch
ON.

Front brake caliper pressureRear brake caliper pressure
2,256 kPa (23 kgf´cm2, 327 psi)2,452 kPa (25 kgf´cm2, 356 psi)
4,413 kPa (45 kgf´cm2, 640 psi)3,334 - 3,727 kPa (34 - 38 kgf´cm2, 484 - 540 psi)
7,845 kPa (80 kgf´cm2, 1,138 psi)5,197 kPa (53 kgf´cm2, 754 psi)

INSPECTION
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: 4.0 mm (0.157 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 and uneven wear, replace the brake shoe.
3. MEASURE BRAKE DISC INSIDE DIAMETER
Using brake drum gauge or equivalent, measure the inside di-
ameter of the disc.
Standard inside diameter: 230 mm (9.06 in.)
Maximum inside diameter: 231 mm (9.09 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 lining 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.
5. MEASURE CLEARANCE BETWEEN PARKING
BRAKE SHOE AND LEVER
Using a feeler gauge, measure the clearance.
Standard clearance: Less than 0.25 mm (0.0098 in.)
