REAR BRAKE(Parking Brake for Rear Disc Brake)

2. MEASURE BRAKE SHOE LINING THICKNESS

Using a scale, measure the thickness of the shoe

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 excessively uneven wear, replace

the brake shoe.

3. MEASURE DISC INSIDE DIAMETER

Using a vernier caliper, measure the inside diameter of

Standard inside diameter:

170 mm (6.69 in.)

Maximum inside diameter:

171 mm (6.73 in.)

Replace the disc if the inside diameter is at the maxi–

mum value or more. Replace the disc or grind it with a

lathe if the disc is badly scored or 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 improp–

er, 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 0.35 mm (0.0138 in.)

If the clearance is not within the specification, replace

the shim with one of the correct size.

Shim Thickness

0.3 mm (0.012 in.)

0.6 mm (0.024 in.)

Shim Thickness
