Rear Brake (For Drum Type) Inspection

Check the cylinder bore and piston for rust and scoring. If necessary, replace the brake cylinder assembly or piston.

Using a brake drum gauge or an equivalent tool, measure the inside diameter of the drum.

Standard inside diameter:

228.6 mm (9.00 in.)

Maximum inside diameter:

229.6 mm (9.04 in.)

Using a ruler, measure the thickness of the shoe lining.

Standard thickness:

5.0 mm (0.197 in.)

Minimum thickness:

1.0 mm (0.0394 in.)

NOTICE:

Always replace both the right and left drum brake shoes together.

Apply chalk to the inside surface of the drum, then grind down the brake shoe lining to fit the drum.
If the contact between the drum and the brake shoe lining is improper, repair it using a brake shoe grinder or replace the brake shoe.
