1.INSPECT BRAKE DRUM INSIDE DIAMETER
Using a vernier caliper, measure the inside diameter of the brake drum.
254.0 mm (10.00 in.)
256.0 mm (10.079 in.)
If the inside diameter is more than the maximum, replace the brake drum.
2.INSPECT REAR BRAKE SHOE LINING THICKNESS
Using a ruler, measure the thickness of the rear brake shoe lining.
5.0 mm (0.197 in.)
1.0 mm (0.0394 in.)
Always replace both the right and left brake shoes together.
If the lining thickness is less than the minimum, or if there is severe or uneven wear, replace the brake shoe.
3.INSPECT BRAKE DRUM AND DRUM BRAKE SHOE LINING FOR PROPER CONTACT
Apply chalk to the inside surface of the brake drum, then slide the brake shoe against the brake drum to check the fit of the rear brake shoe lining to the brake drum.
If the contact between the brake drum and the rear brake shoe lining is improper, repair it using a brake shoe grinder or replace the brake shoe.
4.INSPECT BRAKE CYLINDER AND PISTON
Check the rear wheel brake cylinder bore and wheel cylinder piston for rust and scoring.
If necessary, replace the rear wheel brake cylinder assembly or wheel cylinder piston.
