INSPECTION
1. INSPECT BRAKE DRUM INSIDE DIAMETER
(a) Using a brake drum gauge or equivalent, measure
the inside diameter of the drum.
Standard inside diameter:
254.0 mm (10.00 in.)
Maximum inside diameter:
256.0 mm (10.08 in.)
2. INSPECT REAR DRUM BRAKE SHOE LINING
THICKNESS
(a) Using a ruler, measure the thickness of the shoe
lining.
Standard thickness:
5.0 mm (0.197 in.)
Minimum thickness:
1.0 mm (0.039 in.)
HINT:
If the lining thickness is at the minimum thickness or
less, or if there is severe, uneven wear, replace the
brake shoe.
3. INSPECT BRAKE DRUM AND REAR DRUM BRAKE
SHOE LINING FOR PROPER CONTACT
(a) Apply chalk to the inside surface of the drum, then
grind drum on the brake shoe lining to fit.
HINT:
If the contact between the drum and the shoe lining
is improper, repair it using a brake shoe grinder or
replace the brake shoe assembly.
4. INSPECT BRAKE WHEEL CYLINDER
(a) Check the cylinder bore and piston for rust or
scoring.
