Inspection
1. Inspect brake shoes.
IMPORTANT:Replace front brake shoes as a set
(allfour shoesonboth wheels)to maintainequal
braking forces.
A. Replace brake shoes if damaged or if lining is
worn to 1/16” (1.6 mm). Replace shoes if lining is
contaminated by oil, grease or other fluids.
NOTE: Overheated springs lose their tension and
can cause brake linings to wear out prematurely.
B. Inspect brake shoe webbing, upper and lower
springs and shoe hold down springs for overheating
and stretching. Overheating is indicated by a slight
bluecolor.Inspectbrake shoewebbingfordeforma-
tion. Replace parts as necessary.
C. Inspect hold down pins on adjuster levers for
bends, rust or corrosion. Replace as necessary.
2. Inspect backing plate surfaces which contact with
the brake shoes for grooves that may restrict shoe
movement.Replacebackingplateifgroovescan notbe
