Inspect brake drums.
IMPORTANT:Brake drum machining is not re-
commended. Replace rear brake drums as a set
to maintain equal braking forces.
8.
Check brake operation. To adjust the brakes, stop
several times while vehicle is moving in reverse.
A. Clean drums with denatured alcohol. Check
braking surface diameter in at least three places. If
the diameter exceeds 8.071” (205.0 mm), replace
both brake drums.
9.
Adjust parking brake (see Operator’s Manual).
Burnish Brake Shoes
Brake linings may not provide maximum brake stopping
distance after brake shoes are replaced. It is necessary
to burnish new brake shoe linings.
B. Replace drums that are cracked, deeply grooved,
tapered, significantly out–of–round, scored, heat
spotted, or excessively rusted.
IMPORTANT:Do not drive machine with the brakes
applied. The brake shoe linings will overheat.
C. Minor scoring in brake drum can be removed with
sandpaper.
IMPORTANT:Do not allow the brakes to lock up. Al-
low brakes to cool between applications.
