Burnish Brake Shoes
Sintered metal linings may not provide maximum brake
stopping distance after brake shoes are replaced. It is
necessary to burnish new brake shoe linings.
IMPORTANT:Do not drive machine with the brakes
applied. The brake shoe linings will overheat.
IMPORTANT:Do not allow the brakes to lock up. Al-
low brakes to cool between applications.
1. Drive machine while making 6 to 7 normal stops at
about 200 ft (60 m) intervals while traveling at 10 to 15
mph (16 to 24 KPH).
2. Make several normal stops with the machine going
in the reverse direction. This will self adjust the clear-
ance between the brake shoe and drum.
