brake pads
When the brake pads are worn down to within
1 ⁄
8
" thick they must be replaced. if the brake pads
completely wear out, then metal will grind on
metal and the pulley may be ruined. When replac-
ing the brake pads, the inside of the pulley must
be turned to renew the surface as the pulley also
acts as a brake drum.

6. using your calipers, measure the thickness of
the brake pads.
— if the brakes are more than a 1 ⁄
4
" thick, then
the brake pads do not need to be changed
at this time. re-assemble the lathe in the
opposite manner that you disassembled it
in
steps 2–5.
—if the brakes are 1 ⁄
4
" or thinner, then pro-
ceed to step 7.
7. replace the brake pads.
8. resurface the inside of the pulley by turning
off a small amount with another lathe so the
inside surface is smooth and even. if you do
not have access to another lathe, consider
taking the pulley to a brake shop for resurfac-
ing.
9. install the resurfaced pulley and re-assemble
the lathe in the opposite manner that you dis-
assembled it in
steps 2–5.
10. start the lathe and test the brake to make
sure it works before placing the machine
back into regular operation.

of the brake, feel free to call our technical
