brake pads
When the brake pads are worn down to less than
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 replacing the brake pads, the inside of the
pulley must be turned so that it is smooth and
even as the pulley also acts as the brake drum.

6. use your calipers to measure the thickness of
both brake pads.
— if both brake pads are more than 1 ⁄
8
" thick,
then the brake pads do not need to be
replaced. re-assemble the lathe parts in
the opposite manner that you disassem-
bled it in
Steps 2–5.
— if either of the brake pads is less than
1 ⁄
8
" thick, damaged, or contaminated with

7. resurface the inside of the pulley. if you do
not have the machinery to do this, we recom-
mend taking the pulley to a brake shop for
resurfacing.
8. replace the brake pads with a new set.
9. install the resurfaced pulley, then re-assem-
ble the rest of the lathe parts in the oppo-
site manner that you disassembled them in
Steps 2–5.

sure it works properly before placing the
