Brake Pads

When the brake pads are worn down to less than

18" 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 18" 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 18" thick, damaged, or contaminated with oil, the proceed to Step 7 to replace both pads.

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.

10.Start the lathe and test the brake to make sure it works properly before placing the machine back into regular operation.
