6. Visually check the machined rotor's surface finish. Any deterioration in surface finish quality usually indicates worn cutting tips. Always use the
cutting tips recommended by the brake lathe's manufacturer.
7. A secondary finishing operation improves rotor surface finish. Some brake lathe manufacturers offer lathe-mounted tools for this purpose. In no
such tool is available, Saturn recommends using silicon carbide 150 grit emery paper mounted on a sanding block. Using moderate pressure, hold
paper against the rotor as it turns in the lathe for 90 seconds per side.
8. Throughly clean machined rotors with a spray solvent such as Saturn Choke and Brake Cleaner or equivalent.
