Brake rotor finish — How to apply the proper finish

Achieving the Proper Brake Rotor Finish for Optimal Performance Brake rotor finish, or its surface “smoothness,” is rated by its Roughness Average (RA). The RA should be below 80. The proper RA is critical to achieving the proper transfer layer for adherent-style brake organic and ceramic pads as well as abrasive semi-metallic brake pads. If the surface is too smooth, it’s impossible to form a transfer layer onto the rotor face. If it’s too rough, the brakes will make noise, wear faster and even lose stopping power.
