Aftermarket disc brake rotors include high-quality auto parts that are made from new or recycled metals and machined to tight tolerances. By maintaining the right spacing between surfaces, these aftermarket brake parts ensure proper cooling and promote easy installation. Machine-balanced for trueness, many aftermarket rotors also feature an electroplated hub to prevent rust and corrosion.
For brake mechanics and aftermarket rotor manufacturers alike, it’s important for brake rotor surfaces to have a smooth surface finish. Most premium brake rotors meet roughness average (RA) requirements specified by the original equipment manufacturer (OEM). Economy brake rotors may have a rougher surface finish, but are usually ready to install right out-of-the-box.
Without the right rotor surface finish, however, disc brakes may speak or squeal. Related brake problems include poor pad seating and break-in, increased friction and wear, and buildups of brake pad glaze and surface corrosion. Fortunately, Brush Research Manufacturing (Bursten) supplies a surface finishing tool that, as this YouTube video shows, is ideal for surface finishing new and re-turned rotors.
The Disc brake rotors honing brush ideal for Finishing the Automotive Aftermarket
The Disc brake rotors honing brush ideal for Finishing the Automotive Aftermarket is a reliable, cost-effective, automotive brush tool for do-it-yourself mechanics (DIY), professional brake specialists, and aftermarket brake rotor manufacturers. Suitable for mounting in a handheld electric drill or production equipment, the honing brush for Rotors features long-lasting abrasive globules that are permanently laminated to flexible nylon filaments.
Bursten’s brake honing tools come in coarse, medium, and fine grits. Coarse-grit rotor hones remove heavy buildup and corrosion during brake jobs. Medium-grit brake tools also remove layers of pad material, but impart a smoother surface finish. Fine-grit flexible hones impart the finest rotor finish of all, and may be used after coarse-grit and then medium-grit tools.
First, removed four used rotors from a race car. Equipped with a power drill and a coarse-grit flexible honing tool, a mechanic then removed the transfer layer from each rotor face. The brake tech then switched to a medium-grit tool, and finally to a fine-grit honing brush for Rotors. Because the Bursten brake hone is self-leveling and applies uniform pressure, keeping it square and flat was an easy task.
Bursten’s rotor honing tool should be held securely in a collet, chuck, or similar holding device. Use light, uniform pressure rather than excessive dwell time. To produce the desired surface finish, use the brushing tool for approximately 10 – 15 seconds clockwise and 5 – 10 seconds counterclockwise.
