BRM Announces Rotor Hones for DIY Brake Jobs; Flex-Hone® for Rotors Imparts Non-Directional Surface Finish to New and Re-Turned Rotors, Reducing Brake Noise and Vibration

Share Article

Brush Research Manufacturing (BRM), maker of engine hones and automotive brushes, announces brake hones for resurfacing new and re-turned rotors. Professional automotive technicians and DIY mechanics alike use Flex-Hone® for Rotors tools to impart a non-directional surface finish that reduces brake noises such as squeaking and squealing.

DIY Brake Jobs with the Flex-Hone® for Rotors

The Flex-Hone® for Rotors imparts a series of scratches or cross-hatch pattern that minimizes brake noise and promotes brake pad seating.

Brush Research Manufacturing (BRM), maker of cylinder hones and automotive brushes, is announcing rotor hones that use Flex-Hone® technology to impart a non-directional finish. Built with flexible nylon filaments and abrasive globules, the Flex-Hone® for Rotors imparts a series of scratches or cross-hatch pattern that minimizes brake noise and promotes brake pad seating.

The BRM brake hone is ideal for new and re-turned rotors, and finishes more rotors per hone. Named an Undercar Digest Magazine Top Ten Tool for 8 years in a row, this reliable, cost-effective rotor brush is a favorite at tire and muffler shops, as well as in home garages where do-it-yourself (DIY) mechanics use the Flex-Hone® for Rotors during brake jobs.

Rotor Turning Examples

By the time a vehicle needs new brakes, the rotors often have grooves or areas of wear caused by the rubbing of the old pads. Unless these surface finish problems are addressed, the new brake pads won’t contact the rotor at the desired angle. By turning rotors in a lathe, mechanics can impart a smooth, uniform surface finish that reduces harmonic vibrations.        

DIY mechanics like Blue95 of, an on-line automotive forum, know that a non-directional surface finish is important, and that the Flex-Hone® for Rotors is the right tool for the job. After building his own brake lathe, Blue95 described how he used the Flex-Hone® for Rotors in a handheld electric drill to “clean up” a Honda rotor and “get the surface refinished”.

How to Resurface Brake Rotors

As the Flex-Hone® for Rotors brochure explains, BRM rotor hones should be held securely in a chuck, collet, or similar holding device. Mount the rotor in a lathe and rotate between 125 and 210 RPM. Then chuck the Flex-Hone® for Rotors in a variable-speed electric drill motor or low-speed air drill, rotate the tool between 300 and 600 RPM, and bring the brake hone into contact with the rotor at a slight angle.

When using the BRM rotor hone, work in towards the center and out to the edge of the rotor face, applying light but uniform pressure. Dwell time against the part is what produces the desired surface finish. Use the Flex-Hone® for Rotors dry and work the rotor brush for just 15 to 20 seconds at a time, typically 10 – 15 seconds clockwise and 5 – 10 seconds counterclockwise.
