ROTOR HONE USAGE INSTRUCTIONS
For changing material compound of brake pads (organic to sintered or vise-versa), the rotors should be thoroughly cleaned on the pad track area by either bead blasting or employing the easy to use new Rotor Hone.
The easiest way to use the Rotor Hone is to do it on the bike;
With the front end off the ground on a proper stand, get a buddy to spin the wheel. Using a hand held drill set in the low RPM/high torque mode, angle the abrasive balls of the hone at about 10 degrees off of parallel from the rotor surface applying medium pressure to pad track area. You’re looking to remove the darkened burnished deposition layer to the clean and bright base rotor material. Using this process, an ideal circular cross-hatch surface is created. It’s simple and relatively quick. Do both sides this way. Remove the wheel and reverse the rotors by flipping them over (when offset permits), repeating the process to condition the opposite sides.
When down to a clean surface, it’s time to clean the remaining abrasive particles left by the Rotor Hone as the final op. You’ll need a stiff bristle toothbrush and Acetone (Denatured Alcohol alternatively). Dipping the brush into a small container of Acetone, aggressively brush the rotors pad track area with generous amounts of Acetone (of course use proper eye protection and approved rubber gloves). Again, this a quick and easy way of eliminating contaminants leaving a clean surface ideal for fast and hassle free bed-in of new pads. Stainless steel rotors can be cleaned as detailed above or with soap and water…be sure to rinse thoroughly.
WARNING: The Rotor Hone employs Aluminum Oxide abrasives, which if applied to excess, can cause rotor damage. Do not excessively hone one spot but rather follow the instructions detailed in Step One. Take your time to get the hang of proper usage. Done correctly, the results are most satisfying.
NOTE: Not for use on CMC rotors.
