Brush Research Flex-Hone For Rotors, Fine Grit (Pack of 1)

Changing brake pads? Rotors looking a little shiny? Here's the answer! Yes it's a bit time consuming but the results are well worth the effort. The front brakes of my R1100S were pulsing a bit and I initially suspected warped rotors. Hmm. Well, my first thought was just buy some new ones.. How much?!?! That got me doing some research and discovering according to many rider/mechanics motorcycle rotors rarely if ever warp. One particularly vocal proponent of that view (who also was an R1100S owner) suggested this tool would not only cure the pulsing but would also create a fine cross-hatch pattern typical of new rotors and perfect for bedding-in new pads. $400 for two new rotors or $35 for the tool? No brainer! Even if the pulsing wasn't cured.. Well, the short story is the pulsing was cured! And the rotors look like new! Here's the fine print - it does take a fair amount of time. The outside rotor faces are easy, just raise the front wheel so it can rotate easily, give it a spin and then keep it spinning by applying just the right amount of pressure with the spinning hone. (turns out the correct amount of pressure for optimal honing is the same amount of pressure required to keep the wheel spinning) The inside faces require removal of the wheel, flipping the rotors over (or installing them on the opposite sides) and then re-installation of the wheel to perform the honing. If your bike has directional rotors (like mine does) when you're done honing you have to repeat the wheel removal, disk switch/flip and re-installation so the rotors are correctly oriented. All told it was probably a 2 hour process for me. $180 an hour? I'll take that any day!

Works great

I used this Hone for the brakes on my 2004 Honda Goldwing. The rotors were true and just needed de-glazing. This hone worked very well. I left the rear rotor on the motorcycle and let the engine turn the rotor while honing it. When I completed the job, no squeeking and the brakeserform like new.

Helped my 1997 F350 quite a bit. The calipers and pads are a rusty disgusting mess, new pads to come, but in the mean time I chucked this tool in the drill and did both front rotors on the truck. The truck has never had the rotors turned or been fooled with at all in nearly 20yrs. This went real smoothly, and in a few minutes per rotor I was deglazed and the brakes are far improved. Once I replace the worn out rusted pads with new, I suspect brakes will be even better. Good tool. I had no problems at all.

Wasn’t bad wasn’t good. I had multiple of the stones fly off but it still did a decent job, and was able to get the glazing off my rotors with it

This abrasive brush tool does an excellent job putting an OEM finish on brake rotors. I leave the rotor chucked on the arbor in the lathe still running after final turning using the carbide lathe bits and then use the brush in a variable speed, reversible drill for about 15 to 20 seconds on each side. Don’t press hard and don’t go fast. If your drill is reversible, you can run it in the opposite direction and brush the rotor again to give it a truly non-directional finish. After using it on several jobs, I can absolutely say that it was definitely worth the money to me.

Had a different brand for years before it wore out. This one fell apart after only using a couple of times.

This did a nice job of resurfacing my motorcycle rotors. I was able to do 4 rotors and likely can do more yet. I did chuck the rotors in a mill and spin the mill while I used a cordless drill to run the hone on the rotors surface. The process took some time but the results were worth it. My only complaint is that these are fairly expensive. I would expect them to be about 1/2 the price they are. Then again it is much cheaper than a set of rotors.
