Flex-Hone® for Rotors utilizes the patented Flex-Hone® technology to produce the ideal surface finish on automotive and motorcycle disc brake rotors, automotive fly wheels and clutch plates. More rotors per hone than abrasive pads.
This piece of junk didn't last for one rotor.I like to freshen up my rotor when I change brake pads.The abrasive balls disappeared before my eyes as I deglossed one rotor.I will go back to the random orbit sander.
After a while your brakes start to lose performance and unless you have a bead blaster or want to use sandpaper to clean the old glazing and chemicals off you need this. Instead of getting new rotors and wanting to get that braking performance back use this and get the circular contact area back and clean up the rotors.
