nothing with the rotor was powder coated, no powder coat touches the brake rotor but they are ordering a new rotor to make sure its the problem and its fixed
it was a clanking noise when the brake was applied and louder when the brake was pressed harder, the service guy rode it and felt it and heard it the very first time i brought it back but that time they couldnt "reproduce" the sound and as far as pushing the bike i never noticed because i only roll backwards on its own free will if its going forward its because im riding it
We aren't saying that the rotor is powder coated. We're saying that the area of the wheel that is in contact with the rotor when said rotor is mounted to said powder coated wheel, is now thicker because of said powder coat... That may cause the rotor to be offset or appear warped when torqued to the wheel when the problem is the thicker wheel.
Now you say clanking sound. Do you mean like the clunk from first gear to second and vise versa? What I was getting at asking about when you heard the noise, is if something was dragging against the rotor, you would hear a constant brushing noise. And if the rotor was warped, you shouldve heard a rhytmic brushing noise from the pads when they came in contact with the rotor. The reason I asked about pushing the bike around is because if something was dragging against the rotor, it would be tough to push the bike around.
Did they say what caused the rotor to warp? If it is indeed warped, how do they don't know the replacement won't warp as well?
