2001 Cyclone, PM wheels, stock rotor:

Yesterday I had the local parts place mount new tires. While I was at it, I changed the brake pads even though they had a lot of life left.

Now, the front brake drags horribly through the same 1/4 rotation of the wheel. I've sanded down the pads a bit, re-cleaned and re-mounted everything, and even tried going back to the old pads. Same thing - a not-so-nice "scritch" sound in a consistent area.

Could the shop have bent the rotor? That's the only idea I have left. They did have two chances to screw it up, as the first time they mounted it backwards. I've tried the zip-tie on the fork leg trick but I can't see any problem - but these old eyes can't measure fractions of a millimeter very well!

Thanks in advance for your ideas and help...

Looked at the bearings? Either they are bad or yes I would think the rotor is bent.

Thanks - the bearings check out fine. Most probably a bent rotor, which according to the shop "is impossible to do". Uh, yeah. I don't mind installing a new rotor, other than the horror stories about trying to get the bolts out.

Not bad if you use an impact tool. Buy a good socket from craftsman or the like. (so you can get a new one free when you break it) I use the Kobalt brand from Lowes. Fit socket into bolt head and whack it good with a hammer. Hand impacts are really the best though. IMO Best of luck....

"Buy a good socket from craftsman or the like. (so you can get a new one free when you break it)"

Heh, heh... I brought a Craftsman socket back to the exchange counter that obviously was melted by a cutting torch. The guy looked at it and said, "Could you at least tell me what size it is?".

"Could you at least tell me what size it is?"

ROTFLMAO - even returned items must be properly inventoried!

In the shop's defense, they listened and are investigating "what they can do" for me. I just wanted to let them know, but the manager seems to be stepping up.

I had a Harley shop bend my front rotor on an M2 when mounting a tire. They also had ample opportunity, they mounted two tires in a row with long razor slashes in them.

They said the slashes were from the factory... right before they said "we could not have bent the rotor". It was impossible to miss, every stop and the pistons would be pushed back so far you would need three pumps of the lever to get pressure again.

They never completely confessed, but gave me a new rotor at cost and mounted it for free (back before rotors cost a gazzilion dollars).

If your rotor is the old style with the flat head screws you can use a torx bit to get the screws out.
Pick a size that seems a little too large and pound it in with a hammer. Mine came right out after that.

That happens when the rotor is not clear of the face on the bead breaker. Them Harley guys are used to them little 11.5" H-D rotors.
