Front Rotor Grinding Help Please???
During a routine inspection my local mechanic said my rotors were too thin and needed to be replaced. No big deal, I can do that at home. I got some pads, new rotors, some lithium grease tada, time to go to work.
Took the pads off, removed the wheel bearing assembly, the rotor, put all new shiny parts on, repacked the bearings and put it all back together. Unfortunatly, I either did something wrong, or the parts are wrong. After bleeding the system and making sure everything was tight, my father and I took the stang for a testdrive. Not 100 yards up the street the front wheels locked up and we had to force it back home with the whole thing shuddering and jerking.
Off come the wheels and this is what we find:
The rotors are being eaten up by the calipers. The /NON/ contact surface of the rotor is grinding against the caliper assembly. there are four nice little shiny grooves in the caliper now between the pads. With the calipers bolted in tight the rotors are nearly impossible to turn, and we spent three hours trying to figure out what could be wrong.
The wheel bearing assembly is fine, without the caliper on the rotor spins free and there is no grinding. Once the caliper goes on though, the rotor doesn't turn, and there is a lot of noise as it grinds against the caliper. The rotors are the same size as the ones that came off, both width, diameter, and height, the pads match up with the ones that came off, and I have no idea where to go from here.
If anyone has any ideas as to what could be wrong I would be more than happy to hear it.

Yes, I can see the part that is rubbing. Too dark to take pictures right now, but here is a little paintshop thing to look at.
The black areas are where the rubbing is at. The rotor is rough and worn along the edges, and there are very nice grooves in caliper.
I'll upload some pics of the actual caliper and rotor later today.

certainly sounds like you have the wrong rotors...
Im assuming you didn't bother matching them up with the old ones before installing them.
bad move
We really need pictures of the actual parts. As many as possible!

Thanks for all your help guys. Took me long enough to find the problem. My error. I forgot to grab the inside wheel bearings off the old rotors. Pony all pretty and running now :P Blond moments are priceless.
