Pulsating brake and rear rotor stuck to axle

[IndianaJoe]

I have an 03 excursion w/ 100k miles on it. I recently had front rotors turned and new pads b/c of a faint pulsating in the pedal. (what the heck after 100k:-)). I could not easily get the rear rotors off and figured most of the problem was in the front so I did a pad slap on the back. Not so many miles later my SO tells me she feels the pulsating again when braking. Tires were recently replaced. Does this sound like bad rotor (as in not turned properly) or simply turned properly but heated up and warped again? Other issue? I have also heard that over tightening lug nuts (re recent tire change) could stress hub and cause problems. As for getting the rear rotor off if I get into the brakes again do you have any suggestions? I did not spend a lot of time on this but suffice it to say I gave it a few good hits with a bfh and it didn't budge. I refrained from using a puller but is that an option? This rotor has the hub built onto it for the ebrake so it could be a real pia.

Could simply be that the parking brake shoes are holding the rotor on. Did you try backing the parking brake shoes off first?

I didn't try adjuting the parking brake yet, does that require a special tool? I had an issue on another vehicle (Taurus) and went about it like Tim Taylor splittng the drum w/ a grinder. I know, drastic but it worked. I would rather do things differently here. I will likely get into this over the weekend. Funny thing is it would not budge, making me think it was siezed to the axle. Both rear rotors acted the same:-(
