I just replaced my pads and rear rotors w/ all new OEM parts. I have made sure that the e-brake shoes are adjusted (I did not replace these). I washed the rotors well too. The pads are in correctly and I can easly turn the rotors by hand. After driving for just a short distance the rear rotors seem to be very hot, I mean real hot compared to the front. Is this normal for awhile after new pads and rotors?
