Left Disc DRAGS...??????

Defintiely pump the pedal and crack the bleeder as described above,this will rule out any line problems,new lines can be defective,Ive seen many that were bad at the shop i was working at.Rotor thickness wont be a problem either as stated,I have seen cars pull occasionally if the the thickness form side to side was more than .025 due to differences in friction/heat (some cars are picky) but not drag,that would be a mechanical problem.

.025"??? Is that a typo?
That is 1/4 of 1/10 of an inch!
That's less than 2/3's of a millimeter!
I find it hard to believe that any cars brakes would be effected buy a difference this small, considering that I have changed one set of front pads one day after work and the other side the next day after work. The brakes worked fine and there was at least .400" difference between the two, that's over 10 mm's.
