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

He replaced the hoses with the calipers........I'm gonna check the bearing myself........could be too tight I suppose, but it feels like the brakes........I'll crack the bleeder while I'm there and give her a whirl too.

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.
