Feeling ripped off on the cost of a front break job ?

If the rotors were not warped to begin with, then it sounds to me like they messed up the install of the right caliper, causing the rotor to warp. One other thing is that those original equipment rotors are big heavy mothers. Most brake places cannot resurface them correctly because they either don't have the equipment or the time. Just had mine 2006 e450 done. Mechanic sent the rotors to a machine shop. Cost with new pads, bearings repacked, oil change and everything underneath greased, NYS inspection $600.
