This one had me stumped for a while. The above solution should work. The reason a brake hose can cause this is that if they over-crimp the piece of metal in the middle of the brake hose that holds it in place and/or the rubber in the hose swells too much as it ages, the passage through the hose can close off where it goes through that metal piece. Once this happens, the brake brake fluid can still force its way through the hose when you step on the brake, but the caliper will be unable to fully release. This will overheating everything and cause the brake pads to wear very quickly.

Have the brake pads been so very work they are down to the metal? This could cause the caliper piston to extend too far and not be able to retract properly.
Calipers Fail mostly from a cut in the rubber boot around the pistion dirt and debris get in there and rust the piston and it cannot retract properly Do they retract after they cool Down? if so the brake fluid has "boiled" if brake fluid is not changed about every 24,000 miles condensation builds up and lowers the boiling point of the brake fluid causing this problem.
Tell me does it happen after a long drive or siting a long time in heavy bumper to bumper traffic in hot summer weather? I recommend a complete brake fluid flush an change the calipers with NEW ones ot rebuilt and use dielectric grease on all points of metal to metal contact between the caliper an the mount bracket and thee ends of thee pada n the slide points they ride on and the pins that go through thecaliper and thread into the mount only dielectric not regular grease it will cause sticking and a worse problem than you have now.

It's normal for new pads and rotors to have a "wear-in" period but only for say 50-100 miles of average driving... Disc brake DO get pretty hot, especially after prolonged or hard braking... (going down long hills or a lot of hard stops)... also front brakes actually supply 60% of stopping force... If they aren't to hot to touch the wheel or smoking you are probably OK... One thing to make sure of is that the pedal has "free play"... usually a fraction of an inch before the brake push rod actually pushes the master cylinder piston. Without this free play the brakes WILL drag all the time and wear prematurely... but unless you replaced the master cylinder or the locknut on the push rod adjuster has come loose it's rare to have that problem... The only other cause of this would be a malfunctioning ABS unit and you would feel a definite pulsation... Hope this helps...;-)

You need to jack up that wheel and spin it by hand, if you hear the similar noise it is most likely a noisy wheel bearing. Also if you have revently driven over loose metal road could be stone lodged in disc assembly. Could also be the wear indicators on the disc pads "telling you" that the pads are nearly worn out.
Hope this helps cbacer

do you do a lot of hills work?if so use the gears ,ifdown hill not the brakes if it is auto then slip it down i gear . make sure your rear brakes are adjusted regularly,but for the main part i would think it is the driver that is the problem,you may get an occasional faulty rotor but not three sets, over heating is the cause of your problem.dont missunderstand me chrysler brakes arent anything special but they arenot that bad , slow down
