There was a recall on the brake master cylinder in order to fix a problem that causes the brakes to drag when the brake pedal is not pressed. If the brakes drag, they will fade, causing overheating and increased stopping distance. The master cylinder is replaced under the recall.Google+

We are now at approx 100000 and have first, turned then replaced the rotors.
Next, we replaced the rotors. Wiggling steering wheel after approx 50 miles @ 50 mph is the condition since brand new.
Time to turn the second set of rotors.
Chrysler never informed us of any master cylinder recall.
We purchased the car from the showroom floor in March 2000.

I have the same problem of brake drag feeling on drivers side but had no idea of recall. To date I've replaced wheel rotor & brake pads (thought maybe warped), wheel bearing hub(Thought maybe bad), Rims(ditto),Drive axle complete(ditto),even thought maybe engine alignment, it doesn't affect overall performance but boy is it annoying as hell!

front driver side brake locking up. Just happened today.
My 2000 300M Brakes lock up and the pedal becomes stiff. I replaced the 4 rotors, calipers, pads and the master cylinder, and I still hear the brake dragging. I had a hard time removing the master cylinder. I was able to remove the master cylinder by using a screw driver and hard knocking it with a heavy hammer. it took me about 6 hours of hard work to remove the master cylinder. The problem being that salt got into the compartment that attaches to the master cylinder cavity in the mount and solidified like a hard rock literally fusing the master cylinder to the mount. You must use water the loosen the grip of the salt and a screw driver between the cylinder and the mount to pry the master cylinder loose. You also must completely replace all of the break fluid and use plenty of lubricating grease so that the break pads slide easily when the breaks are applied. If you are replacing rotors make sure the wheel assembly rolls freely and without noise before mounting the rotors. If you feel friction of any kind, remove the rotors and clean the wheel assembly with brake cleaner. Lubricate all moving parts of the assembly.

The front breaks lock up and the break pedal becomes very hard. I replaced the 4 wheel rotors, calipers, and pads. I can't remove the master cylinder from the master cylinder mounting.
