Hi Folks:

Owner of a 1994 E420 sedan. Going through a very tough time with my brake replacement. Brought the car in to my independent mechanic who uses oem replacement parts whenever doing any major service.

Replaced all four of my brakes and rotors. Had to bring it back twice due to very loud screeching in front and back which was also triggering my anti-lock brakes on occasion. Third time around he managed to quiet down the squeeching but one rear wheel still makes a loud noise without the brakes on up to about 20MPH and makes some noise again when the brakes are applied. It is better than before but far from right. My old brakes made no noise and my mechanic explained that the newer materials are better for the enviornment but are prone to to this problem which he sees all the time. He also said that he preferred the older versions which may have improved the front two wheels this time.

Is there anything that can be done by a dealer than an independent in terms of fixing the issue? Are we missing anything? Is break in the critical factor?

My mechanic says check after 300 miles.

My mechanic has treated me well and this has been a major expense and I want to get the car back on track.

Thanks for reading.

D.H.
