I just replaced my front calipers on my 380 SEC the dealer sold them for about $200 each..if you have a place called Bap Geon...I got mine for $89.00 and got $20 back when I gave them the old ones..my benz has floating front calipers on them and I think they are more $$ not sure. I also got the front brake pads for $34.00 instead of the $70 dealer price. I did buy new rotors for the car for $76 there also.
ONE WARNING they did order the wrong parts for my car the first time but the 2nd time they got it right.
Once your rotors are warped they can not be fixed. I had a terrible bounce on the front right side..this took care of the problem I had.
