Hi, I have a 2013 C300 and seem to be having the same problem...over return. The one question I have is with regards to correcting. It seems New SHocker Guy just moved them about 1 or 2 mm with his wife pressing the pedal. In an earlier post Glyn suggested putting old pads in without friction material and stepping on the brakes which I believe would cause the piston to move pretty much to its length and then slowly bringing it back in until you can just put the new pads in which would pretty much bring it to the fully retracted position. Is there a preferred way? How do you know how far to retract the piston...trial and error until you can fit the pads?

Thanks for any advice
