Just got an MOT warning about front discs and pads. Been getting warnings about this for 3 years now but while it has passed MOT and brakes work perfectly, it appears to be getting near replacement time.. EEK! A little surprised that the discs only lasted 60k miles but this seems to be normal and I guess this is the penalty for having a greater pad area. Incidentally, no warning lights yet? I only do about 4k miles a year. Anyway, I have surfed the usual posts but cannot find definite part #s for the 6 potters. Seems that the 55 is offered anything between 330 and 360mm disks with a combination of drilled, grooved or both. Brembo and Tarox seem to be predominant and I believe that Brembo where the OEM suppliers? Mine are drilled and grooved and I would like to stick with the original type. Eurocarparts list Brembos for about £750 each, a German supplier lists the same for nearly half altho Eurocarparts always seem to offer some kind of discount. Tarox are cheaper. Whatever, the first thing I need is the original part number. MB Club EPC has now gone! Any help out there please? PS. I know about floating calipers but are there floating discs too. The picture of the 360mm clearly shows a seperate hub mounting whereas others are all one piece. Does this indicate a floating disc maybe?
