I'm looking at the brakes of my 580E and the discs look like the ones in this illustration. I think mine is the serial number before sn 16270319. but the part number for the disc is the same up until the wet type discs. Can anyone tell me just how worn the disks can be before they're too thin. I measured mine at 3/8". They look like they should work but I'm not sure if the operating mechanism will run out of travel and then not apply the brake very well. I just can't find this info in the service manual or anywhere I've looked. I did find that new ones are .439 inch thick.
