Just cleaned out my 748s front calipers, was hoping it would be done at the 6000/12month service but is not on the schedule just the fluid changed, they were covered in baked on dust and the gold rough finish seems hold it on!!
But on the hole the pistons and everything were very clean and not much corrsion even after riding through the salt in winter far better that the nissins on my honda. Only the pad retaining pins were really dry so greased them up with some graphite grease along with the pad backs and pistons, no one seems to have any 'brake grease' in any shops.
See how much better they feel when i go out next it is freezing out now
