[Mini] 50mm diameter 25mm hole 6,3mm thick..........

[Dr John C Bullas]

Yes, I got some mini disk brake wheel bearing pre tensioner plates
made up today out of 50mm mild steel rod

Could take orders on some more if you wanted one?

See diagram in supplemental section of the Haynes Book of Lies - it is
used to ensure the bearings
on later disk braked minis are correctly compressed when the drive
flanges are refitted

Mini failed MOT on brakes and the disks look shot after sitting around
for 10 years :)

might get them skimmed as they are cross drilled vented ones
