Stainless steel "S" caliper piston for calipers that take 7.5" wide brake disc as used on all Cooper "S"variants and early 1275GT.
These are correctly ground for long life and fitting against the seals, but more importantly have the raised crown section on the area to allow the fluid to correctly push the piston out.
Beware of the many copies out there that are not correct.
