Someone  has asked me if I can rebuild the front wheel cylinders from 
a '65  squareback, but I've never seen any of those. Can anyone tell 
me what the  seal inside them looks like?

It would either be a solid disk, like the  rears, with no center hole, 
or it would be a "ring" that fits in a groove  around the piston.

Which is it? The parts book indicates that 61-65 are  all 22 mm 
(actually 7/8" = 22.2 mm) so they are the same diameter as the  late 
rears, but I only have replacement seals of the solid  type.



I'll try. There's a spring, that's attached to a "cup expander", followed  
by a cup, then a piston, then the boot. I don't know if that helps or not. I 
got  the info out of the Blue Bentley, as my wheel cylinders are in various 
states of  disassembly at this time (part of the reason I when discs on the 
64). From what  I saw though, the "cup" didn't have a hole in it.
