Not at all my sort of thing...been YEARS since i did much to do with hydraulics-I can't stand the liquid-back to the question at hand: What-if anything-do any readers know, uses a master cylinder-or clutch master or slave cyl- with a 27mm bore? This actually isn't f or a brake master, but the hydraulics are the same, it is for one of our Ferraris, its clutch, is in a MAG casting...housing bore is 27mm, inner shaft dia of seal is 17mm, width of the shoulder which rides on the plunger is 8mm...its for a clutch "slave" oddly enough... I found that 997 GT/2-3 cars use a 27mm cylinder, asked for a kit and sizing, , but Porsche told me to pound sand...in no uncertain terms..
I believe Tilton or Wilwood make some masters with bores 1" and larger. CNC (the dune buggy people) may also.
Thanks fellas Goldline typically "last line" of defense .... Thought I'd try if something "local", and or "simple" Always like this trying to get to the track it seems! Thanks again..
Lockheed 1960s wheel cylinder seal-used in some art of Land Rover NLA, naturally...have an appropriate cross reference located.
