I pulled the clutch and brake master cylnders off the Spitfire this weekend after they both started leaking. It looks like the seals had shrunk. I also could not believe the crud outside the cylinders. I'm strongly considering going with silicone brake fluid since this is the second time my paint has gotten messed up. Where do you folks buy your silicone brake fluid. Just pop down to the local FLAPS. Any preference to brands? What's the cost?
