I got around to pulling my master cylinder and have a pic of whats there. Its not much. I was hoping there might be a generic o ring with a bit of damage but everyting seems in order. The black seals are 'bell or umbrella" style seals. I have only had one other mst cylinder apart and it had similar type plungers. All I could think to do was run a little silicone under the seals to provide a little more pressure to the cylinder body. I hope there is no conflict with silicone and brake fluid. As I wrote previously this thing squirted a little like it was trying hard to develop pressure so i'm hopeful its just a minor problem.....waynec
