Well, I dig some tests. Since the LSPV bled fine, I started to disconnect the lines from rear going forward. Sure enough, of the two lines going INTO the lspv - one of them did not squirt. I traced it up to the front tire, and still no juice. Followed it into the master cylinder - and took the brake line out - and just a slow drip like all the rest of the points.
So - it MUST be the master cylinder. A buddy in town had one for me, so I picked it up.
What an easy job! Took me like half an hour to swap it out. Piece of cake all around. Reconnected everything and ready to test it - oops - my buddy took off with my brake fuild.
So now I get to wait a day until he comes back so we can bleed the whole system and see if it's fixed.
(I wouldn't be surprised. I heard of another case where a guy replaced everything and it worked for him again. Perhaps there's something that happens if winter hits and freezing temps can affect any air/dirt in the line that results in screwing up the MC?)
