Hey gang.
Last summer I had a problem with my master cylinder in my syncro, or so I
thought. The pedal would "Sometimes" go all the way to the floor but could
pump up to build pressure. Other times it would work fine.
Anyway, I replaced the master cylinder, bled the system and all was well.

Well now about 1000 miles later, i've got the same symptoms occurring. The
fluid level has not gone down, so I don't have a leak. It feels as though
something has blown out and is allowing a piston somewhere in the system to
move freely. I'm thinking it's the master again, but it sure is weird to
kill two as quickly as I have.

Any thoughts?
When the pedal works, it's firm and functional. But sometimes I get a firm
pedal, and while keeping my foot on the pedal it slowly moves towards the
floor.
