I recently installed Wilwood FSL front calipers on my '98 CSVT. I followed all the instructions for bleeding the lines, but I got a soft pedal. I bled the lines two more times (along with the clutch) and I still get a soft pedal. The odd thing is that it is not consistent. Sometimes if I get on the brakes I get a decent pedal - other times it will go almost to the floor. It seems that as the brakes get used more and more over the course of a day the worse they get. The next day I can start off with a decent pedal and within a few braking cycles it gets progressively worse. I'm not sure what else to do now - I'm thinking that maybe my master cylinder is going bad. Anyone run into this problem before?
