Default help! big problem

Every now and then my pedal would get soft while driving and i would pretty much shift without a clutch. The way to get it back would be to pump it alot of times. I eliminated the problem of the clutch itself. I changed the master and i just put in a new steel braided line. Once i bled the car, it worked perfect for a nice cruise. I parked it and got back in an hr later and its acting up again. Getting hard to shift. I really dont think its the slave. You guys think its just air getting into the lines somewhere? Because again, once bled it works amazing till parked.

Well...since the slave is the only part that hasn't been changed I would say it is very possibly the problem. The other thought is that you may be boiling the fluid. Have you check the fluid color to see if it is dark at all? Are the lines wrapped in a heat resistant material? Are the lines run behind the heat-sheild?

I completely understand. I would check the the fluid first: Is it clean and clear (and under control...it was too easy)? If it is dark/discolored then you should flush and refill the hydraulics (I suggest using a higher boiling temp fluid and there are tons available). I know you mentioned changing the line, but if the fluid is dark you may still be boiling the fluid. Is the line run behind the heat sheild? Is it heat-wrapped too? Sometimes redundancy is the easiest way to insure you don't boil the fluid on these cars...though i am sure you know this. Let me know what you find and we can continue trouble shooting. Thanks!

How are you bleeding it? I've had absolute hell in getting the line clear bleeding it manually myself, if you don't have a mighty vac pic one up, they're quick and simple to use and you can bleed it from the engine bay. Not just going by a notion here, the problem you're describing are classic symptoms of air still in the line.
