318is with s50/zf 320 clutch slave problem

[Mesarina]

So my car has been running fine after the swap, I used the stock 95 m3 clutch slave (bigger bore) that came with the trans, It worked great, but 1st gear was hard to get into, the slave didn't have the plastic part at the end, but it got worse, so I bought another 95 m3 febi clutch slave, bleed it and it worked better, problem is, it I press the pedal, in any gear, for about 20secs the car will start to move slowly, like pressure being lost slowly, the clutch system doesn't have leaks, should I change the master cylinder for a new one? use e36 325i smaller bore clutch slave? bad bleading? bad new clutch slave? also what uuc clutch line do I need? sscl-e30, sscl-1, or sscl-2? I like the stiffnes with the m3 95 slave btw

Thanks

Sounds like a leak in the master cylinder to me.

Ok, will try a new one, I hope that's the problem, anyone now what line from uuc should I buy "while there.."

Buy a stainless line from blunt if you want, one piece ordeal.
