E36 M3 Evo (Master Cylinder problem) Help Needed

[Bennym]

Hello

I need some help, I own a 1998 BMW E36 M3 Evo, the problem is my Master Cylinder the cylinder at the clutch pedal keeps busting, this is the third times it’s happened, the first two times I used second hand master cylinders, so when they busted I said it could just have been a bad are done master cylinder, so the last time I changed it I bought a brand new one, that was around 6months ago, but the cars starting to act up again the clutch pedal goes straight to the floor and doesn’t return back up to it’s original position, you have to pull it up with your hand, but then the car mite drive for 100miles and no problem, but I have found when the car is cold she is slightly harder to get into gear as if the clutch wasn’t 100% in line are engaged, I had a original clutch installed 10 months ago so it cant be it, I was wondering could it be my Slave cylinder causing the bother???

And if so how could I test it to make sure???


Thanks for any help
