clutch pedal falls to the floor

[Bimmer_man]

this thing just started. i drove it to work and left it for about 4 hrs. then got in it nad noticed the pedal was on the floor. i pumped it a few times by hand and nothing. no resistance at all. i checked to see if i was loosing fluid, nope res was full. i checked under my car just to be 100% and it was bone dry on the black top. Then all the sudden boom its like it catches again. idk what to think of this, it has a brand new master and slave for the clutch and i have full power im my breaks so its just the clutch. I dont know a whole lot about the trans and clutch stuff but before i go tearing into my bell housing to figure our wtf is going on has this happened to any one else and if so what was the issue? Do i need a new clutch or throw out bearing er something?

Try bleeding the clutch line from the bottom. I had a clutch that stuck to the floor and followed this diy and it fixed it.

Maybe the slave isn't seated properly. I would definitely try bleeding before re-seating the slave.

My money is on a failed master or slave, even if it's brand new.

I had same problem about 9 months ago. Not losing much fluid and yet I had no pressure. Number 7 on the chart was my problem. It was cracked where it bends. Peel back the carpet to see if there is any fluid seeping on the inside of the firewall.

it was the master cylinder. im getting a replacement one for warranty this time its made in Germany so it shouldn't fail on me like this POS one did.
