Clutch Slave Cylinder

[Bom356]

I just installed a new clutch slave cylinder into my 85' BMW 535i and now the clutch still wont work. It really hasnt been that long since I installed it but the clutch snaps down when I step on it and then I have to pull it back up with my hand.



Was there something I overlooked?

did you bleed the system after you installed it?

This is common on E30s When I change a clutch slave I always recommend the master is replaced at the same time, you can guarantee that a week after you fit the slave the extra pressure will blow the master. There’s a proper way to bleed a BMW clutch if you don’t know it contact me through this site.

When you say master cylinder are you talking about the one mounted in the engine compartment or the one behind the clutch pedal itself?

The one attached to the pedal is the master, the one on the transmission is the slave. It is highly recommended that they are replaced as a set because they both wear out at about the same time.

oh i thought the brake master cylinder and slave cylinder were supposed to be replaced at the same time

It's a general rule that you do. If one fails, it's not too unreasonable to believe the other isn't far behind.

you guys are all getting brake master cylinder and clutch master cylinder mixed up. the brake master cylinder has nothing to do with clutch operation other then feeding fluid to it through the brake master cylinder resivoir.
