    Bleeding your Slave Cylinder.

    Looking for solid Tips and Tricks on this maintenance procedure for the Home DIY'er.

    I've got a 1987 325e with 2.7i that is giving me a hell of a time. Here's my description cross posted from another thread.


    Anyone got tips on bleeding the slave cylinder?

    When the car is running I can't get it into any gear with the clutch pressed to the floor. The pedal feels squishy and stiff all at the same time. I'm going to take it off the trans and make sure the push rod is seated on the fork correctly but i'm also pretty sure I have some air in the system. I can shift through the gears with the car off, with the clutch or without.

    So far i've tried Pressure bleeding with a Motive Bleeder (Thanks Brian!), Gravity bleed combined with 100+ pumps of the clutch pedal after closing the bleeder, and the Oil Can pumping BF through the bleeder up to the reservoir.

    Happy Fathers Day!

    I appreciate it! I thought getting the thing running was going to be the biggest hurdle but bleeding this Slave has been an experience to say the least. I'm at the point where I want to completely drain all the fluid out of the System and start from scratch.

    Funny thing is when we used the Pressure Bleeder to bleed the Slave I was getting kind of "airy" brake fluid coming out of the slave (looking through a clear tube) and it wasn't coming out at a rapid rate by any means. When I let it gravity drip I always have a steady drip coming out of the bleeder that can be increased the more I open the bleeder.

    If when using the pressure bleeder you pushed at least 100cc of fluid through the system it would be fully bled. In which case the difficulty in shifting when the engine is running (in the absence of leaks at the slave or lines) will be; a) a bad master cylinder, or b) a worn out clutch.
    The car makes it possible, but the driver makes it happen.
