I replaced the slave cylinder on my dads 1989 535i, we first tried the regular bleeding like you would with brakes. When this didn't work I looked online in the Bentley manual it said to use a pressure bleeder. I got one, and got it all hooked up pressurized the system and tried to bleed. Fluid came through and it looked like all the air. I closed the bleeder and checked the pedal and it was mush, wouldn't even work.
I tired this multiple times, even clearing out a bunch of white gunk (moisture in the line?), but the pedal felt the same or worse. So i did some more researching and found the "reverse bleeding" method where you force fluid through the bleeder and push the air up and out of the line. Tried this multiple times with the pedal marginally improving.
Am I doing something wrong? i don't understand why it wont bleed and work, if anyone has any ideas please let me know, this is the only thing stopping the car from getting back on the road.
Thanks
