Clutch bleeding- did I just get lucky?
 

I just swapped out the severely leaking clutch master on my 240D with one from a parts car. Of course I removed it, and then came to this forum to do some research on bleeding. Well after reading all the horror stories I was discouraged to say the least:eek: So this morning I put the master in and resigned myself to having to fool with it after work. After it was bolted in I filled the brake cylinder and pushed the clutch pedal to the floor, then waited for the air bubbles to stop coming up. After about 20 pumps on the clutch pedal I had a good firm pedal so I went for a test drive and guess what- it works great!!!:D:D Did I just get temporarily lucky or could it possibly be permanently fixed? Anyone else have the same experience?

I hate you. :P
You must have done something wrong, go back and re do it, that was too easy. :rolleyes:

I think since you didn`t replace the Slave Cylinder, the whole system wasn`t opened up to let air enter from below. then it was just a matter of the air rising from the MC.

I'm sure the clutch gods will smite me sometime soon, but for now I dodged a bullet! I did only go to the end of the driveway (about 3/4 mi) but I ASSume distance isn't relative to hydraulics:D

Its probably because you are one of the good guys in OD.
The Hydraulic Gods have been watching over you & saw the opportunity to reward you for all your good posts in OD. :D

I just finished putting the leaking master back into the parts car with the same result. I think I should buy a lottery ticket!:D I have severely curtailed my OD postings because life is too short to try and change the minds of true believers:rolleyes:

Yes the 240D can get most of the air out of the system by simply letting it sit. I would normally do a quick two man bleed and then let it set over night. It would then be good to go. Don't expect this to work on all hyd clutch systems in other vehicles. Evidently this one just has an upward moving line from the slave, so that the air can work it's way out.

Every day, man is making bigger and better idiot-proof things, and every day, nature is making bigger and better idiots. So far, I think nature is winning.

I suppose I wouldn't have been so fortunate if I had also replaced the slave cylinder. I think pushing the pedal down (it stays down by itself) then pouring fluid into the hose, then attaching it to the reservoir and waiting a few minutes lets it self bleed. I did put a plug on the end of the line to the slave cylinder while I was doing the work. Time will tell if it actually worked:D

So true! You can't fool Mother Nature:D
