1970 2002...OK. the slave cylinder is done.. time for the master. Do I need to pull the pedal box for this? Ive been reading other posts and it sounds like I might. not sure tho. been through 4 different manuals but they all feature older/newer/different models.. but not mine :( If I pull the hydro lines and get the bolts off... I think I maybe answering my own question... the nuts are in the pedal box. gotta pull the carpet and plate to get to the nuts and clutch pedal connection right? anything else I may or may not need to consider? 

 

Thanks for any help!

i was able to do mine with the pedal box and engine installed.  Just need a second set of hands to start the bolt/ nut from the inside.  Hopefully you have the metal pipe that goes to the reservoir because i feel itll make it easier.  My car was an auto so the only pipe i can find from BMW was a plastic one and its hard to work with because it doesnt want to stay in the master cylinder's rubber grommet.

 

I would suggest sucking out some brake fluid from the reservoir until it is under the nipple for the master cylinder.  saves  clean up and possible paint damage when taking line off the master.

 

best of luck!

If you can't find a FAQ on the board for this task, drop me an e-mail and I'll send you a copy of the column I wrote on the job.  It's pretty straightforward but there are a couple of little tricks that makes it easier....

 

cheers

Mike, would you like to publish it here or does it belong to Roundel?

here is the new master cylinder...the two bolts on the old one were so crusty that I could just take the nuts right off from the inside. (pic 3)

here are the nuts... one above the rubber boot and one hiding underneath. tricky to put em back in. two people would have helped. but I can testify that a one man show can do it. long arms help.

 

 

now that I have the old carpet out I dont want to put it back in... anyone have a carpet kit?? ;)

 

Thanks all!

Bit late to the party, but I just replaced both of my clutch cylinders and I'm having a tough time connecting the line from the reservoir into the Master Cylinder. I tested it on the old cylinder and the line end (which is shaped like a cone/funnel) can be worked in. The rubber is in bad condition so it's easy on that one. I don't want to break or damage anything so some advice would be really helpful. Does the rubber seal come out?

does the grommet need to come out first?  Does it just get pushed in there?

 

This is one of the weirder engineering decisions by BMW, imho.   The grommet is the seal for that pipe. Because it's not a pressure line, the rubber grommet is adequate to  seal the inlet, although the pipe seems loosely connected.   I assume you have a new grommet.  I wouldn't trust a used one.  

 

With the grommet in the MC, the pipe is just pushed in there until it bottoms out. The connection is quite flexible until it is fitted at the reservoir.

 

I attached the (clean) pipe before installing the MC.  I did it on the bench to be certain it was seating properly.   Paranoid.  I hate brake fluid.
