The clutch master cylinder on my 323i is leaking badly, so I need to get a replacement. Does anyone know however, if you can get a refurb kit for these, or what other BMW or indeed other cars use this particular master cylinder?

Real OEM tells you what other models used a specific part.

Just checked and all models of e21 used the same part but it wasn't used on any other series of cars.

If you can't find a rebuild kit, buy a cheap alternative cylinder and just fit the internals.

That's the conclusion I've come to. The other alternative is to use an E30 one and make a new pipe (the one that connects to the slave cylinder on the 'box), but that's a last resort.

W&N has a refurb kit and the cylinder. BMW has also the kit and the cylinder.

And I have the kit and the cylinder.

lucas girling service kit for e21 ate clutch mastercylinder ...sp 3648..(no kit listed for fag mastercylinder) you might be able to order this by kit number at a car shop or garage ...i don't think a e21 will be listed in any current girling parts book because of the age ....edd ...p.s I can email you a scan of the full e21 page out of girling parts book if needed ( photobucket seem to lower the res on upload and the part numbers can't be seen after)

That would be great if you can, thanks.

e21 meister if you want a photo scan of the e21 girling brake parts page then send me a p.m with the email address you would like it sent to....edd...

Does anyone know if the internals of an E30 clutch master cylinder are the same as an E21 equivalent? I know the inlet for the clutch fluid pipe is in a different place, but otherwise it looks the same externally.
Would the dimensions of the internal parts differ between say, a Girling or an ATE?

I bought one off RetroB which I'm sure was an E30 cyl (can you confirm if reading this?) but it works fine.
