Brake master cylinder

[Dan323i]

My car has just failed on a leaking master cylinder. Any idea where I can get one? Is it shared with any other BMWs such as an E30? Thanks in advance!

Yeah it will be, i've got one at the unit not doing anything but it's Nas's so you'll need to ask him for it.

Heck, I've just given the garage the OK to order a genuine one from Germany! Ah well.

[Jacko]

New is always best anyway.

[Dan323i]

You'd think so – the garage got one sent over from Germany and it's no good! Been sat on the shelf for years presumably and the seals are all hardened and no longer seal properly. They've taken it apart, soaked all the bits in fluid overnight and reassembled it and it still is not working properly. Maybe I should drop your mate Nas a line...

You could get new seals from biggred.co.uk

uused a master cylinder seal kit from biggred this week briliant service but the kit had the wrong reservoir
rubbers i ended up using the ones from a 98 e39

Yes I had same problem, rung them and they matched them up and exchanged them...

How did you know the use the e39 ones and where did you get them?

[jimbob]

got them from my e39 just lucky they fit
it was thanks to your post i found biggred too otherwise i would have had to get a new master

No Problem. Glad it helped (almost).

I would have hoped they'd of sorted the kits by now, but at least they sorted it out when I contacted them..
