I was having a brake problem on my '90 325i, and thought the master cyl might be the problem. It was not. I put a brand new master cyl on it and I still don't have much rear brake pressure, so now I've narrowed it down to a restriction in the ABS pump or the prop valve. Anyway, there's nothing wrong with it, I just changed it to try to narrow down my problem, and it wasn't it. My interchange at work says it fits 325i '89-'91 and 325ic from '89-'93. WILL NOT FIT 325ix. $25 + shipping.
