01 View BMW DiagramSee this part on the official exploded view→Brake master cylinder — a genuine BMW part, number 34 33 6 785 666. The number stamped on the part is 34336785666; BMW's catalog files it under the short number 6785666. You will find it on our Brakes shelf, under Other Brakes parts. It supersedes the older number 6779680, so a part carrying that number is the same part.
It fits every E46 body style (320i, 325i and 330i, 2001–2006), with the M54 or M56 engines — and the European-market versions.
BMW draws it on 4 diagrams, among them Brake master cylinder DSC (34_1092) and Brake master cylinder DSC (34_1171). It weighs about 530 g (1.2 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
