WTB Brake Bomb and Regulator

I have a 635, but I think they are the same part as a 5 series.

Looks like E28 5-series and E23/E32 7-series.

Seems like a pretty common part. Wouldn't have thought it was so hard to find it.

They are a commonly failed part. I believe they are specific to 535/635 cars. You might try posting on MyE28.com and see if a member there has one for you. A new one would probably be best, considering how often they fail.

New would double the cost of the car. I found one I think on craigslist.
