e30 brake pressure regulator

[aceifty]

Does anyone know where the e30 brake pressure regulatorg is on a 325i cab

Is there one? I don't think there's anything in the plumbing between the master cylinder and the calipers, other than a simple brass T-piece by the fuel tank.

if there isn't one then what is the thing that is just above the chassis leg on the passenger side, just below the master cylinder. only asking as i have fluid leak from there (what ever that thing is)

the car does have rear factory brake discs, but non abs

Hmmm, according to RealOEM there is such a thing, but I don't remember seeing one on my touring. Seems like you've answered your own question.

As for the leak, are you sure it is that thing, not the master cylinder leaking down the brake pipe?

Pressure regulator is on the bulkhead in the engine bay, just a few inches from the brake master cylinder.

iv checked all the pipes and the mastet cylinder and they are dry, the only thing that is wet is the thing below the master cylinder

Can i just replace the seal on it or will i need to replace the whole thing

[Brianmoooore]

BMW don't list any individual parts for it, But I expect it's just a copper or alloy washer that you should be able to get from a motor factors. May just need tightening up.

Ill try tightening it up and see if that stops it, if not then ill remove the whole thing and take it from there
