No brake pedal, at wits end...

I went through similar with an e46. Did you check the check valve?

It may seem to be "checking" but it may be leaking. I checked it by blowing against it into a container with water. It seemed fine with lots of resistance to my blowing but the bubbles showed otherwise so I replaced the valve along with the vac pump.

Thanks g300d, being proactive, because I had exhausted so many other options, I initially checked the valve and line as good, but somewhere between the next booster and new MC, I replaced that entire line (with check valve) just on posterity... sadly the only difference it made was my wallet $79 lighter...


My initial fluid pump died on me so my recirc idea hasn't come full circle yet, I'm just back with a new pump and getting ready to setup, my hope... is that just letting it cycle through the system in a constant, unsealed loop, will eventually \ finally, push the remainder of any air out.


If this doesn't get me a pedal back, well, I'm not really sure what's next, I've tried to not think that far ahead (for the moment).
