964 Brake Booster Pump

[poli84]

My brake booster pump is caput and I am tracing down a replacement. This is for a C4, I think it is also called brake pressure pump.

Does anyone have any second hand replacement leads? I've put a call out to APorschapart.

Thanks in advance.

Ouch, this can get expensive, ask me how I know... What exactly is wrong with it, they can fail in a few ways? Make sure it's not a faulty switch that caused the pump to run constantly and burnout.

I have a working, but faulty pump if that is of any use? It didn't burn out but rather developed a leak from some pitting at one end where the line enters (apparently lack of use, my car only saw 40k in it's first 24 years.) So replaced with a new pump, switch and line.
