no brake pressure

[manfig24]

Hissing noise coming from abs module while car is off and no pressure in pedal

I've replaced booster and m/c and old rusty brake lines

[evildky]

you have air int he lines, bleed, bleed, bleed

[manfig24]

Is that noise from the abs module normal though?

[evildky]

I havent had a Z32 in a few years I really don't recall. There are bleeder valves adjacent to the abs motor.

You definitely need to bleed the ABS if there has been an air leak for any extended period of time, or when changing fluid.
The hissing noise is odd though as I've never experienced that with either my NA or TT, perhaps that's your air leak?

[manfig24]

I ordered an abs pump cuz I figured it was leaking air

Let us know how it goes!
