i've just replaced the lines, all four rotors, and pads, as well as the emergancy brake shoes, and sensors on my 91 e32 bmw, and now the brakes wont hold pressure in the lines. when you press the pedal, its really stiff and almost wont budge, then just goes to the floor. does anyone out there know what the problem might be?

I would say you have either still got air in a line or you have an airlock, try re-bleeding the system...or a leak which when you press on the pedal releases fluid and lets air back in when you release.

the pedal-end stuff is secured, and it might be possible that i have a leak, or still air in the lines, although the lines were bleed atleast 4 times

Put some paper under the car and with the engine running pump the brakes and check for fluid leaks.

It would also be worth putting some paper under the servo as well.

Is the fluid level dropping then? If not it is probably just an airlock.
