Brakes, Again....
I have no brakes, at all. The Anti-lock Light is on. The pedal is slightly somewhere near stiff if I basically jam the thing, otherwise it smoothly goes to the floor. It'* not leaking out anywhere. The light being on and the brakes doing the same thing they've done thirty times makes me think that ABS box has died, I have one from my 94, they look exactly the same but the 94 one says "Traction" on it. Will it swap in?
This all looks like an internally leaking master, But I'm on my third one, I'm starting to doubt that diagnosis.
If I bypass the ABS, building a real brake system some engineer hasn't gotten into and "improved" will the ecm go nuts or will it get over it?
I don't need ABS if it'* going to periodically take away all braking, This is seriously pissing me off. I love this car, But I'm seriously considering buying something else because every two months or so I have no brakes.

What'* your bias thingy (forgot the name) doing?

That pressure differential switch? I don't think i have one as a seperate unit, might be part of the PMV....
