Also, if the seals in the MC are failing and letting fluid bypass, the pedal can go to the floor. I started by looking for fluid at the wheels, even though the MC reservoir was full. With no fluid loss, I couldn't think of how air got in the lines. So i figured I'd start by replacing the MC. I watched a few videos where the pedal problem was fixed by bleeding the 4WAL.

I bought the Motive kit. I've watched about fifty YouTube videos on GMT400 brakes and read the long threads on here. It looked like the Motive pressure bleeder works best and easiest.

I've found a mobile brake service who has an OBD 1 scanner that can activate the ABS module. I might get him to come do it.
looks a nice kit, but you have to pump it like a plebeian! I let my air compressor do the work and it cost less than half. ;)
