Well I got my G20 from my cousin when he messed up one of the calipers on the front. The piston wouldn't compress back in. I went and bought 2 remanufactured calipers from the parts store, and put them on. I bled the brakes as the FSM says, drivers rear, pass front, pass rear, drivers front, and before that I also bled the master cylinder. I watched the fluid level the whole time as well.

Here is the problem. When the car is driving there is no pressure on the brake pedal at all, it will go straight to the floor. If I pump the brakes fast, it will build pressure and grab the rotors hard, and also will drop the RPMs down. As soon as I give the car any gas, the pressure will go away and the pedal will go straight back to the floor. I found a hose that was all cracked and split so I replaced it. How do I get the car to stop right. The G20 is a 1991, and has ABS. Is there a certain thing I have to do to bleed ABS eqipped cars?

SOMEONE PLEASE HELP ME!
Thanks
James
