umm yeah i have a 90ls with a 94 ls engine in it. lately my brake pedal has been sinkin to the floor. i checked the brake fluid and i had none in there. and also there was a little green wire going into the master cylinder that was unplugged. i plugged it back in and filled it up again. the brake pedal was tight for a few miles then went all the way to the floor again. any suggestions? i would think replacing the master cylinder but that could be costly. so i was gonna see what you all would have to say first. thanks a lot.

sounds like you have air in the line, be sure to bleed the line thoroughly(you will know when a solid stream comes out) and be sure to NOT let it get below the fill marker
