Q: trouble bleeding back brakes on 1991 GMC Vandura 2500

Edit
The rear brake line blew out half way back. I drove the van for 2 or 3 short trips with just front brakes. I replaced the brake line and am trying to bleed the back brakes, but when I have someone hold down the brake pedal while I open the bleeder valve, nothing happens. Is there some component that needs reset to allow fluid into the back system again? Also, the brake light on the dash is on.

air bound. the light is on showing hydaulic difference. when you get a peadl, it will go out. you may have lost the master cylinder since the pedal went to the floor. it may have ripped the seals in the master.
