Question about 1996 GMC Suburban
OK so here whats happening. I was coming home from camp and about halfway thru the trip the brake pedal got very soft and i had to push it almost all the way to the floor to get the brakes to start working and the emergency brake indicator light come on and has stayed on ever since. When i got home i shut off the veh and pulled the negative cable to drain the juice out of the veh and reset the ECU. When i attempt to step on the brake when the veh is not running it is very responsive but when the veh is running it is not. I checked the fluid to see if there was a leak and the fluid level is perfect. I can get the brakes to lock up once the veh slows to about 10-20 Kms per hour. I am thinking air in the line? any suggestions would be helpful.

Thanks for the advise - turns out there was a hole in one the lines that was not noticible until it got worse. I replaced the line and all is well. Brake booster is working perfectly.
