I have an 89 GTA, 4 wheel disc. I have to floor the car for it to come to a stop and it wants to roll when I do that still. I think its air in the lines...What else could it be?

 

unless you've had the system open air didn't get in. have you bothered to look for leaks or check the condition of the pads? might be a good place to start.

 

changed all the apds already, changed the fluid last week and bled them. The fluid was brown and had alot of particles in it.

 

i'd be checking the soft lines then

 

Sounds like your master cylinder has gone out. I had the same problem in my Lincoln.

.....by stating "to the floor" you're implying that the brake pedal is touching the floor board and you're practically standing on it??...if that's what you mean, then it definately sounds like your master cylinder is KIA.

 

I am holding the brake to the floor and it slowly rolls to a stop

 

Yep, you need to send out a search party for your master cylinder.

....someone else back me up here.

 

Yea man you need to check your master. Are you losing fluid fast? Quick test might be to park her after a drive and check to see if you're leaking out from the rear. Might I sugest you look into steel lines as well. if your lines are starting to colapse, that will also cause you problems. I'm getting to that point myself....

 

IM not losing fluid. I think the E brake line isnt adjusted right.
