1995 Dodge Neon Brake Sticking

Ok, well I went down there and undid the bleeder screw that connects the rubber hose, but I cant seem to figure out how to undo the other side of the rubber hose. It looks like it is made into the metal piece that holds it to the car. On a brighter note ( or not so bright ) after undoing the screw the brake releases fine. After everything is tightened back up the brake still holds for about 25 seconds now with out releaseing. I am a amteur mechanic, with little knowledge about these things and could use all the guidence available here. Thanks. And for what was responded, releasing the caliper bleeder, that would release the brake regaurdless, like, isnt that what is supoe to happen when you undo the bleeder bolt, you lose brake presure, so I dont know if this even proved anything, fluid is running through the hose fine, my stepdad seems to think it is just a bad caliper, like we got a bad one from the parts store or what not, please, give all the insight you can as he states he has never seen a collapsed hose, and highly doubts its that

Nevermind on the not getting the piece off, the screw was stripped holding it to the firewall, but I forced it out, but now its kinda late so I have to wait till tomorrow to goto autozone to pick up the replacement cable ill let u all know how it works out

Well, there was no clip, its all one piece monted with a screw. I got it all undone just have to wait untill the parts store opens back up tomorrow morning. I will post more details about it then to let u all kno if it works or not

After bleeding them so much hoping to solve the problem. There is little to no fluid left in the holder. Will this cause problems or?

Ok, after installing the new line, I cant get any brake pressure AT ALL.I bleed them, fluid comes straight thru like it should, tighten it back down start the car no pressure, builds pressure when the car if off, but the minute the car starts the pedal hits the floor, instalation is identical to the passenger side I cant figure out what else went wrong

I bled all four disc brakes on the cra, fluid came out with no problem I went around the car twice just to make sure they bleed fine and I have went through a half thing of double sized brake fluid. So I am not sure

On top of all that how could I possibly know when all the air is out of the lines, and it would it just be the line I was working on or all lines, or just bleed on line till im through a whole bottle of brake fluid, and judge it like that and say well, if a whole bottle of brake fluid isnt enough to get all the old fluid out ( fluid with air between it ) than there must not be any air in it. And then move on to the next one and do the same. And just to make sure that we are doing it right, car is OFF. Pump the brake untill you can hardly push it down, hold it there, undo bleeder bolt, let the pedal hit the floor, hold it to the floor untill the the bolt is tightened back up all the way and than repeat. And some where along the way I should run into some spittin fluid as that would mean air in that line. And also, keep an eye on the brak fluid in the resovoir as if it runs out the same issue happens again. Let me know if I am on the right track here, or if there is a better way to stimate if there is air in the line. Thanks so much guys

So only do it twice? If thats the case than I am pretty sure air is not the problem, as I went around the car twice. First time front left, twice, than rear left, 3 times, 3 times on rear right, and 3 times on front right. Each time same result from all brakes. But just to be positive I onced over each caliper again. Anything else that it might be other than air in the lines? Or should I try bleeding again?
