I have a 91 ranger, 2wd 2.3L motor.
I had a brake line blow out the other day, i replaced it and bled all brakes, i still have no brakes, so i got a new master cylinder, bled that, then bled brakes all over again. i still have no brakes, if anyone can tell me why id really appreciate it. also, when i push my brake pedal my engine revs if you know why that is im curious. thank you in advance
 
The problems is that you have air in the system which is a pain sometimes to get it out
Or the distribution block valve might be stuck or jammed to one side
..
 
Most likely the reason your engine rev's is a vacuum leak disconnect your vacuum assist plug the line and see if it still does it.If it dosn't do it anymore your power brake unit is bad.Got two sitting in my yard but kinda by myself in north east Cali.When you say you don't have brake does it still go to the floor?The best system for me to bleed brakes is to stick a vacuum hose on the bleeder valve nipple put it down to a clear jar with water in it.Have someone work the peddle up and down till bubbles quite coming out and you can see clean brake fluid in the water or do it yourself and keep checking on progress.Shut the bleeder only when your done with that wheel.If you let it run out of fluid you've lost all your progress so keep fluid in the reservoir.Start with the broken line then go to the longest line right rear and work to the left front.With your broken line this is going to take some patience to get fluid moving again especially if you let it run out.If your brake pedal stays high and your brakes don't stop well look into that vacuum unit.

I like your idea for brake bleeding, but its better to put clean brake fluid in the jar. That way when you suck stuff back up into the brake system its new clean fluid, not water that will contaminate your water soluble brake fluid.

Also, when bleeding after a MC replacement, there is a specific order to how you are supposed to bleed the wheels. If you don't you don't ever get all the air out.

Go from the Right rear wheel, to the Left Rear wheel to the Right front, then to the Left front. Basically you are starting at the wheel that is farthest from the MC and moving closer to it.

Also, did you bench bleed the new master?
 
yes it still hits the floor, i unhooked the lines and plugged where the connect to the master cylinder and i had pedal then so ive ruled out the booster or mastercylinder, but i cant find any leaking spots and ive bled the brakes multiple times, ive ran the master cylinder down and filled it up b4 it gets empty and havent found any more air
 
hmm. this is a good one. Check your drums. I had one once, 83 t-bird, came in for a blown line. Replaced that line, he declined the others, and so I just replaced that one and bled it, pedal was still to soft. Checked the rear brakes, they were turned down too low, adjusted them up, hit the pedal, right to the floor. Blew another line!

Anyway, try turning up your drums a bit, just don't over do it or you lock up the rear wheels.

Pull the drums off and make sure your wheel cylinders aren't leaking first though.
 
ya my dad thinks i might have gottten air in the wheel cylinders, and my bleeder screws are really bad so we were using the lines to bleed them so we are gonna replace the wheel cylinders so we can bleed properly
 
Sounds like the best plan.
