brake problems, vehicle doesnt stop

[StangYellow]

Ok, so its not my Mustang, but its a brake problem....
My 97 F150 was sitting for awhile, and when i went to go and drive it again, there were no brake at all. The truck would sometimes NOT stop at all, and would "slam" on and off. The truck would shake, and there were no brakes. So i replaced the pads, and the rotors looked like they had been done before i got the truck. While going for a test drive, the truck stopped better, but not very well. While slamming on the brake, i blew up a drivers side brake line. I replaced that brake line, bled BOTH sides 2 times and still no brakes. I topped off the brake fluid and everything. Im guessing its the master cylinder or the proportioning valve?

This was posted on the f150 boards but they dont have the # of members like stangnet. Looking for some quick help. Thanks

You could try to bleed your brakes ...

yeah, i bled both sides twice. Master cylinders are cheap, but im not looking foward to bleeding those things. Ive done handfulls of brake jobs and never had zero brakes when I was done. This is new to me

What does the F-150 have for a booster? Is it vacuum or hydroboost like the Mustang?

I was thinking booster as well... maybe a leak in your vacuum?
(of course I am used to older cars setups)

most likely it's the master..

I agree its most likely the master. How does the pedal feel? Is it really stiff to push down? There is the possibility the ABS is not working. I had that problem on my Pontiac, and it turns out the abs was blocking fluid to the calipars. I had the system de-activated, and it workes fine now.

There is no pedal at all. My foot goes right to the floor. If i lift up a few inches off the floor, the truck rolls foward. Thats because i only have rear drums stopping the truck right now. I was also told to bleed the ABS line. Im going to figure out where that is and see what happens. The Stang as a daily car is getting old now. I want my truck back!
