    i have a 1982 k5 diesel and i was on the trails and my brakes were working fine then they just went out and i cant build up pressure at all not even enough to bleed the lines. the power steering also went out because the power steering and brakes run off the hydro boost, so it might just be the hydro boost, or possibly the master cylinder. there are no leaks and the pedal just goes to the floor with no pressure at all to stop the truck

    i need help fast its stuck on top of the mountain and we already wrecked into a tree trying to get it back down the trails, and i cant leave it up there or it will get stripped

    any input or ideas would be greatly appreciated

    Wouldn't do it unless you have no choice but try driving with the parking brake? Scary but just might work

    i would try to walk it down with a couple rigs + straps behind it if you know anybody who has a capable enough truck. tighten the parking break a good amount, use that and compression breaking if possible

    If your pedal dropped to the floor, your master is shot.

    Not trying to be a wise arse, but did you check the belt? Make sure it is on and plenty tight.

    You should be able to crawl it down in 1st gear low range and ebrake to stop.

    even if the belt were bad, the pedal wouldn't go to the floor, the brakes would just be crazy hard to use. i suspect pump or master cylinder - tho i think if the pump were bad it wouldn't cause the problem of the pedal to the floor.
