Hard Brake Pedal?
Got in my truck (77 F100) to go and get some firewood last week and did'nt have any brake pressure.....well a bare minimum and I had to lean on it! After a damn near heart attack, and 15 minutes of nursing this thing down the road, they finally came around. It's darn near a daily driver and I've never had a problem before it turned into Siberia around here. I have no leaks what so ever and it's full of fluid. Was it common to have problems with the booster? I've heard there is a check valve for vaccum on it that can stick occasionally. Any suggestions?

Frozen water in the lines maybe? Would probably be a good idea to bleed the brakes and get some new fluid flowing if that hasn't been done in a while.
Not really understanding if you had to push really hard for the brakes to work or if the pedal was falling to the floor.

I had a 76 F100 I drove for 24 years with no power brakes or steering as well, but I never had to get on a brake pedal like I did this thing! It was like pushing a brick wall with your foot. Going fast ain't no problem, but I like to slow down when I need to? It's a bad feeling when you can't......trust me. Already beat cancer once, I don't need to see a cardiologist this soon. Thanks for the help

I had the same problem in my 77' when it was cold the booster wouldnt work...run the truck for a while and the heat off of the engine would warm things up and it would work... I scrounged up some parts from a lincoln and put hydroboost brakes on and the difference is UNBELIEVABLE! I love my hydroboost brakes... for example... now keep in mind they werent working like they should b4 the conversion but after i put the HB on I had a 3,000lb trailer w a 9,000lb skid steer on it and i stopped (not using trailer brakes) better with all that weight then i did with just the truck b4. Totally night and day difference... But besides me getting excited about the hydroboost, I believe your problem lays in your booster and its probably just as easy to replace it...

Not yet. I've resorted to driving my 4runner until tomorrow, and can get to a relatives shop (he's got a lift) and see. I'm almost convinced it may be water in the lines. I actually got in it this morning and drove it, and it worked just fine. I'm still not going to take any chances and assume anything until I see for myself. I'll let you know. Thanks

It's been a tad warmer in NC the last day or so than when the problem showed up hasnt it? I know it has in North Ga. Still cold, but a little warmer. You may be right, couldve been frozen water in the lines if its better now
