I finaly got the truck to start/run/idle...etc...BIG thanks to ROB <IMG SRC="smilies/beer.gif" border="0">

Now when I try to stop the break peddel goes right to the floor then it slowely applies the breaks??? Now, if I pump it 2-3 times it feels like normal, and will hold pressure fine...

I just replaced the headgasket and the only thing I touched break-related was the vac line from the booster to the carb....? I hooked it up exactly where it was at the start... Would I have to prime the booster or something like that? I did bleed the system, thinking that may be part of the problem, but didn't make a difference.

thanks

Please, please, please
I don't want anything to do with this truck anymore....

someone has to have had this problem some time...

I had similar symptoms once. But doing a -very- thorough bleeding of the brakes got the pedal back to normal.
My only problem now is that it pulls to the right when I'm braking. I bled the brakes again to no avail. Balljoints are good. Calipers and pads are new. Hysteer.

I had the same problem before as well. It turned out to be the BPV.... from drooping the rear axle I wore out the seal in the BPV (the brake valve attached to the rear axle) also if the brakes pull. take off the tires, and brake pads, then clean of the pad and rotor surfaces with and abbrasive. then check for debris in the caliper and pistons.

When I was bleeding it, at the back, every time the peddel was pushed it made like a spring-clank. mabie from one of the drums? or the cluster of lines on the rear/pass side.
It just seems weird that it would change so much when I didn't really mess with it. I'll bleed them again.
thanks

mine was doing that for alittle while and it was really pissing me off. i redid my front beaks a bleed the system the wrong way... but even at that the breaks work a lot better. i still need to bleed them again and bleed them the way the manuel says! <IMG SRC="smilies/biggrin.gif" border="0">

Do you have the link from the tower on your front axle still attached to your frame? I have mine disconnected because I had to cut off the top mount and I get nasty dive to the right when I brake hard. It's ok though, I can just brake through exit ramps on the highway now. <IMG SRC="smilies/biggrin.gif" border="0"> So I think your brakes might be ok.

This is the proper way to bleed your brakes from the Factory Service Manual. Did you do it this way?

Drivers Side Rear
Passenger Side Rear
Passenger Side Front
Drivers Side Front
LSPV

If not do it this way!!!
