Loss of brake peddle

I aggree with the guys that a leak is likely your problem and you have already had advise on how to check and repair that.
In the event you have no leaks or air in the system THEN
IT MUST be adjustment at the rear shoes. (measure your drums your shoes should be adjusted to give a small amount of drag) also your drums may be oversize. (this sould help remove some exessive peddle travel.
There is ONE More place you can loose your peddle . IF YOUR FRONT CALIPERS ARE STUCK (not sliding freely) Your piston will have to travel too far for one pump on the peddle. You may have noticed week braking and may have noticed a pull to one side or the other for some time. If it pulls to one side when you brake it will be the opposite side thats stuck. ( check your front pads see if one is almost worn away and the other not waring at all. Their are two small tubes mounted in orings that suport by the two caliper mounting bolts .These tubes should slide in the orings allowing the caliper to centre over the rotor each time the brakes are applied. This allows both pads to apply with minable foot travel

If it was shoe adjustment, once pumped up the pedal would not sink to the floor.

That will not cause the issues you are seeing. If you have explained the problem correctly you have a leak.

I agree with T-bucket23 the porportioningn valve has nothing to do with what you have described in your post.all it does is regulate the flow front and rear.it is a pressure thing so you could adjust it so the front brakes will brake slightly before the rear. cole

Start by bleeding the furthest wheel away from the MC. I once had a 80 Chevy truck that I could'nt get the brakes working correctly even by conventional bleeding methods. What I did to get them to work is to gravity bleed them. All you do is open up the bleeders and let gravity do the work. It takes awhile but it will work and is usually less messy that pressure bleeding. Just keep a pan under the bleeder to catch the fluid and keep the MC full. It may take 2 or 3 hours to bleed this way so buy plenty of beer.

Probably time to go see a shop about your brakes. Don't go and mess with that proportioning valve or you will have even worse issues.
