Dennis, if you have done a brake job my experience is that is is not uncommon for the brake pedal to sometimes feel a little soft. Why I don't know but I've had it to happend. Usually a trip or two around the block and it they get better.

Now for the air.....If you have bled your brakes and have a firm peddle just let the truck sit for a few minutes. Then push on the peddle. If it goes lower than previouly it has air in them and needs bleeding....Plus, if it has air in the lines the pedal will usually "pump up" higher when you pump it a few times.

Theres all kind of ways to bleed the brakes but when by myself I put some brake fluid in a bottle. I use a an empty water bottle and drill a hole in the plastic top. Pour a some brake fluid in it, stick a piece of vacumn hose down in the bottle making sure its submerged in the fluid and attach the other end to the bleeder valve. Open the bleeder valve and gently pump the pedal. It will get all the air out. It is nice to have someone watch the bottle and let you know when all the bubbles have quit coming. Tighten it up and got to the next wheel. I just did this on a complete brake job I did on a friends 50 Ferd and the pedal is rock solid.
There is also differing opinions on which wheel to bleed first. I have always went to the one furtherest from the master cyl then the next fartherest.
Just be sure you do not let the master cyl run out of fluid as you will have to start all over again. It may be worth it to give it another good bleed job. Takes very little fluid....just e sure to pump enough to get any air out that may have been trapped back up the line somewhere.
Good luck and let us know how you come out.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
