Spongy Brake Pedal
I am about bleed the brakes on my 1997 F-150, but I was wondering, is a spongy feeling just the way these truck's brake pedals feel? because when we got the truck back in 97', the brake felt a bit spongy too, always has. or maybe have I had a bad master cylinder the whole life of the truck?

I have a 98 and the brakes were never awe inspiring by any stretch. If you have never replaced the brake fluid do it now. It might save you in the long run. Adjust the rears up while you are back there. I would expect improvement but no miracles.
A bit of advice from my main brake guy. Put a brick under the brake pedal to limit the piston travel in the master cylinder. It is possible to ruin the piston seals by pushing them into territory they haven't seen in years. The unused portion of the master cylinder bore is a good place for corrosion and crud to build up.

Once you have bled the brakes, you shouldn't be going into "unknown" territory for the master or slave cylinder pistons. It is only for bleeding to keep from pressing the pedal down too far.

You are absolutely correct. I should have made that very plain.
Soak the bleeder screws with pbblaster several times before you start the bleeding procedure. Let us know how it turns out afterwards.

Thanks - Expect post tomorrow night Wednesday 4-20 for my results.
