Check for leaks by the calipers... I had a front caliper blow out on my 84
about a year ago.
My van was doing the same thing as yours, until I realized total failure
with a puddle of brake fluid under my left front wheel.

Subject: Brake question......

Is this what I've heard described as "brake fade?" I'll be going down a hill
and the pedal feels normal, if there is such a thing, and once in a while it
feels like the pedal all of a sudden will go right down to the floor board.
If I give it a quick pump everything feels good again. That feeling of no
back pressure is a bit unverving when going down hill and I'm sure that's
not the way it should be. Do I need to bleed the brake line?
Any insight will be gratefully appreciated,
Thanx,
pAUL
