Jeffrey,
You brake problem sounds, to me, like a perfect example of a bad seal in
the brake master cylinder. Instead of acting like a piston, your master
cylinder is acting like a dashpot (i.e., shock absorber), where although firm
under a rapid impulse, the fluid can slowly leak past the piston under
steady pressure.
You can buy a kit to renew all of the rubber seals in a master cylinder
for very little money. I am not a pro at this, but I am aware that
sometimes people also hone the cylinder, but I wouldn't know when this is
necessary.
