I would check your front flexible lines as well as your fluid level in the
master cylinder.

Like another poster said, one of the flex lines are bulging up when the
wheel is turned. Change them BOTH, as the other side is probably going
bad too. Sometimes when you change the flex lines, the car/truck has
better brakes than it had when it was new. Don't go cheap on the lines
either. The better ones make for a better pedal feel.

I was working on a car with a really mushy pedal once, and after
changing the pads and bleeding them, something was wrong, the pedal was
almost as mushy as it was before I did anything. I had someone get in
and push the brake pedal. The flex hose on the left side swelled up to a
huge size. I jumped back, as I expected to get sprayed with brake fluid!

Two new hoses and another bleed, and it had a nice pedal.'

Jim, You have a loose wheel bearing. Turning pushes in the caliper piston.
First apply it goes to floor, then the slack is gone and its fine. Replace
the bad hub bearing and itll be fine.
