have you checked to make sure you have vaccum to the brake booster? I've had the vaccum pump go bad on a '95 I had and had similar brake issues.

It's probably your vacuum pump. Commonly on floored pedal means master cylinder, a hard pedal is usually the brake booster. But on a ford the vacuum pump could also cause the hard pedal as well

Make sure the brake pressure switch isn't leaking. It's on the front of the master cylinder if you have cruise. Pull the wire plug and look for fluid.

If you have a hard pedal it could be that one or more of your calipers are locked up. Did you check them? I know that they tend to freeze up on the slide pins. I actually had the same prob. on my '99 and just replaced all of the slide pins, and problem solved. Plus it's a cheaper "guess" than replacing boosters and the like.

I inspected the calipers and checked the pistons. The pistons check out okay. I will reinspect the cailpers and pay more attention to the slide pins. What should I look for at the slide pins?

THANKS
