Brakes

I have a 2001 7.3. When I apply the brakes very quickly they work until i slow down to about 10 MPH then the pedal goes down to the floor or if i reapply the brakes. If I apply the brakes slowly at any speed the pedal goes down to the floor. Any solutions or recommendations?

Have you looked around for a fluid leak?

I would check all your caliper slide pins are greased and moving, pads and calipers. If you find any leaks repair them. Do a good bleed on your brakes and see how it does after that.

Yep master cylinder time. Make sure to bench bleed your master cylinder or you will have a hell of a time getting a good pedal
