Lately, the brake pedal travels to the floor when turning sharp driver, such as doing a U-turn or turning into a parking spot. Brakes go out and and I have to pump them to get the pressure back. Happens when I turn slow and happens when I turn fast. I have noticed that it gets worse if I raise the rpms up while turning (clutch).

Only happens when I turn driver. The truck is lifted, but the lines have plenty of slack at full turn, brake reservior is full, tried bleeding the brakes (no change), no loose calipers, tried it with and without the RABS engaged (no change).

You might try pinching off the flexible brake lines. Try pinching off the left and right independently of each other. That way you might be able to tell which side of the braking system is causing the problem. Be careful when pinching the flexible line not to damage it. Jim

 

Sounds like your wheel bearings are loose
