Greetings fanatics. I'm new here and this is my first post. Hoping to find my way, seems to be the right place to ask the questions I have. Bought a used 2005 F-350 last August. Very nice, clean and well kept. Had 110,000 miles on it. Almost immediately the left front caliper seized so I replaced them both along with the pads. The truck brakes fine but the brake pedal stays down. I have to raise it with the tow of my boot, better than half the total travel distance of the pedal itself. Also, there seems to be some hiss-n-whine when I turn. It lessens when rpm's rise but doesn't completely subside. The power steering fluid and brake fluid are at normal levels. Would someone please advise me what this is about and maybe a smart progression of where to start to fix this? Would be very much appreciated. Hope to figure out where to start.

Thanks,

Steve

sounds like you have some hydro-boost problems.
