Ok, so I did a search with no luck. 93fzj and my problem is this. When I turn into a parking space or driveway while turning and applying brakes the pedal goes nearly to the floor and a weird sound can be heard coming from somewhere which I can't pinpoint. The sound is hard to describe but not a grinding or scraping sound. The truck is hard to stop but after it does this if you left of the brakes then reapply the brakes act normal. This has scared the shizzle out of me a couple times. It only does this while turning and slowing. It has never done this in a straight line. All the other forums I've seen doesn't describe this problem while turning . Any suggestions? Only does this every once in a while but scary when it does it. Thanks
