You know when you ride the brakes to a slow stop and you get that loud a** screachy metal grindin noise.. well i have that but not as loud and not when i apply the brakes lol. it happens when im slowin down(w NO brake pressure) or just startin to take off. i cant tell if it happens at higher speeds bc of the wind and stuff. but what could this be. i doubt a wheel bearing.
** it gets faster as i pick up speed, or slower when i lose it**

Could still be the brakes. The pads are still applied to the rotor even when not applying pressure.
Change your pads or suffer the consequences!

Your brakes, when wearing, will first start squeeking, then as it gets worse, it stops squeeking and starts making a hissing/grinding sound. It will eventually sound awful, like you're dragging a cement cinder block down the street, grinding it away.
The brakes applie pressure as they wear down even when you're not pushing them, and if you wait too long, you can grind your rotar to a thin peice of scrap metal (happened to me once w/ my old Saab). It was paper-thin by the time I brough them in....$700 later, it was a lesson well learned wink1.gif

I have seen brakes ground down till the PISTONS were grinding on the vanes that are ordinarily on the inside of the rotor. Scary to think it was a heavy duty pickup carrying lumber for a building contractor too.

Had a simular problem with the grinding noise. Turned out the parking brake would not fully release. Pulled the caliper off and oiled the return spring and brake cable to fix that one.
A pulsating pedal normally indicates a warpped rotor from either overheating or being hot and hitting water.
