Grinding
The grinding noise is from the the pads being gone and rotors being grinded away. Unless it was just some rust on the rotors from sitting for days.
A pulsation when braking, and a loud screeching noise(pads also gone).
Yes.
Check your brakes(pads and rotors)
Pads are worn down Rotors are rusty and scoured Dirt and grit have been trapped between pads and rotors
bad rotors
Have the front rotors turned on a lathe at a dealership. check brakes and rotors
Typically its wheel barrings but can also be bad rotors.
Normally a rusty rotor would not make a grinding noise. A grinding noise from the brakes usually indicated that the pads or shoes are worn down.
I had a similar experience with my Windstar - lots of pad material left, but still grinding after new pads & shoes. Turns out the rotors were bad. :( Btw, I just replaced the rotors without finding out if a simple turning would have eliminated the grinding.
