Loose or worn belt(s).
check a/c compressor and belt.
When refilling the oil some may have dripped onto the belt which would cause it to start slipping badly and squealing loudly.
Yes.Equally likely is if the belt is much more than 3-4 years, the material is glazing over or hardening, which is another common cause of squealing.
It sounds like the fan-belt is slipping.
possibly a bad brake...you should get all brakes done
throw-out bearing going bad is my guess
it could be that your brakes are dirty or that you need new pads
