The high pitched squeaking noise you are hearing is the warning device telling you your brake pads are worn out and need replacing. The grinding sound is the sound you hear when you ignore the squeaking noise and allow your brake pads to wear so much that the metal backing of the pad is rubbing against the rotor. Replace all brake pads on the same axle and have the rotors turned at a machine shop. You may end up having to replace the rotors if they are damaged too severely.
It's probably the drive belt and they tend to make noise when they are getting stretched. You can either try tightening it, if it is able to be and not have a tensioner assy, or replace the belt.
Check your universal joints!
Sometimes squeaky noises can be a result of a damaged belt. When you speed up, the noise goes away. You should get your car inspected by a mechanic.
Check for a worn or loose drive belt.
