most likely a loose belt.. Try to tighten you fan belt, if that does not work one of the parts it turns may be starting to break (alt., water pump, Power Steering, ect.) in which case they most likely will start to make a noise before completely breaking down.. So also try to see if any of them make any sound after the squeling stops, if so that part will need replaceing at so point soon to avoid it breaking you down at the wrong moment or place. (The noise you asking about is that black belt turning at a different speed than one of the wheels it turns meaning its too loose or one of those wheels is not turning as fast as it should) also a smell of the rubber melting under the hood is a sign to fix it quick before the belt melts enough to snap..
The breaks slow the car down meaning that the motor and belt is not moving as fast or hard, so the noise dies down
If your car makes a squealing sound when you are turning it is because your brakes have worn out. When the brakes wear down below a certain point, a wire pops loose. That makes a squeaking sound.
Your brake system needs repair immediately. The brakes are squealing because the pads are worn out, and you are hearing the warning device or the metal to metal contact of the pad and rotor. Stop driving the car and have the brakes repaired. The ABS light may or may not go out. If it does not, there is problem with the ABS. Your standard brakes will still work.
have brakes check
When the brake pads are worn the rivets will actually touch the brake rotor when the brakes are applied. The brakes should be changed immediately.
Have the brakes checked.
If you hear the squealing when applying the brakes, the pads are worn out and need replacing ASAP. Failure to replace the pads immediately will result in worn out rotors which will also need replacing. If the squealing noise is not when braking it may be a worn drive belt.
"Squealing" is usually from the belt or brakes. use belt conditioner to stop a squealing belt.(usually sold at walmart) you can probably figure out how to stop squealing brakes. but if not they need to be replaced. people need to start reading those owners manuals the car comes with.
You should have your brakes cleaned! Or have a mechanic look to make sure nothing is wrong. My neon does this and after driving a while it stops. Sometimes rust,dust and dirt particals get on the drums !!
The low brake indicators on the brake pads are squealing. I highly recommend you have the brakes checked out.
check your wheel bearings
The squealing sound in brakes is caused by dust and dirt in the brakes. Also, more commonly, it is caused by worn pads or shoes. On disk brakes there is a wear indicator. This will rub against the disk and squeel when brake pads are worn to where they need replacing.
