Squealing noise as you turn or in gear slowing down..., anyone have had experience with their celica? Options

Basically, I heard it today while driving...I have had my axles changed almost a year ago and the only thing left that i need to do is change my brake pads, which i plan to do soon....I was driving down the streets when i suddenly heard a noise, squealing squeaky noise coming from my front right or left side of the car....i wasn't breaking but it sounded like the noise came from the rotors as if your brakes completely going out and the calipers are grinding on the rotor....the sound will only show up as i make a hard left turn (U-turn, slowly) or just in gear slowing down without pressing on the brake i can hear the squealing seemingly coming from the front rotors...should i just change my brake pads ( thus saying it is my brakes going out) and be okay, or it is something else? I thought stepping on the brake, if it squeals means the pads are out and that i need to change asap...? help??

no.,..this sounded like the noise of a rotors being grind by the calipers...when the brakes are out...only when i slow down and when i turn...i think it might be the bearings too...regardless, changing wheel bearings out of a 13 yr old car wouldn't be too bad of an idea either...it is rather old...
