I assume your pads are squealing. GM puts a wear indicator on the pads and they start rubbing the rotor and make an anoying noise when you push the brakes. If you let them go, they start rubbing all the time and your pads wear down to bare metal. the rotors will be gouged, sometimes so badly they can't be turned and you wind up replacing both pads and rotors. I see people put pads on and do nothing else, and, if you are real lucky you can too. But, usually the rotors are uneven and sometimes too thin if old so they need to be trued(turned) if still thick enough, or replaced. Can be dangerous to let them go, as the front brakes do most of the stopping. On Ford Explorers, the darn pads can actually fall out if run too long(I saw this happen). Get em' fixed, do not delay!!!
