The brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors. The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).Google+

Dealer talked into replacing the front pads & rotors, ? if they really needed to be replaced. To the tune of about $500.00 as I recall.
They worked fine for about six months & stated to grind, squeal, & etc., plus the dust & dirt was just terrible. After about six months of flushing the nasty waste product that was suppose to be OEM pads & rotor out & off the wheels, I replaced them with an aftermarket set that have been just great for the past two & a half years. I am currently in OH & the above all happened in CA with no salt or other chemicals that might be associated to cause extra problems.
bad squeel, lots of brake dust. Brakes replaced.
