I thought the indicators squeal when you press the brakes...You can look at the brakes and easily tell if its the wear indicator. If its touching the rotor, its time for brakes. A lot of times those wear indicators need adjustment. Ive seen them on several occasions start contacting the rotor before the brakes are even half worn down.

Maybe sombody put brakes on it and didnt put that brake lube on them. if thats the case that would explain the brake chatter haulting when you apply the brakes.
