While the high-pitched whine of squealing brakes will surely grab your attention, in most cases that squeal is actually an intentional feature, rather than the indication of a problem. On your brake pads, metal pins stick out partially over the pad material, facing the brake rotor. When the brake pads become worn to a certain point, that pin will begin rubbing on the spinning brake rotor, causing that familiar squealing noise. It isn't a cause for panic, but you'll definitely want to make your appointment to visit our service center from Philadelphia or Deptford to have your brake pads replaced before they become too badly worn.
