Occasional groaning or squealing sounds from the disc brakes are usually caused by vibration being transmitted through the brake pads. Brake friction materials that contain little or no asbestos may contribute to brake noise. These noises are normal and rarely indicate a problem.
Although there is no single solution to brake noise problems, proper maintenance and repair can help minimize noise. Disc brake caliper assemblies include anti-rattle springs to minimize vibration and noise. Brake pads and calipers should be kept clean and free of corrosion. Always resurface or replace brake rotors when changing brake pads.
