BRAKE NOISE

This article describes disc brake squeal as a noise that occurs at the upper range of human hearing which many but not all people with apparently normal hearing can hear. Research at Bendix Corporation employs sophisticated aural testing equipment to isolate, identify and measure brake noises. Tests show that the noise source is the entire system, including the friction material, pad shape, and configuration of the caliper and rotor. Squeal has been reduced by switching the friction material, altering the pad shape, and cutting slots in the rotor. An insert with this article is entitled "Rotor's composition can lower noise, wear."
