A new disc brake noise damper has been developed which has displayed excellent performance characteristics over a wide range of temperature and pressure conditions. The product utilizes a precoated steel to form a high temperature resistant, three-layer composite by laminating steel to both sides of a specially developed core material.BRAKE NOISE, frequently perceived as high pitch sounds (squeal) emanating from the vehicle's brakes, continues to be an unsolved problem throughout the modern world markets.There are many theories as to the causes of brake noise, and extensive research is being conducted to find the primary contributors. Special design emphasis is being given to rotors, calipers, and shoe & lining assemblies. As yet, no solution has been found.The use of noise dampers, attached to the back side of disc brake shoes, is found to be an effective means of reducing brake noise. Their usage began in the late 1960's and early 1970's, with materials and construction varying greatly from application to application. A product, commonly referred to as “SAS”, was introduced in the early 1980's. Its improved performance characteristics resulted in it being considered state-of-the-art for the industry. However, temperature resistance, damping characteristics, and durability were still recognized as weaknesses.The objective was established to develop a new damper design which would display significant improvements in these areas. This paper will cover the process needed and used to meet this objective.
