  2. Brake lining - Wikipedia

    en.wikipedia.org/wiki/Brake_lining

    The first asbestos brake linings were developed in 1908 by Herbert Frood. [1] Although Frood was the first to implement the use of asbestos brake linings, the heat dissipation properties of the fibres were tested by various scientists, including materials chemist Gwilym Price, who did most of his research and testing at Cambridge, United ...

  3. Brake pad - Wikipedia

    en.wikipedia.org/wiki/Brake_pad

    However, as the serious health-related hazards of asbestos eventually started to become apparent, other materials had to be found. Asbestos brake pads have largely been replaced by non-asbestos organic (NAO) materials in first world countries. [9] Today, brake pad materials are classified into one of four principal categories, as follows:

  4. WVA number - Wikipedia

    en.wikipedia.org/wiki/WVA_number

    WVA numbers (Waren-Vertriebs-Artikel-Nummern) are a reference and assignment system for brake linings, clutch facings, brake shoes and other friction materials which will especially be used in road vehicles but also in mechanical engineering.

  5. Vermiculite - Wikipedia

    en.wikipedia.org/wiki/Vermiculite

    Finer grades of exfoliated vermiculite are being used in brake linings primarily for the automotive market. The properties of vermiculite that make it an appropriate choice for use in brake linings include its thermal resistance, ease of addition to other raw materials to achieve a homogeneous mix, and its shape and surface characteristics.

    Mac's Spring & Brake Service shop, with Raybestos brakes (ca. 1930-1945). In 1906, Raymond and Law invented the woven brake lining, an important innovation in automotive brakes. From 1919 to 1989 Raybestos brand was manufactured by Raymark Industries, Inc, of Stratford, Connecticut. Raymark Industries filed for Chapter 11 bankruptcy in 1998. [2]

  8. Graphite - Wikipedia

    en.wikipedia.org/wiki/Graphite

    Natural amorphous and fine flake graphite are used in brake linings or brake shoes for heavier (nonautomotive) vehicles, and became important with the need to substitute for asbestos. This use has been important for quite some time, but nonasbestos organic (NAO) compositions are beginning to reduce graphite's market share.
