  2. Brake pad - Wikipedia

    en.wikipedia.org/wiki/Brake_pad

    The concept of brake pads or disc brakes as an alternative to drum brakes had been around at least as early as a patent by F. W. Lanchester in 1902. [2] However, due to high cost and inefficiencies compared to drum brakes they were not commonly implemented until after World War II. [3]

  3. Brake lining - Wikipedia

    en.wikipedia.org/wiki/Brake_lining

    The dynamic friction coefficient "μ" for most standard brake pads is usually in the range of 0.35 to 0.42. This means that a force of 1000 Newtons on the pad will give a resulting brake force close to 400 Newtons. There are some racing pads that have a very high μ of 0.55 to 0.62 with excellent high-temperature behaviour.

    R90 calls for linings to be tested for speed sensitivity, cold performance, and replacement Brake pads and brake shoes are permitted to deviate from the frictional characteristics of their original-equipment counterparts by not more than 15%. [2] In addition, R90 requires tamper-evident, sealed packaging for replacement brake linings. [1]

    On automobiles, disc brakes are often located within the wheel A drilled motorcycle brake disc. The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed brakes that looked and operated similarly to a modern disc-brake system even though the disc was thin and a cable activated the brake pad. [4]
