2. 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.

3. ECE Regulation 90 - Wikipedia

   en.wikipedia.org/wiki/ECE_Regulation_90

   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]

4. Eddy current brake - Wikipedia

   en.wikipedia.org/wiki/Eddy_current_brake

   Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...

5. 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]

6. Brake lining - Wikipedia

   en.wikipedia.org/wiki/Brake_lining

   The brake lining is that part of the brake pad which actually contacts the metal brake disc (rotor) when the brake is engaged. Using a typical bicycle brake as an example, the backing would be the metal shell which provides mechanical support, and the lining would be the rubbery portion which contacts the rims when the brakes are applied.

7. Disc brake - Wikipedia

   en.wikipedia.org/wiki/Disc_brake

   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]
