2. 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]

3. Electronically controlled pneumatic brakes - Wikipedia

   en.wikipedia.org/wiki/Electronically_controlled...

   When the brake pipe and car components are charged with air, the brakes release. When the engineer needs to make a brake application, control valves in the locomotive reduce the brake pipe pressure. As the brake pipe pressure is reduced, the service portions on each car divert air from their reservoirs to their brake cylinders.

4. Electro-pneumatic brake system on British railway trains

   en.wikipedia.org/wiki/Electro-pneumatic_brake...

   The first Southern units fitted with EP brake could be considered the Bulleid double deck 4-DDs built 1949 (4001 & 4002). The EP brake fitted to this stock was not of the self lapping type and still required the Westinghouse brake as the 'fail to safe' braking as the EP brake fitted was of the 'energise to apply' type, which meant if there was a loss of brake control voltage the EP brake was ...

5. Electronically controlled brake - Wikipedia

   Electronically controlled brake (ECB) developed by Toyota Motor Corporation initially for its hybrid and Lexus models, is the world's first production brake-by-wire braking system. [1] The ECB went on sale in Japan in June 2001, [ 2 ] first appearing on the Toyota Estima hybrid (first generation), [ 3 ] and making its North American debut with ...

6. 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 ...

7. 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.
