    en.wikipedia.org/wiki/Non-synchronous_transmission

    In 1891, the French Panhard et Levassor automobile used a three-speed manual transmission and is considered to have set the template for multi-speed manual transmissions in motor vehicles. [3] [4] This transmission used a sliding-gear design without any form of speed synchronization, causing frequent grinding of the gear teeth during gear ...

    Slowing the speed of the cars or keeping it in control on descending gradients, the motors worked as generators and braked the vehicles. The tram cars also had wheel brakes and track slipper brakes which could stop the tram should the electric braking systems fail.

    en.wikipedia.org/wiki/Brake_tester

    A roller brake tester is a method of allowing the dynamic assessment of the braking system of a motor vehicle, whilst the vehicle itself is in a static condition.This type of brake tester is normally used in UK garages when used as part of an inspection lane for the MOT test.

    Exhaust brakes are simpler in operation than an engine brake.Essentially, the exhaust pipe of the vehicle is restricted by a valve.This raises the pressure in the exhaust system, forcing the engine to work harder on the exhaust stroke of its cylinders, so again the engine is acting as an air compressor, with the power required to compress the air being withheld from the exhaust pipe, retarding ...

    Drum brakes generally can be found on older car and truck models. However, because of their low production cost, drum brake setups are also installed on the rear of some low-cost newer vehicles. Compared to modern disc brakes, drum brakes wear out faster due to their tendency to overheat.

  7. Dynamic braking - Wikipedia

    Norfolk Southern 5348 diesel-electric locomotive employs dynamic braking. The cooling grill for the brake grid resistors is at the top center of the locomotive. Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive.
