2. Power brakes - Wikipedia

   en.wikipedia.org/wiki/Power_brakes

   Vacuum boosters provide brake assist for the driver by multiplying the force out of the booster creating more than the force that was used to push on the brake pedal. The booster works by pulling the air out of the booster chamber with a pump or other vacuum source (typically the engine's intake manifold [1]), creating a low-pressure system ...

3. Regenerative braking - Wikipedia

   Mechanism for regenerative brake on the roof of a Škoda Astra tram The S7/8 Stock on the London Underground can return around 20% of its energy usage to the power supply. [ 1 ] Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that ...

4. Electric fence - Wikipedia

   en.wikipedia.org/wiki/Electric_fence

   Charger for a plus-minus net fence. An electric fence is a barrier that uses electric shocks to deter people and other animals [note 1] from crossing a boundary. The voltage of the shocks may cause discomfort or death. Most electric fences are used for agricultural purposes and other non-human animal control.

5. Electric friction brake - Wikipedia

   The first brake shoe then tries to follow the rotation while asserting friction and thereby propagate the movement onto the second brake shoe through the adjuster which also pushes against the drum. The friction force is then caught by the stopper (Black trapezoid) mounted on the brake shield.

7. 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]
