2. Parking brake - Wikipedia

   en.wikipedia.org/wiki/Parking_brake

   In manual transmission vehicles, the parking brake is engaged to help keep the vehicle stationary while parked, especially if parked on an incline. [2] [3]While automatic transmission vehicles have a "Park" gear that immobilizes the transmission, it is still recommended to use the parking brake, as the parking pawl in the gearbox could fail due to stress or another vehicle striking the car ...

3. Drum brake - Wikipedia

   en.wikipedia.org/wiki/Drum_brake

   Brake shoes are typically made of two pieces of steel welded together. The friction material is either riveted to the lining table or attached with adhesive. The crescent-shaped piece is called the Web and contains holes and slots in different shapes for return springs, hold-down hardware, parking brake linkage and self-adjusting components.

4. 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.

5. Transmission brake - Wikipedia

   en.wikipedia.org/wiki/Transmission_brake

   The transmission brake is the yellow drum, to the right rear of the transfer box. A transmission brake or driveline parking brake is an inboard vehicle brake that is applied to the drivetrain rather than to the wheels. Historically, some early cars used transmission brakes as the normal driving brake and often had wheel brakes on only one axle ...

6. Air brake (road vehicle) - Wikipedia

   en.wikipedia.org/wiki/Air_brake_(road_vehicle)

   Truck air-actuated disc brake. An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to both release the parking/emergency brakes in order to move the vehicle, and also to apply pressure to the brake pads or brake shoes to slow and stop the vehicle.

7. Power brakes - Wikipedia

   en.wikipedia.org/wiki/Power_brakes

   The activation of this piston will allow two brake shoes located within the drum of the brake to expand, thus generating friction to slow down and stop the wheel. Usually, this brake is located in the rear wheels of the vehicle, while the disc brake is located at the front of the vehicle.
