2. Line lock - Wikipedia

   en.wikipedia.org/wiki/Line_lock

   For parking using the brakes on all four wheels, two valves may be necessary. Any leakage at the brake cylinders will reduce pressure in the line and release the brakes. For this reason, line locks should only be used temporarily. [6] Parking brakes using disc brakes do not have the same issues as drum brakes, but a vehicle needing parking ...

3. Parking brake - Wikipedia

   en.wikipedia.org/wiki/Parking_brake

   The parking brake would ensure the car is secure, should another vehicle come into physical contact from behind, causing the car to jolt forward. [15] It is not recommended to use the parking brake when the vehicle is in-motion, unless there is a problem with the main brakes, as this can lock the back wheels and cause a skid. [16]

4. Drum brake - Wikipedia

   en.wikipedia.org/wiki/Drum_brake

   Many rear disc braking systems use a parking brake in which the piston in the caliper is actuated by a cam or screw. This compresses the pads against the rotor. However, this type of system becomes much more complicated when the rear disc brakes use fixed, multi-piston calipers. In this situation, a small drum is usually fitted within or as ...

5. 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.

6. Emergency brake - Wikipedia

   en.wikipedia.org/wiki/Emergency_brake

   Advanced emergency braking system, where brakes are applied automatically in case of emergency; Emergency brake assist (EBA or BA), which increases braking effectiveness when a human driver executes a panic stop; Parking brake or hand brake in automobiles, which can also be used in case of failure of the main braking system

7. Automated emergency braking system - Wikipedia

   en.wikipedia.org/wiki/Automated_emergency...

   Emergency: the system will intervene only in a critical situation. Braking: the system tries to avoid the accident by applying the brakes. Time-to-collision could be a way to choose which avoidance method (braking or steering) is most appropriate. [6] A collision avoidance system by steering is a new concept.
