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 with a parking pawl that immobilizes the transmission, it is still recommended to use the parking brake, as the pawl in the gearbox could fail due to stress or another vehicle striking ...
Interior of an automatic transmission, showing the toothed locking wheel and the pawl below it; a finger is touching the pawl. A parking pawl is a device fitted to a motor vehicle's automatic transmission that locks up the transmission when the transmission shift lever selector is placed in the Park position.
The driver starts by using steering input to transfer weight to the outside tires; the handbrake is then used to lock the rear wheels, thus upsetting the adhesion between the tires and the road surface. With practice, the car can be placed accurately by releasing the handbrake and accelerating the vehicle. [1]
A traditional method of hill starts in a manual transmission car is to use the parking brake (also called "handbrake", "emergency brake", or "e-brake") to hold the vehicle stationary. This means that the driver's right foot is not needed to operate the brake pedal, freeing it up to be used on the accelerator pedal instead.
Pawl transmission brake, inside an automatic transmission. A form of transmission brake is commonly fitted to automatic transmissions. These brakes use a dog clutch or pawl system, rather than friction linings. They thus provide a simple and positive lock when stationary, but cannot (or at least, should not) be engaged when moving.
Electric park brake in the center console in a Volkswagen Golf Variant. An electronic parking brake (EPB), also known as an electric parking brake or electric park brake, is an electronically controlled parking brake, whereby the driver activates the holding mechanism with a button and the brake pads are electrically applied to the rear wheels.

The maximum brake force available to the engine driver from the conventional braking system, usually operated by taking the brake handle to its furthest position, through a gate mechanism, or by pushing a separate plunger in the cab.
Pontiac Trans Am burnout with line locks. A line lock is a device that allows the front brakes to lock independently of the rear brakes via a switch. [1] [2] [3] The device is an electric solenoid that controls a valve which allows the brakes to be controlled individually. This allows the front brakes to be locked and the rear brakes to be open ...
