What happens when you pull the handbrake while in D gear on an automatic transmission?

[EvelynDella]

In a car, the D gear is the driving gear and should not be used with the handbrake. Forcing the car to stop by pulling the handbrake can reduce the engine's lifespan and potentially cause damage. Below is relevant information about the handbrake: Shortened lifespan of the handbrake cable: The handbrake cable appears as a solid steel cable externally, but inside, it contains nylon material, which plays a crucial role. Continuously pulling the handbrake tightly will gradually cause the nylon material to lose elasticity, ultimately rendering it ineffective. Failure of the handbrake return spring: Frequently using the handbrake at 100% force keeps the return spring under high tension, which over time can cause it to lose its ability to return to position.
