What is the difference between P gear and handbrake?

[AaronLynn]

The difference between P gear and handbrake is that when P gear is engaged, the transmission lock mechanism works, while when the handbrake is pulled during parking, the rear brakes work. Here is more information about gear shifting: 1. For long-term parking, you need to first engage P gear and then pull the handbrake, whether it is an electronic handbrake or a mechanical handbrake. 2. If you only engage P gear without pulling the handbrake when parking, parking the car on a slope will put a lot of pressure on the transmission's gear locking mechanism, which may seriously cause damage or oil leakage to the transmission, and there is a high probability of the car rolling away. On the other hand, parking with only the handbrake pulled without engaging P gear will leave the vehicle's transmission in a separated state, which also has a high chance of causing the car to roll away.
