Start the Engine First or Release the Handbrake First?

[JacksonLee]

You need to step on the brake first; the order of ignition and handbrake release does not have much impact. Below is relevant information about the handbrake: 1. Principle: The professional term for the handbrake is auxiliary brake. Unlike the principle of the main brake, the handbrake uses a steel cable connected to the rear brake shoes to brake the vehicle. Long-term use of the handbrake will cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel will also increase. 2. Supporting Tools: The handbrake is used in conjunction with a return spring. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. With long-term use, the spring will also undergo corresponding deformation.
