Is it necessary to press the brake when downshifting?

[Janice]

Downshifting does not necessarily require pressing the brake. Here is relevant information about braking: 1. Definition: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. The braking device is a mechanical braking device that can slow down the speed, also known as a decelerator. 2. Classification: Divided into emergency braking and daily braking. During emergency braking, be aware of the potential hazard of rear-end collisions from following vehicles.
