What are the brake and accelerator of a car?

The brake of a car, also known as the braking system, refers to the action that stops or reduces the speed of a running locomotive, vehicle, or other transportation tools or machinery. It is divided into: 1. Drum brake: A semi-circular brake shoe is installed inside the wheel hub, and the lever principle is used to push the brake shoe to make contact with the inner surface of the drum, causing friction; 2. Disc brake: The brake caliper controls the brake pads to clamp the brake disc on the wheel. The accelerator of a car, also known as the throttle or throttle valve, is part of the car's fuel supply system. By controlling the amount of pedal pressure, it regulates the opening of the engine's throttle valve, controls the air intake, and the computer controls the fuel amount, thereby controlling the engine's speed.
After driving for over a decade, I've realized that the accelerator and brake are the two most fundamental control pedals in a car. The accelerator is on the right – a gentle press increases the engine RPM, making the car move. Essentially, it controls the amount of fuel-air mixture entering the engine, with more power resulting in higher speed. The brake is positioned to the left of the accelerator, closer to the center. Pressing it directly slows the wheels by using hydraulic pressure to clamp the brake pads against the rotors. Both pedals are operated by the right foot, with the heel planted and the toes pivoting to switch between them. Beginners should avoid driving in thick-soled shoes, as imprecise pedal control can be dangerous. Regularly check brake pad wear; if they're too thin, stopping distance increases. On rainy days when roads are slippery, brake earlier and more gently to avoid skidding from sudden hard stops. Experienced drivers know that smooth operation of the accelerator and brake ensures both safety and fuel efficiency.
