Car brakes apply to all four wheels simultaneously. Below are the working principles of brakes and precautions for brake usage: Brake Working Principles: When the driver presses the brake pedal, brake fluid travels through the master cylinder and brake lines to reach the wheel cylinders. At this point, the brake calipers tighten, causing the brake pads inside to firmly clamp the brake discs, which gradually brings the wheels to a stop. Precautions for Brake Usage: During long-distance braking, it is essential to assess the road conditions ahead and adjust braking according to factors such as distance and speed. When driving in rainy conditions, while paying attention to controlling speed, one must also use brakes cautiously to avoid skidding.

When driving, I noticed that the braking system indeed applies brakes to all four wheels simultaneously. This is because the design uses a hydraulic or oil-pressure system to evenly distribute force to each wheel. When you press the brake pedal, the master cylinder pressurizes, and the fluid travels through pipelines to the brake calipers or drum brake mechanisms at each wheel, ensuring the vehicle stops smoothly and avoids skidding. However, modern cars are equipped with ABS (Anti-lock Braking System), which intelligently adjusts the braking force on each wheel during emergency braking or slippery conditions, such as briefly releasing a wheel to prevent lock-up. This design significantly enhances safety, especially when driving in rain or snow. I always feel the brakes are synchronized when driving, but I recommend checking the brake fluid and brake pads every six months to ensure the system remains in good condition.

The principle of car braking is actually a hydraulic transmission mechanism. When the brake pedal is pressed, the master cylinder generates pressure, and the fluid synchronously pushes the braking devices of all four wheels through the pipelines, so in principle, all four wheels brake simultaneously. The ABS system monitors wheel speed sensors and briefly interrupts the braking of individual wheels during emergency braking to prevent lock-up and skidding. Both disc brakes and drum brakes operate on a similar structure, with modern vehicles also utilizing electronic power assistance to enhance response time. From my experience, this design ensures balanced braking and reduces stopping distance, but regular maintenance of brake discs and wheel speed sensors is essential.

I understand that the braking system typically applies brakes to all four wheels simultaneously, thanks to unified hydraulic control. ABS intervenes at critical moments, such as adjusting the braking force on wheels on slippery surfaces to prevent loss of control. This significantly reduces the risk of accidents, especially during high-speed emergency braking. Regular inspection of brake components can prevent imbalance issues caused by malfunctions, ensuring efficient and reliable braking every time.
