What is the difference between the brake pedal and the parking brake?

"The parking brake refers to the handbrake, while the brake pedal is the foot brake, commonly known as the main brake. Below is an introduction to the differences between the brake pedal and the parking brake: Emergency braking is primarily distinguished from anticipatory braking: It refers to immediately applying the brakes upon encountering an emergency situation to bring the vehicle to a stop in the shortest possible time. Engine braking involves using the engine's resistance to slow down the vehicle, such as when descending a long slope. Prolonged use of the foot brake can cause the brake pads to overheat and fail, so shifting to a lower gear and idling can help control speed using the engine's resistance. The usage scenarios for the two differ: The brake is essentially the main braking system. Brakes are divided into service brakes (foot brake) and parking brakes (handbrake). During driving, the service brake (foot brake) is typically used to slow down or stop the vehicle while moving forward. It is not just for keeping the car stationary. The parking brake is only used when the service brake fails. Once the vehicle is stationary, the parking brake (handbrake) is engaged to prevent the vehicle from rolling forward or backward. After parking, in addition to using the parking brake, it is advisable to shift into first gear when on an uphill slope (to prevent rolling backward) and into reverse gear when on a downhill slope (to prevent rolling forward)."
After driving for so many years, I often encounter people asking about the difference between the brake pedal and the parking brake. Simply put, the brake pedal is the one you press with your right foot to slow down or stop the car while driving. It's connected to the hydraulic system, and pressing it slows or stops the vehicle, used for controlling speed during motion. The parking brake, commonly known as the handbrake, is used after parking and turning off the engine to prevent the car from rolling, especially on hills or uneven surfaces where it's essential for securing the vehicle. I recall parking my old car on a steep slope—relying solely on the gear wasn't enough; I had to pull the handbrake tight to avoid the car sliding and causing an accident. Beginners often confuse these, sometimes engaging the handbrake while moving, which can lock the tires and be extremely dangerous. My advice to fellow drivers: use the brake pedal to slow down while driving; always engage the parking brake when parked, and regularly check the brake pads and cables to ensure driving safety.
As a car enthusiast, I pay close attention to these mechanical details. The brake pedal is part of the hydraulic system - when pressed, hydraulic pressure is transmitted to the wheel calipers which clamp the brake rotors to decelerate, allowing dynamic speed control. The parking brake, however, is an independent system. Older vehicles use a hand-pulled cable to lock the rear wheels, while newer models mostly feature electronic button-activated automatic locking, primarily designed to prevent vehicle movement after parking. The key distinction lies in their purposes: one is designed for dynamic use with quick response, while the other serves as a static securing device. Here's a useful tip: Applying the parking brake while driving can cause minor damage like tire and brake pad wear, or in severe cases lead to skidding and loss of control. Conversely, not engaging the parking brake when parked means even the P gear won't prevent rolling on slopes. I recommend checking both hydraulic fluid and parking brake cables during every vehicle maintenance to ensure both systems function properly for safety.
