The car braking system is divided into service brakes and parking brakes. Here are the detailed explanations: 1. Service brakes: Generally, all four wheels are braked together, but the braking force on the front and rear wheels may slightly differ. Braking either applies to the rear wheels or both front and rear wheels together. If the front wheels are not braked properly, there is a risk of strong inertial force causing the rear wheels to lift, leading to a rollover. 2. Parking brakes: Parking brakes commonly include hand brakes and foot brakes. The foot brake is the primary braking mechanism, and typically, all four wheels are braked together, ensuring the car neither jerks forward abruptly nor compromises safety and stability.

















I've been driving for many years, and every time I brake, I can feel the front of the car slightly sinking. This is because the braking system acts not only on the front wheels but also on the rear wheels. The front wheels handle most of the braking force, about 70%, due to weight transfer caused by the engine being in the front; the rear wheels provide balance to prevent skidding or fishtailing. If only the front wheels brake, the car becomes unstable and prone to losing control; if only the rear wheels brake, the stopping distance becomes too long, which is very dangerous. In actual driving, especially on wet and slippery roads during rainy days, the coordinated work of all four wheels ensures safe stopping. I regularly check the wear on the brake pads, and both front and rear brakes need to be well-maintained, otherwise, it affects overall performance. In short, modern cars are ingeniously designed to involve each wheel in braking, ensuring a smooth drive.

I enjoy working on my car myself and have disassembled many brake components, involving both front and rear wheel brake systems. When braking, all wheels participate in the process, with the front wheels handling 70% of the braking force using caliper discs or drum brakes, while the rear wheels manage the remaining portion. This design accounts for weight transfer during acceleration (rearward) and braking (forward), requiring coordinated effort from both axles for efficient deceleration. During brake pad replacements, I've observed that issues like rear wheel lock-up or excessive front pad wear can disrupt the entire system, such as causing ABS failure and uneven brake force distribution. Regular of both front and rear brake lines and fluid is crucial to prevent air ingress and potential failure. On actual roads, the coordinated braking of all four wheels significantly reduces accident risks, especially in congested urban traffic.

In the safety training course, I learned that the braking system is the core of vehicle protection, with both front and rear wheels braking to provide maximum stopping power. This design ensures body stability during emergency braking, preventing skidding or rollovers. ABS technology adjusts the braking force on each wheel to prevent wheel lock-up. If only some wheels are braked, it can lead to accidents, such as insufficient front-wheel braking causing loss of control. Any braking issues while driving should be repaired immediately, with maintaining front-rear balance being crucial. Regular inspection of brake discs and hydraulic systems can extend their lifespan.

When I first learned to drive, I also wondered about this issue. Later, I understood that all wheels participate during braking. Simply put, the engine at the front causes the weight to concentrate in the front, so the main braking force is on the front wheels, while the rear wheels help balance the stop. If they don't brake together, the car is prone to spinning during turns or sudden braking. In daily driving, both the front and rear brake pads and pumps need regular checks to maintain good condition. Driving in the rain makes it more obvious to see the wheels cooperating to ensure a safe stop. It's best to check the entire braking system once a year.

I find the evolution of automotive braking systems fascinating. Early vehicles might have only had rear-wheel brakes, but modern designs feature braking on all wheels. With technological advancements, four-wheel braking has become standard, as it efficiently distributes braking force and prevents excessive front-end dive. The engine's position affects the distribution between front and rear wheels, typically 70% front and 30% rear. ABS and electronic systems have further optimized balance. Regular , including checking brake fluid and aging lines, helps prevent issues. On the road, this design ensures smoother and more reliable stopping.
