It depends on the actual situation and urgency. Below are the relevant scenarios: If the goal is to control speed: Generally, there is no need to press the clutch; instead, you can utilize engine braking by releasing the accelerator to assist in deceleration, which helps reduce brake pad wear and lower the temperature of the braking system. Moreover, using engine braking is smoother than applying the brakes, making it less likely to cause skidding or loss of control. If it's an emergency situation: To stop the vehicle as quickly as possible, press both the clutch and brake pedals fully (at this point, the ABS anti-lock braking system will activate, and if equipped with a brake force distribution system, safety will be significantly improved). Simultaneously, grip the steering wheel firmly to avoid loss of control or rollover due to sudden steering movements.

You definitely need to apply the brakes appropriately when going downhill, especially when I'm driving on mountain roads. Although the engine brake helps slow the car down, when encountering sharp turns or sudden deceleration of the car ahead, relying solely on downshifting is simply not fast enough. Every time I descend a long slope, I lightly tap the brakes to control the speed while keeping an eye on whether the brakes feel soft or get hot. If I smell burning, I immediately pull over to let them cool down. Once, while driving a manual transmission car downhill in Guizhou, I found that using third gear combined with intermittent braking was the safest approach. If you keep the brakes pressed continuously from start to finish, the brake discs can even turn red from overheating. Remember, safety on a downhill is a hundred times more important than saving brake pads.

Downhill braking depends on the situation. For small slopes on urban viaducts, I usually just release the throttle in D gear, but last year's self-drive trip to Western Sichuan truly taught me the severity of long descents. On a continuous 20-kilometer steep slope, you must learn to use S gear or manual mode to downshift and control speed. Braking should be like playing the piano—gentle taps to maintain distance while preventing brake overheating and failure. Be extra cautious in snowy conditions; even light braking can cause skidding, so it's best to reduce speed in advance. As seasoned drivers say, the life of your brakes matters too.

Let me tell you, going downhill without braking is pure recklessness. A while ago, I was driving my friend's SUV on a mountain road and tried relying solely on engine braking when taking a curve without pressing the brake. The speed kept increasing, and I almost went over the guardrail. Now I've developed a habit: when I see a downhill sign, I downshift in advance and rest my right foot lightly on the brake pedal. For long downhill stretches of five kilometers or more, I lightly press the brake for five seconds every two minutes to cool it down. I remember my driving instructor repeatedly emphasized during the license test: it's better to replace brake pads more often than to joke about brake failure.

I have personal experience with braking on downhill slopes. Last year, while driving a manual transmission car through the Qinling Mountains, I tried controlling the speed entirely in second gear over a 10-kilometer descent. The engine roared, but the speed still soared to 70 km/h. Quickly, I changed my strategy: coasting in third gear on straight sections and lightly tapping the brakes before entering curves. Now, driving an automatic transmission car is even simpler—just shift to L gear or sport mode to let the transmission hold back the speed. There are really only three situations where you need to press the brakes: sharp turns, closing gaps with other vehicles, or sudden bumps on the road. Mastering the rhythm is far more important than stomping on the brakes.

Controlling speed downhill is essential, but relying solely on brakes is absolutely wrong. Once, while delivering goods in a small truck downhill, the brake pedal went soft in less than five minutes, forcing me to pull over for a twenty-minute break. Now I've learned: on long descents, using cruise control to limit top speed combined with intermittent braking works best. In heavy rain or on gravel roads, cancel cruise control and switch to downshifting with early, gentle braking. Remember, brake lights are also warning signals for vehicles behind—don't hesitate to use them. Regularly checking brake pad thickness is even more critical.
