When downshifting a manual transmission car, you need to choose whether to press the clutch or brake first based on the vehicle's speed. Here are the relevant details: 1. When the car is moving at low speed, pressing the brake directly may easily cause the engine to stall, so you should press the clutch first to prevent the engine from stopping; 2. When the vehicle is moving at high speed, you should press the brake first because the engine is running at a higher speed and has inertia. In this case, you should use a gentle tapping brake method to slow the car down—avoid pressing too hard—and then press the clutch to prevent the car from stalling.

When I first learned to drive a manual transmission car, I was quite confused about this issue. My instructor repeatedly emphasized that downshifting must always involve braking first to reduce speed, then pressing the clutch to shift gears. If you press the clutch before braking, the car will continue coasting or even accelerate, especially during turns or downhill sections, potentially leading to loss of control. During practice, I tried it a few times and found that braking first to reduce speed to match the lower gear's range—for example, slowing to 20 km/h before downshifting to second gear—made the whole process much smoother. Later, I developed this habit: gently braking to gradually reduce speed before every downshift, ensuring safety before operating the clutch. This made driving much easier and more confident.

Having driven manual transmission cars in the city for over a decade, I've grown accustomed to this operating sequence: first gently apply the brakes to decelerate to an appropriate speed, then press the clutch to shift into a lower gear. If you skip steps and press the clutch first, the car loses engine braking force, making the wheels prone to skidding when freely rolling – I've had some close calls especially during rainy days or on steep slopes. In daily driving scenarios like preparing for turns or stopping, always brake first to reduce speed to the 20-30 km/h range, then engage the clutch for gear shifting. This seamless sequence allows for proper engine braking cooperation, ensuring more stable driving. Remembering this order keeps your driving safer.

From a safety perspective, I always insist on pressing the brake pedal first to slow down before operating the clutch to downshift while driving. Not doing so carries high risks—directly depressing the clutch would cause the vehicle to lose engine braking traction, potentially leading to unintended acceleration or rollback, especially on slippery roads or sharp turns, which could easily trigger accidents. I once heard a friend share a close call where improper operation nearly caused a rear-end collision, so developing good habits is crucial: When you need to decelerate and downshift, gently press the brake pedal first, and only shift gears after the speed has sufficiently dropped—safety always comes first.
