Yes, emergency braking without depressing the clutch may have the following potential impacts, with explanations as follows: 1. ABS Affected: Without depressing the clutch, the engine's drag torque may interfere with the normal operation of the ABS system, potentially affecting control in extreme cases. 2. Engine Stall: Braking without depressing the clutch can cause the engine to stall. Although the braking distance remains unchanged, there is still a risk of secondary accidents after coming to a stop, which is also a safety hazard. 3. Possible Misoperation: In emergency situations, people are highly stressed, especially those with poor mechanical operation skills. In a panic, they may misoperate the pedals. If both the brake and clutch are depressed simultaneously, even accidentally pressing the accelerator will not affect the braking effectiveness.

As a seasoned driver with decades of experience driving manual transmission cars, I always have to think about whether to press the clutch when encountering deceleration situations. Generally speaking, when braking to slow down, there's no need to press the clutch at the same time, unless the speed drops very low and the engine is about to stall. For example, when slowing down to enter a curve during normal driving, I only need to press the brake, and the engine will help with braking, saving fuel and ensuring safety. Pressing the clutch disconnects the power, causing the engine to idle and waste fuel, while also accelerating clutch wear. In related situations, such as traffic jams or frequent braking, pay attention to the tachometer and only press the clutch when the RPM drops below 1000 to avoid stalling. Developing this habit can extend the life of your car and reduce accidents. In short, control your speed without frequently using the clutch, and it's best to practice sensing the speed and shifting timing more.

When I was learning to drive, I often struggled with this issue. The instructor repeatedly emphasized that when slowing down, just press the brake pedal and avoid touching the clutch unless coming to a complete stop. Depressing the clutch disengages the engine, which can result in slower deceleration and potentially increased fuel consumption, especially when going downhill at high speeds—rely on the brakes for braking. Through experience, I found that when the speed is above 20 km/h, using only the brake allows the engine to assist in braking, helping the car stop more quickly. Randomly pressing the clutch may damage the transmission or cause gear-shifting issues. Additionally, beginners should avoid over-focusing on the clutch and instead prioritize brake control and maintaining good visibility. It's advisable to practice deceleration scenarios in a training area to get accustomed to operating only the brakes, which will eventually become second nature.

From a mechanical perspective, there's no need to depress the clutch when braking to decelerate. The clutch serves to switch power connection. During deceleration, the engine is still operating, and depressing the clutch disengages the drive, which can cause RPM fluctuations and potentially harm the engine. I only engage the clutch at low RPM before coming to a complete stop to prevent stalling. In daily driving, braking for deceleration relies entirely on the brake system for higher efficiency. Relatedly, frequent clutch usage accelerates wear and affects transmission lifespan. The simple rule is: use brakes more and manipulate the clutch less.
