When starting in Driving Test Level 3, you do not need to press the brake while engaging the clutch. The functions of the clutch are: 1. Gradually increasing the driving force of the car to ensure a smooth start; 2. Temporarily separating the engine and transmission for gear shifting; 3. Preventing overload in the transmission system; 4. Reducing torsional vibration impacts from the engine to prolong the lifespan of transmission gears. The function of the brake is to reduce speed or bring the vehicle to a stop. Its working principle involves converting the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and brake drum, as well as between the tires and the ground, thereby slowing down or stopping the vehicle. The working principle of the clutch is: 1. When the inner ring is fixed, the outer ring can rotate freely in the clockwise direction without locking the wedge block; 2. When the outer ring rotates counterclockwise, the wedge block locks, preventing the outer ring from rotating.
