Should I Shift Gear or Release the Handbrake First in Driving Test Part 3?
1 Answers
You should shift gear first and then release the handbrake. The reasons are as follows: 1. This sequence is primarily for safety considerations. After engaging the gear, the power transmission path in the transmission is connected. When first shifting into gear, the transmission is in first gear, which provides the highest torque. If the brake is not properly applied, the car may suddenly lurch forward. 2. Engaging the gear without releasing the handbrake means all the power output by the engine will be absorbed by the torque converter, causing its temperature to rise sharply. Prolonged operation in this state can damage the torque converter. 3. For dual-clutch transmissions, after engaging the gear, the clutch friction plates will be in a semi-engaged state. Prolonged semi-engagement can lead to burning of the friction plates, so it's necessary to start moving as soon as possible.
