Can You Pull the Handbrake While Driving?
1 Answers
When the handbrake is suddenly pulled to the locked position while the car is in motion, the consequences vary depending on the type of handbrake. A mechanical handbrake may cause the car to lose control, whereas an electronic handbrake can allow the car to decelerate normally. Structure and Working Principle of Mechanical Handbrake: The structure and working principle of a mechanical handbrake are quite simple. It utilizes a lever mechanism where a handle pulls a steel cable, causing the brake pads of the two rear wheels to clamp tightly against the brake discs (or drums), generating braking force. It's important to note that a mechanical handbrake only brakes the two rear wheels, leaving the front wheels without braking force. In this scenario, the rear wheels lock up and skid along the ground. Under the most ideal conditions, the car will continue in a straight line, gradually decelerating until it comes to a stop. Consequences of Emergency Braking: If the car is traveling at high speed in a straight line and the handbrake is pulled, the braking force of the handbrake may not be very strong, but it still provides some braking effect. However, it would require a long distance to come to a complete stop. Even a slight turn of the steering wheel at this point can cause the car to fishtail or even roll over, leading to a loss of control, which is extremely dangerous. If you must use the handbrake at high speed, avoid pulling it all the way to the locked position at once. Instead, mimic the working method of ABS by pulling and releasing the handbrake intermittently, which can significantly improve safety.
