Will pulling the handbrake too hard damage it?
2 Answers
Yes. The handbrake should not be pulled too high: When applying the handbrake, pulling it to 70% of its height is sufficient. Fully engaging the handbrake and pulling it to 70% of its height provide the same braking effect. However, keeping the handbrake fully engaged for a long time can reduce the responsiveness of the handbrake cable and shorten its lifespan. Additional Information: Notes: The purpose of the handbrake is to keep the vehicle stationary, preventing it from moving or rolling, thereby achieving a stable state. However, pulling the handbrake to its maximum is not scientifically advisable. Generally, pulling it to 70%-80% is sufficient. During high-speed driving, directly pulling the handbrake is extremely dangerous. The handbrake primarily affects the rear wheels, and pulling it suddenly can cause the rear wheels to lock, leading to skidding or even a rollover. In snowy or icy conditions, when the ice and snow melt, they may cover the handbrake cable and freeze again. Once frozen, the handbrake cannot be released, making the vehicle unable to move. In extreme weather conditions, using the gear and obstacles for parking is a better solution. The most ideal approach is to find a flat parking spot.
I've been driving for almost 20 years and have a good understanding of car mechanics. Pulling the handbrake too high can indeed damage components, especially the brake cable. The brake cable is designed with some elasticity, but excessive force can stretch it beyond its normal range, which over time may cause it to loosen or break. The brake drum or brake pads may also wear out faster, just like metal being stretched and deformed. Once, when I went to the repair shop, the technician said many car owners tend to pull the handbrake as hard as possible when parking, resulting in the system failing quickly and needing replacement parts. Now, I only pull it with moderate force—just enough to hear a few clicks and ensure the car is stable before stopping. Pulling it too tight can also cause it to freeze and stick in icy conditions. I recommend regular checks of the brake system, maintaining appropriate tension, and avoiding unnecessary expenses. In safe driving, the handbrake is an auxiliary tool for parking, not a test of strength.
