Will There Be Any Problem If I Step on the Accelerator While the Handbrake Is On?
2 Answers
Stepping on the accelerator while the handbrake is on can have negative effects, causing significant damage to the brake discs and leading to severe shaking of the engine and transmission. Damage to Brake Discs: During this time, the vehicle's wheels continue to rotate, and the brake discs remain engaged, creating intense friction between the wheels and the brake discs. This generates heat, shortening the lifespan of the brake discs and pads, and may even pose a fire hazard. Vehicle Shaking: Since the vehicle's power cannot be effectively transferred, the engine and transmission experience severe vibrations. During this shaking, various components undergo intense friction, creating potential hazards. Therefore, stepping on the accelerator with the handbrake engaged is highly discouraged. Handbrake Usage Tips: The handbrake is often used in conjunction with neutral gear; avoid pulling the handbrake too tightly, and always engage it when parking after turning off the engine; avoid parking on slopes for extended periods; do not pull the handbrake while driving at high speeds; ensure the handbrake is fully released before starting the vehicle; in snowy or icy conditions, release the handbrake slowly and move the vehicle gradually.
A friend of mine once did the same thing, and the car suddenly lurched forward with a terrifying noise. The parking brake works by locking the rear wheels through hard friction between the brake pads and the wheel hub. When you step on the gas, the engine tries its hardest to transfer power to the drive wheels, resulting in a tug-of-war between the two. The brake pads are bound to lose a layer of material, and in severe cases, you might even smell burning. The handbrake cable can also be forcibly stretched and deformed. This is especially damaging for rear-wheel-drive cars, and while all-wheel-drive vehicles fare slightly better, they still suffer. The key issue is that the handbrake warning light on the dashboard won't turn off, making the car consume more fuel when driven, and the tires may leave black skid marks on the ground. It's advisable to develop the habit of glancing at the dashboard before starting—it's safer and saves money.
