Is it harmful to drive 20 kilometers with the handbrake on?
3 Answers
Driving 20 kilometers with the handbrake engaged requires an inspection. If the handbrake is not released while driving, the most immediate effects include accelerated wear of the brake discs, hardening of the brake pads due to overheating, and elongation of the handbrake cable. This can increase vehicle wear and fuel consumption, and in severe cases, may lead to accidents. The following are the consequences of driving with the handbrake on: 1. High brake disc temperature: The rear brake discs may overheat, emitting a burnt smell, and in severe cases, turn red, leading to severe thermal fade and reduced braking performance. 2. Brake pad wear: This causes wear on the brake pads, shortening their lifespan. 3. Increased fuel consumption: Fuel consumption significantly rises, with reduced acceleration and a dragging sensation when releasing the throttle.
Oh, I've encountered this situation several times. Driving with the handbrake on, especially for over 20 kilometers, is really damaging to the car. The brake pads and discs keep rubbing against each other, causing the temperature to skyrocket. At best, it accelerates wear and significantly reduces lifespan; at worst, it can cause disc deformation or burning, leading to strange noises or brake failure. After driving like this, I noticed smoke coming from under the car, which scared me into stopping to check. The brake discs were so hot you could fry an egg on them, and the repairs later cost me several hundred dollars. Fortunately, nothing major happened, but driving safety is not something to take lightly. Next time before starting the car, make sure the handbrake is released—developing this habit will prevent forgetfulness. Additionally, driving like this frequently will also cause fuel consumption to soar, wasting money on gas.
As a seasoned driver with years of experience, I think this issue is somewhat serious but not that terrifying. Driving 20 kilometers with the handbrake engaged causes continuous friction between brake components like pads and discs, leading to overheating or even damage. If you didn't smell smoke or hear unusual noises while driving, and the car still moves, the wear must be significant. I suggest parking the car afterward and checking the temperature of the brake components. If they're cool, it might still be usable, but get it inspected ASAP. Prevention involves developing a habit of testing the brakes before starting the car—don't rush to hit the gas. This problem is common among beginners or those in a hurry; more practice can help avoid it. One occasional slip-up might be fine, but frequent mistakes will accelerate component wear and increase repair costs.
