What are the hazards of not releasing the handbrake in an automatic transmission car?
3 Answers
Not releasing the handbrake in an automatic transmission car can cause the following hazards: accelerated wear of the brake discs, and the brake pads may harden due to overheating, leading to reduced handbrake performance and elongation of the handbrake cable. The functions of the handbrake are: 1. When parking, pulling the handbrake keeps the car stationary and prevents it from rolling downhill; 2. During turns while driving, applying the handbrake can create a drifting effect; 3. In emergency situations, the handbrake can be used as a brake. The handbrake, also known as an auxiliary brake, is a crucial component of the vehicle's braking system. Proper use of the handbrake can effectively prevent the car from rolling and reduce the danger of rolling when parked.
Once I was in a hurry and forgot to release the handbrake before driving. After driving for a while, I noticed the car was struggling to move, acceleration was sluggish, and fuel consumption skyrocketed—nearly double the usual amount. When I got out to check, the brake discs were scorching hot with a burning smell. Later at the repair shop, I found the brake pads had worn out and deformed. This causes serious harm: it mainly accelerates early wear of the braking system, leading to overheating, deformation, or even failure of components. It also puts extra stress on the drivetrain, potentially damaging parts like the transmission prematurely. Most critically, it’s a safety hazard—driving with the handbrake on can slow reaction times in emergencies, increasing accident risks. Now I’ve made it a habit to glance at the handbrake warning light on the dashboard before starting, ensuring it’s released before driving. It’s both hassle-free and safer, saving me from unnecessary repair costs.
As a novice driver, I used to make this common mistake of forgetting to release the handbrake before starting, which resulted in the car struggling to accelerate, feeling like it was being dragged, and producing strange noises. The consequences are serious: continuous friction heats up the brake pads, leading to deformation or melting and increasing the risk of failure; the engine bears extra load, consuming more fuel and reducing power efficiency; prolonged neglect can damage transmission components, leading to costly repairs. This is especially risky for automatic transmission cars, as they lack a clutch reminder, making oversight easier. Now, I force myself to check the handbrake position before every departure, and this habit has made driving much safer. Safety first—don’t let small mistakes cause big trouble.
