What Are the Consequences of Forgetting to Engage the Handbrake When Parking an Automatic Transmission Car?

[OSebastian]

Forgetting to engage the handbrake when parking an automatic transmission car can damage the transmission, making gear shifting more difficult during subsequent driving. The hazards of driving without releasing the handbrake are as follows: 1. Driving with the handbrake engaged for an extended period directly wears down the handbrake mechanism. Additionally, the pressure on the handbrake is inconsistent during driving, fluctuating with speed, speed bumps, or even collisions with obstacles. This means the handbrake undergoes continuous wear and tear of varying degrees throughout the journey. 2. In severe cases, it can lead to brake failure, smoke, or even fire. Prolonged driving with the handbrake engaged may cause the brake caliper to seize, brake fluid to leak, and the brake fluid temperature to rise excessively, resulting in a complete loss of braking function. This is extremely dangerous while driving. If a strong burning smell or smoke from the rear of the car is noticed, the driver should immediately reduce speed, apply the brakes, and release the handbrake.
