What happens if the parking brake is not released?

[McMary]

If the parking brake is not released, it will cause the brake discs (drums) of the two rear wheels to overheat and even turn red after a long distance, which only accelerates the wear of the brake pads. The degree of wear on the brake pads can be determined by the effectiveness of the braking or by observing the position of the brake handle—whether it needs to be pulled tighter to be effective. Precautions for using the parking brake are: 1. Pull the parking brake until the rear wheels lock, then lift it 1 to 2 notches further to ensure the car does not roll; 2. When parking on a slope, use the parking brake to secure the car, then place bricks or other objects under the tires. Once the wheels are firmly fixed, release the parking brake to transfer the load to all four wheels, then pull the parking brake again so that both the wheels and the parking brake share the load.
