Should the parking brake be applied later on an uphill slope than on a flat road?

On an uphill slope, the parking brake should be applied later than on a flat road. Here are the specific reasons why the parking brake should be applied later on an uphill slope: 1. Preventing rollback: When stopping a car on an uphill slope, first press the brake pedal. The hill start assist system recognizes the braking action and maintains the braking state for about 2 seconds after releasing the brake pedal. During this time, you can move your foot to the accelerator pedal to prevent possible rollback. Pressing the accelerator to drive improves the safety of starting on a slope. 2. No rollback tendency: When the slope is relatively small and there is no tendency for the car to roll back, the hill start assist system does not engage. Most cars are equipped with a Hydraulic Brake Assist system (HBA) and a Hill Hold Control system (HHC). The HBA can automatically recognize when the vehicle needs emergency braking and can reduce the required brake pedal force, making it both convenient and flexible.
