The reasons for no braking when pressing the air brake hard are as follows: 1. Lack of brake fluid: Leakage in the brake wheel cylinder, pipelines, and joints, potential damage to the master cylinder or wheel cylinder. 2. Presence of air in the brake system. 3. Excessive gap between the friction pads and the brake drum. 4. Overheating of the brake disc. Precautions for air pressure are as follows: 1. After starting the vehicle, the onboard air pump must be used. 2. Do not blindly choose to use an inflator pump; replace it immediately if there are issues, and check the tire pressure immediately if abnormal. 3. Avoid prolonged use of the inflator pump to prevent overheating and damage.
