What Are the Reasons for a Car Not Starting and Brakes Not Working?

The reasons for a car not starting and brakes not working are: 1. The car's steering wheel is locked; 2. The car battery is dead. The function of the brakes is to reduce speed or bring the vehicle to a stop. Their working principle involves using the friction between the brake pads and brake drum, as well as between the tires and the ground, to convert the kinetic energy of the moving vehicle into heat energy through friction, thereby slowing down or stopping the vehicle. The reasons for brake failure are: 1. Impurities in the brake master cylinder or poor sealing; 2. Failure of the vacuum booster pump; 3. Dirty brake fluid; 4. Leakage in the brake master cylinder or wheel cylinder; 5. Air leakage in the air reservoir or pipeline connections; 6. Severe overloading; 7. Carbonization of the brake drum; 8. Lack of brake fluid in the brake master cylinder; 9. Wear of the brake master cylinder piston.
Last time I encountered this issue while driving—the engine wouldn't start, and the brakes were as hard as a rock, which was really scary. After checking, it turned out the battery was drained. Without the engine running, the vacuum booster pump doesn't work, so the brakes lose power assistance and naturally become hard to press. It could also be caused by a starter motor failure or fuel line blockage preventing ignition. Safety first—never force the brakes, as it can damage the system. Try jump-starting first; if that doesn’t work, call a tow truck immediately for repairs. Regularly check the battery life and charging system during maintenance, especially in cold winters or if the car sits idle for long periods, to avoid breakdowns. These small details can prevent most problems.
