What are the reasons why the Baojun 510's brake cannot be pressed and the engine cannot start?

It may be due to issues with the battery or unsuitable engine oil. The following are detailed explanations of the reasons: Check the battery status: In winter, the difficulty in starting a car is mostly caused by a depleted battery or an expired battery lifespan. Avoid continuous ignition to prevent the battery from being completely drained. When the battery is low on power, the starting speed of the car will be weak, and you will only hear a clicking sound. During ignition, the clicking sound will gradually turn into a hissing sound.
I've encountered this situation quite a few times during decades of driving. If the Baojun 510's brakes won't depress and the engine won't start, it's mostly likely a vacuum booster system issue. The brakes rely on engine vacuum to assist pedal pressure - when the engine isn't running, vacuum disappears, making the brake pedal rock-hard. Insufficient battery power is another major cause, especially in cold weather or with aged batteries. Weak electrical current can prevent ignition while adding extra strain. A faulty brake switch can also block ignition since automatic transmission vehicles require brake pedal depression to start. Other minor culprits include blown fuses or poor wiring contacts. My advice: don't force it. First test battery voltage (below 12V is dangerous), then check vacuum hoses for leaks. If unresolved, call professional mechanics to prevent greater damage. Safety always comes first - develop regular vehicle inspection habits to minimize risks.
