Why Can't the Car Start When the Brake Pedal Can't Be Depressed?

[BeauRose]

The reasons why the car brake can't be depressed and the car can't start: 1. The car's vacuum booster pump is leaking or malfunctioning; 2. There are too many impurities in the brake master cylinder, the seal is not tight, the vacuum booster pump fails, or the brake oil is too dirty; 3. The brake oil mixed and used generates vapor lock after heating, the brake master cylinder or wheel cylinder leaks, or the air tank or pipeline interface leaks; 4. Improper operation causes mechanical failure. Correct braking methods: 1. When driving at low speed and encountering an emergency ahead, you can apply emergency braking by stepping on the brake pedal firmly; 2. When driving under normal road conditions, you can apply gentle braking by releasing the accelerator pedal while depressing the clutch pedal, shifting to a lower gear, and then lifting the clutch pedal after the speed decreases, followed by depressing the brake pedal until the car stops; 3. In situations where long downhill slopes in mountainous areas or continuous braking can easily generate high temperatures, intermittent braking by alternately depressing and releasing the brake pedal can effectively prevent the braking system from overheating.
