What is the reason for the hard brake pedal that cannot be pressed down in a car with one-button start?
2 Answers
Car with one-button start brake pedal is hard to press down due to the disappearance of vacuum in the booster pump or booster pump failure. The following are specific explanations for the above issues: Disappearance of vacuum in the booster pump: After turning off the engine, the owner stepped on the brake several times, causing the vacuum in the brake booster pump to disappear. Without the assistance of the booster, it becomes difficult to press the brake pedal. Moreover, the booster pump does not work when the engine is off. The owner only needs to try restarting the engine and press the brake pedal firmly. After starting, it will return to normal. Booster pump failure: The vehicle's brake booster pump has air leakage or component failure. The car's brake pedal is located under the steering wheel. Pressing the brake pedal causes the brake lever to be pressurized and transmitted to the brake shoes on the brake drum, clamping the brake disc, thereby slowing down or stopping the car.
I once encountered a situation where the one-push start brake was hard and couldn't be pressed while driving, which really gave me a scare. The reason might be a malfunctioning vacuum booster pump, which is responsible for providing vacuum assistance when the engine is not running. If it happens after restarting the engine, the lack of vacuum could be due to the engine not operating. It could also be caused by an air leak in the brake system or a blocked vacuum hose. I first tried checking the vacuum hose for any cracks, then gently pressed the brake a few times to feel for any air leakage. In such situations, never force the car to move; instead, pull over immediately and turn on the hazard lights. For regular maintenance, I make sure to periodically inspect the braking system and replace any aging components to avoid safety hazards. Small vehicle issues should be addressed promptly, or they might escalate into major repairs, costing both money and time. Remember, safe driving starts with attention to detail.
