Why is the car's brake pedal sometimes too hard to press?
2 Answers
The car's brake pedal sometimes being too hard to press is caused by a failure of the brake booster pump, and it is recommended to have it inspected and repaired. Below is an introduction to the handbrake: 1. Introduction: The professional term for the handbrake is auxiliary brake, which operates on a different principle from the main brake. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. 2. Configuration: The handbrake is used in conjunction with a return spring. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. With prolonged use, the spring may also deform. 3. Principle: For small cars, the handbrake is sometimes located behind the transmission, connected to the driveshaft with a brake disc, similar to a disc brake. The pulling force is transmitted via a steel cable to achieve parking braking.
I found that my car's brakes sometimes suddenly become hard, feeling like stepping on a rock, which is really scary. This is usually due to a problem with the brake booster system. The booster relies on the engine's vacuum to assist in braking. If there's a leak in the vacuum pump, aging or cracked hoses, or internal damage to the booster, the assistance is lost, and the pedal naturally becomes stiff. I once experienced this on the highway and almost had an accident, so now I always check the vacuum hoses and booster pump regularly to ensure there are no cracks or looseness. When driving, pay attention to the feel—if there's a hissing sound or pedal rebound when braking, take it to a professional shop immediately. Don't wait for a small issue to become a big one. Safety first—addressing problems early is more reassuring and can save on repair costs. A failing brake system is no joke.
