Why Does Brake Failure Occur Sometimes?
2 Answers
The causes of brake failure include the following points: 1. Lack of necessary maintenance on the braking system, excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, overly dirty brake fluid or mixing different types of brake fluid leading to vapor lock when heated, leakage in the brake master cylinder or wheel cylinders, and air leaks in the air reservoir or pipe connections. 2. Mechanical failure due to improper operation, such as prolonged downhill driving causing the brake pads to overheat from friction, carbonization of the brake drums, and complete loss of braking function. 3. Severe overloading, which increases the vehicle's inertia under gravitational acceleration, directly leading to brake failure.
One of the most common causes of brake failure is brake fluid leakage or insufficient levels, which prevents the hydraulic system from transmitting adequate pressure. Another factor is severely worn or contaminated brake pads, which reduce friction. In my practical driving experience, I've observed many people neglect regular brake pad replacement, even leading to damage to the brake discs. Additionally, blocked brake lines or air entering the system can cause inconsistent brake feel, affecting responsiveness. Vehicle overheating is also an issue, with frequent hard braking causing heat fade that instantly reduces effectiveness. Finally, faults in the brake system's springs or boosters may also lead to failure. As a professional who frequently deals with such issues, I recommend checking brake fluid levels and brake pad thickness every six months, replacing them promptly to avoid sudden accidents. Moreover, older vehicles are more prone to problems, and regular maintenance can significantly improve safety. Remember, brakes are a matter of life and death and must be taken seriously.
