What Are the Causes of Brake System Failure?
4 Answers
Introduction to the causes of brake system failure: Severe wear of brake pads: Brake pads are divided into two types: those with sensor lines and those without. For those with sensor lines, when the brake pads wear to the limit position, the sensor line will automatically connect the circuit, triggering the fault light. Low brake fluid level: Brake fluid plays a crucial role in the vehicle's braking system. When the driver presses the brake pedal, the force applied is transmitted by the piston in the master cylinder through the brake fluid to the wheel cylinders located at each wheel, causing the brake pads to contact the wheels and stop the vehicle. A lack of brake fluid is often accompanied by significantly reduced braking force, and in severe cases, a complete loss of braking power. This issue can be resolved by promptly replenishing the brake fluid. Brake system oil leakage or false alarm: If the brake system warning light comes on while driving, the driver should remain calm, slow down as much as possible, pull over promptly, and then proceed to diagnose the cause of the fault.
I've worked in auto repair shops for many years and frequently deal with brake failures. The most common issue is brake pads wearing too thin—after prolonged use, they get as smooth as the soles of shoes, losing their stopping power when pressed. Another problem is warped or rusted brake rotors; driving through puddles without promptly drying them can cause brake shudder or noise. Additionally, oil leaks or blockages in the brake lines can bring the entire system to a halt. I recommend car owners check their brake pad thickness every few thousand kilometers and seek repairs immediately if they notice soft braking or unusual noises. This isn’t a minor issue—failing to stop at high speeds is extremely dangerous, so don’t cut corners to save money. Timely maintenance is crucial for safety. Safety comes first—I’ve seen too many cases where delays led to accidents.
I've been driving for over ten years, and personally, I feel that most brake problems are related to brake fluid. If the fluid level is too low or the fluid has aged, allowing air to enter the system, the pedal feels soft and spongy, like stepping on cotton. My car had this issue last time, and it turned out there was a slight leak in the brake line. It was fixed after replacing the fluid. During regular maintenance, it's best to check the fluid level every six months and top it up with fresh fluid if necessary. Additionally, a faulty wheel cylinder or master cylinder can cause similar symptoms, as the entire system loses pressure and fails. Remember to avoid contaminating the fluid, as it can significantly increase braking distance, which is quite dangerous. Taking care of these details can help reduce safety concerns.
I'm a car enthusiast who loves studying new technologies. Sometimes, brake failures are caused by electronic system issues. For example, if the ABS sensor is dirty or damaged, the computer can't control the brakes properly, and the warning light will come on, indicating the need for inspection. Additionally, problems with the controller or short circuits in the wiring can cause sudden brake failure. With modern cars, you need to be careful in this regard—avoid random modifications, as they can easily interfere with the original system. Checking fault codes promptly can save you from major trouble.
