What are the warning signs of brake failure?
2 Answers
Introduction to the warning signs of brake failure: 1. The brakes feel increasingly soft. Abnormal weakening of braking force can result from three situations. Insufficient oil pressure in the wheel cylinder or master cylinder, or possible oil leakage. 2. The brake pedal fails to return fully. If the brake does not return, check whether the brake fluid is insufficient, whether there is oil leakage in the brake wheel cylinder, pipelines, or joints, and whether the master cylinder or wheel cylinder components are damaged. 3. The brakes feel increasingly hard. When pressing the brake pedal, if it feels high and stiff, making starting or driving difficult, it may be due to a faulty one-way valve in the vacuum storage tank of the brake booster system. 4. Trembling when pressing the brake. This is usually caused by uneven surface flatness of the brake disc, especially in older vehicles. The faster the speed, the more intense the vibration when braking. It is recommended to replace the wheel hub brake pads. 5. Uneven braking when pressing the brake. This is mainly caused by uneven force application on the brake pads by the left and right wheel cylinders of the brake system.
Don't ignore those warning signs before brake failure. Having driven for decades, my experience tells me that when the brake pedal becomes too soft or has increased travel distance, that's the first red flag. Strange noises during braking, like metal grinding or hissing sounds, indicate worn brake pads. Slower deceleration, especially on rainy days or slopes, suggests reduced braking efficiency. If the brake warning light comes on or you smell burning, that signals hydraulic system leakage. I've encountered this situation before - fortunately, I got to the repair shop in time to replace components, otherwise it could have been disastrous on the highway. Pay attention to these changes during daily driving and develop the habit of listening to your car's sounds - it could save your life in critical moments. Regular maintenance checks on brake fluid and pad thickness can also prevent problems.
