What Causes Brake Disc Noise While Driving?
1 Answers
The causes of brake disc noise while driving include normal ABS activation, rust on brake pads/discs, excessive wear of brake discs and pads, and installation issues. Below are detailed explanations for each cause: The ABS operation process is actually a cycle of locking, releasing, locking, and releasing, keeping the vehicle in a state of near-lock rolling. Therefore, when ABS is activated by sudden braking, noise is normal, and pressing the brake pedal fully can resolve it. After prolonged parking, especially in humid weather or after rain, some rust or dirt may form on the brake discs or pads. Driving for a while can solve this, or applying butter or specialized lubricant at the connection between the brake pads and calipers may help. Both brake discs and pads are high-wear components. Every time you brake, these two parts experience friction, leading to wear over time. Excessive wear naturally causes noise, so regular inspection and replacement are necessary. Typically, brake pads should be replaced every 60,000-80,000 km, while brake discs last 100,000-120,000 km. Incorrect installation or mismatched models of brake pads can also cause noise. Reinstalling the brake pads may resolve this. Owners should have brake pads installed at professional auto repair shops, especially those who have had them replaced at roadside stalls, as extra caution is needed.
