What Causes Brake Noise in Volvo Cars?
2 Answers
Volvo brake noise may be caused by the following reasons: Break-in period for new cars: The break-in of brake pads is an important part. It usually takes a few hundred kilometers of driving before the brakes feel more comfortable. Newly replaced brake pads also need a break-in period to better integrate with the old rotors. Initially, the brake pads may feel very hard, and it typically takes a few hundred kilometers of driving for them to feel better. Small sand particles in brakes: While driving, very small sand particles may get between the pads and rotors, sometimes causing noise due to friction. This usually does not require repair; driving for a while can help the particles fall out. Brake damage: Missing or damaged fixing screws on the brake rotors can also cause brake noise. If there is a fault in the brake system, inspection and repair are necessary.
Last time I drove my Volvo, I suddenly heard a sharp squealing sound when braking, which felt like metal scraping and was quite unpleasant. I immediately became concerned about safety. Common causes include severely worn brake pads, hard spots or impurities on the pads, or uneven surfaces causing friction noise. It could also be due to rust on the brake discs, especially after rainy or humid weather, but this type of noise might disappear after driving for a while. If the brake pads were recently replaced, slight noise during the first few hundred kilometers of the break-in period is normal. However, don’t take it lightly, as unusual noises may indicate reduced braking efficiency, increasing the risk of rear-end collisions. I recommend regular inspections of the braking system, such as having it professionally checked every six months or every 10,000 kilometers to ensure everything is functioning properly. Regularly cleaning the tires and brake areas can also help reduce dust buildup.
