What Causes the Abnormal Noise When the Audi Q5 is Stationary and Braking?
1 Answers
It is normal for a new car's brakes to make abnormal noises, which usually disappear after a running-in period of more than 200 kilometers. If it's not a new car, other causes should be considered. Replacement of new parts: Replacing new friction pads or new brake discs may cause abnormal noises temporarily, as the new brake discs cannot immediately achieve good running-in with the friction pads. Hard substances entering: Sometimes, hard substances like sand or stones entering the gap between the brake disc and brake pads can also cause abnormal noises, typically occurring during the initial driving phase. Such noises can generally be ignored. After wading through water or driving on muddy off-road conditions, hard sand or stones may enter the gaps of the braking mechanism, causing jamming during braking system operation, leading to abnormal noises when they reach the gaps of the brake disc. Poor fixation: Poor fixation of the brake caliper or brake disc can also be a cause of abnormal braking noises and may lead to uneven brake wear. Excessive wear: Excessive wear of the brake disc or cracks in the brake pads, even if not excessively worn, can also cause abnormal braking noises. Solution: If the cause cannot be determined, it is recommended to have it checked promptly.
