Why Does the Brake Make Abnormal Noises When Turning?
2 Answers
Reasons for abnormal brake noises when turning: poor quality brake pads, foreign objects entering the brake disc, severe wear of the brake disc, severe wear of the brake pads, rust on the brake disc, etc. The following is a detailed analysis: Poor quality brake pads: If the brake pads installed are not provided by a reputable manufacturer or are of inferior quality purchased by the owner themselves, the overly hard material can cause a squeaking sound when braking and also damage the brake disc. Therefore, it is advisable to replace the brake pads with genuine ones at an authorized 4S shop. Foreign objects entering the brake disc: When driving on complex road conditions, the wheels can easily fling stones or other foreign objects. Unlike drum brakes, disc brakes can trap stones between the brake pads and the brake disc, causing abnormal noises when braking. Severe wear of the brake disc: Sometimes, the brake disc can be directly scratched by foreign objects or hit by other objects, leaving pits on the surface. When the brake pads rub against an uneven brake disc, it can also produce squeaking noises. Severe wear of the brake pads: After driving for a certain period, the brake pads will thin out due to prolonged friction. Overly thin brake pads not only reduce braking effectiveness but also cause abnormal noises due to the hardening of the material. Rust on the brake disc: Years of exposure to wind and rain can cause the brake disc to rust. However, this situation is not a cause for concern, as stepping on the brakes a few times will wear off the rust layer on the brake disc.
As a seasoned driver with over a decade of experience, I've encountered many instances of brake noise during turns. The most common cause is worn-out brake pads, where the metal backing plate directly rubs against the rotor, producing a sharp squealing sound. Some new cars may also squeak after just a few thousand kilometers, often due to improperly bedded-in brake rotors. Road debris like sand or metal shavings trapped between the pads can create abnormal noises when braking during turns. Suspension system issues shouldn't be overlooked either - worn or loose tie rod ends, for example, will produce noticeable clunking sounds during braking. In my last car, aged suspension bushings caused distinct knocking noises whenever I braked while turning. Warped or uneven brake rotors will also cause vibration and noise during slightly turning brakes. My advice is to start with simple checks: inspect pad thickness and clean the braking system of foreign objects. If the problem persists, move on to examining steering and suspension components - safety always comes first.
