What Causes the Brake Noise When Driving a Mercedes-Benz GLC?
2 Answers
Mercedes-Benz GLC may produce brake noise during driving due to worn brake pads that need replacement or repair, road bumps, or foreign objects lodged in the brake pads. Reasons for Brake Pad Wear: Frequent braking during turns causes uneven force distribution on the left and right wheels, leading to wear. One side of the brake disc may become deformed. The brake caliper pistons do not retract uniformly. Significant differences in the length of left and right brake fluid lines. Inconsistent braking timing between the left and right brakes. Issues with the ABS control strategy result in unequal pipeline pressure, causing uneven wear. Reasons for Foreign Objects in Brake Pads: Driving on unclean road sections.
The abnormal noise when braking a Mercedes-Benz GLC while driving may involve multiple factors. I've encountered many similar cases, with common causes being dust or small stones adhering to the brake pad surface, creating a screeching sound when rubbing against the brake disc. Rust on brake discs after humid weather can also produce abnormal noises upon initial startup, which usually disappear after a few braking applications to wear it off. Mercedes-Benz models sometimes use high-performance brake pads that are harder in material and prone to noise. Loose installation or component looseness may also cause vibration-induced abnormal noises. If the abnormal noise persists, it might indicate severely worn brake pads needing replacement or grooved/deformed brake discs. For safety considerations, don't delay - early inspection and handling at an authorized service center can prevent accidents. Maintaining clean wheel hubs during daily driving to reduce impurity accumulation helps avoid such issues.
