What is the reason for the noise from the left front wheel of the Mercedes-Benz GLB?

[OIsabella]

Mercedes-Benz GLB left front wheel noise reasons are as follows: Severely worn brake pads: Normal brake pad thickness is around 10mm. When the brake pads wear down to below 6mm, the vehicle will experience tire noise and weak braking symptoms. In this case, the brake pads need to be replaced. Foreign objects on the brake disc: If sand, mud, or other foreign objects adhere to the brake disc, friction between them can also cause noise. In this situation, simply cleaning them will suffice. Deformed left front wheel hub: If the car frequently travels on bumpy roads or high-speed sections with potholes, the significant impact can cause the front wheel to deform, leading to noise. For safety reasons, it's best to replace the wheel hub in this case.
