Mercedes-Benz has issued a recall for certain vehicles due to the absence of a system that can detect brake wear, Kelley Blue Book reports.
The recall applies to certain 2019-2020 Mercedes-Benz A-Class, including AMG models; 2020 Mercedes-Benz CLA, including AMG models; 2020 Mercedes-Benz GLB; and 2021 Mercedes-Benz GLA vehicles.
According to the automaker, the vehicles may lack an inspection gauge that can check wear inflicted on the rear axle brake pads. The owner’s manual does not include any information on how to inspect rear brake pads, either.
In spite of this, the vehicles come with a system that can detect if the front brake pads need to be replaced, which Mercedes said usually wears out sooner than the rear. When vehicles with worn front brake pads are brought in to a dealer, they always check the rear, which the company believes should help catch any potential issues.
Though internal tests from Mercedes suggest that front brake pads alone can safely stop a vehicle, they admit that increased wear on the rear brake pads gone unchecked could increase the likelihood of an accident.
To remedy the issue, dealers will add inspection gauges to the rear brakes and information on how to use it in the owner’s manual.
