Service bulletin WQQ-52R

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Unevenness of the backing plate surfaces may affect the concentricity (roundness) of the hub / bearing after torqued during assembly and over time, cause the howling -type sound to develop. Production changes for the backing plates have been implemented to optimize their mounting surface quality.

This will prevent the pad from dragging due to corrosion buildup which may result in uneven or premature wear of the replacement brake pads.
