Official summary

Freightliner Service Bulletin for Meritor Steer Axle Drum Brake Squeal. Some Cascadia and New Cascadia vehicles equipped with Meritor steer axle drum brakes with a front axle rating less than 13,300 lb (6038 kg) have experienced brake squealing noise when the service brakes are applied at lower speeds. NOTE: This is a nuisance noise issue and not a failure. The solution given in this service bulletin may fix this issue.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
