Service bulletin S26DZ
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.

NHTSA's summary
The mechanical brake switch & bracket design has a potential for cumulative at-limit stack up clearances to exceed the limitations of the mechanical switch. As a result, a preventative maintenance adjustment procedure is necessary and, at times, settings can be difficult to achieve.
