Service bulletin MC340320

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.

MC32001152018-12-10. Service bulletin. When the brake system is filled with fluid for the first time in the assembly plant, a float is installed in the fluid reservoir of the handbrake fitting (see Figures 1 and 2). This float is required only for the initial, vacuum-assisted filling of the system. As long as the float remains in the reservoir it is subsequently not possible to obtain a clear reading of the brake-fluid level. In order to make it easier for the fluid level to be read correctly, the float has to be removed.
