NEWMAR issued a recall on multiple vehicle models

On certain vehicles, a quick release valve (QRV) contains a rubber diaphragm that may delaminate and cause leakage, a restriction, or blockage of the airflow, thereby affecting pressure delivery and release to the foundation brakes. Air trapped in the spring brake chambers could cause the parking brakes to apply slower than expected, which could allow the vehicle to roll away causing a risk or property damage, personal injury or death. Correction: Dealers will inspect and replace defective quick release valves.
