Sterling 7500: Brakes

Affects Sterling 7500 · 2009–2010 — about 40 vehicles.

The hazard

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 of property damage, personal injury or death. Correction: Dealers will inspect and replace defective quick release valves.
