Western Star 4900: Brakes

Affects Western Star 4900 · 2011–2019 — about 339 vehicles.

The hazard

Certain vehicles built with front disc brakes and a Lomax hood may not have enough clearance between the hood and the front brake hose. This could cause chafing of the brake hose, which could lead to an air leak resulting in reduced brake effectiveness and increasing the risk of a crash causing injury and/or property damage. Correction: Authorized dealers will replace the front brake hose. Note: A leaking front brake hose may not be detectable during a routine pre-trip inspection.
