NHTSA recall 09V217000

What's wrong: Affects vehicles equipped with axles that include bosch zops or zoht pin slide hydraulic disc brakes. When combined with occasional or seasonal vehicle operation may experience calipers sticking in the applied position. This can result in abnormal heat generation at the wheel end causing brake drag. The driver would normally have warning of the brake drag if undetected by the driver.

Why it matters: The driver would normally detect the brake drag but if undetected the temperature increase at the wheel end can eventually lead to soft pedal conditions due to brake fluid boil, and possible extended stopping distance increasing the risk of a crash.

The fix: Dealers will inspect and replace the necessary components free of charge. Workhorse is handling the remedy and owner notification for this campaign please see 09V-110.
