2004 Workhorse W20 recalls
Recall 09V-110: Service Brakes, Hydraulic
Problem: Navistar is recalling certain model year my 2001-2008 workhorse w20, w21 and w22 chassis and certain model year 2009 through 2011 monaco rv admiral, arista, monarch, and riptide recreational 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.
Risk: 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.
Fix: Workhorse dealers will replace all four bosch brake caliper assemblies free of charge. The safety recall began on september 16, 2010. Owners may contact workhorse at 1-877-246-7731.
Recall 06V-225: Engine and Engine Cooling

If the damper becomes loose, fuel could be pumped by the fuel pump into the under hood area.
Risk: In the presence of an ignition source, a fire could result.
Fix: Dealers will replace the fuel rail pulse damper retainer clips on these engines free of charge. The recall began on september 1, 2006. Owners may contact workhorse at 877-294-6773.
