- The 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.
- The 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.
- The 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.
