The contact owns a 2004 Workhorse W22 RV. The contact stated while driving approximately 60 MPH, the brakes heated up and seized. The contact stated that the ABS warning light was illuminated. The contact pulled over and smelled a burning odor. The contact stated that he waited for over one hour for the brakes to cool and then he continued driving to his destination. The contact stated that the failure became constant and he no longer took the RV on long trips. The contact had taken the RV to an independent mechanic where it was diagnosed and determined that the calipers, pistons, sensors, and rotors needed to be replaced. The RV had been repaired; however, the failure reoccurred. The manufacturer had not been informed of the failure. The failure mileage was approximately 60,000.

Apr 3, 2009

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.

Consequence & remedy

Consequence: 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.

Remedy: 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.
