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 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.
Manufacturer remedy

ON CERTAIN MOTORHOME CHASSIS EQUIPPED WITH BOSCH ZOPS, THE PADS CAN DRAG ON THE ROTOR SURFACE DUE TO THE PIN SLIDE.
Safety risk
A HANG UP OR LOCK UP MAY CAUSE THE CALIPERS TO OVER HEAT AND NOT ALLOW THE DRIVER TO STOP SAFELY. THIS COULD CAUSE OVERHEATING OF THE BRAKE CALIPERS WHICH COULD RESULT IN A VEHICLE FIRE.
Manufacturer remedy
DEALERS WILL INSPECT, REPAIR AND REPLACE ACCORDING TO THE PROCEDURE DEVELOPED BY BOSCH (SEE CAMPAIGN 03E064000). THE RECALL BEGAN ON AUGUST 1, 2004. OWNERS SHOULD CONTACT WORKHORSE AT 1-877-294-6773.
