Summary

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.

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.
