NHTSA Complaint #10239752 — 2004 NATIONAL RV SEABREEZE

COMPLETE LOSS OF BRAKING WHILE DRIVING 2004 DOLPHIN MOTORHOME BUILD ON WORKHORSE W22 CHASSIS. MILEAGE IS APPROXIMATELY 34700. HAD TO USE GEARING AND EMERGENCY BRAKE TO CONTROL MOTORHOME. AFTER PARKING INSPECTED MASTER CYLINDER FOR FLUID AND FOUND BOTH RESERVOIRS FULL. COULD SMELL HOT BRAKES O REAR OF COACH. AFTER COOLING OVERNIGHT BRAKE FUNCTION RETURNED BUT HAD ABS LIGHT. MOTORHOME TAKEN TO LOCAL WORKHORSE DEALER WHO CONFIRMED BRAKE BINDING ON REAR AXLE FOR BOTH CALIPERS. THERE IS A RECALL FOR BOSCH SLIDE PIN CALIPERS BUT NOT CURRENTLY FOR MY VIN NUMBER 43382489 BUT THE DESCRIPTION OF THE RECALL IS IDENTICAL TO MY PROBLEM. I HAVE WRITTEN WORKHORSE ABOUT THIS PROBLEM AND AM AWAITING A REPLY. SINCE THE BOSCH CALIPERS ARE THE SAME PART NUMBER FOR ALL FOUR WHEELS I BELIEVE THE RECALL SHOULD BE EXPANDED. THERE ARE SEVERAL BLOGS CONCERNING THIS PROBLEM INCLUDING A2006 MODEL W22. LOCAL WORKHORSE DEALER RECOMMENDED REPLACING ALL FOUR CALIPERS WHICH IS BEING DONE BEFORE I WILL DRIVE UNIT AGAIN. NO DOUBT THE PROBLEM HAS NOT BEEN CORRECTED FOR MANY MORE W22 CHSSIS VIN NUMBERS AND SHOULD BE FOR SAFETY REASONS. THESE BRAKES ARE HYDRAULIC WITH HYDROBOOST. MOTORHOME IS A DOLPHIN LX 6355. *TR
