DRIVING TO WORKHORSE SERVICE CENTER (JIM PRICE CHEVY TRUCK CENTER, CHARLOTTESVILLE VA) FOR A DIFFERENT MATTER THE DASH WARNING LIGHTS STARTED BLINKING FOR BRAKES, ABS, ATC AND PARKING BRAKE. SERVICE CENTER HOOKED UP COMPUTER AND DETERMINED THAT THE MERITOR/WABCO HYDRAULIC COMPACT UNIT (HCU) WHICH IS THE MAJOR PART OF THE HYDRAULIC POWER BRAKE (HPB) SYSTEM MALFUNCTIONED. I LEARNED THAT THESE UNITS ARE ON MANY INTERNATIONAL BRAND SCHOOL BUSES AS WELL AS MY WORKHORSE UFO CHASSIS RV AND OTHER VEHICLES AND THAT THE HCU IS FAILING ON A REGULAR BASIS ON THESE AND OTHER VEHICLES AND THAT MERITOR/WABCO HAS REDESIGNED THE INTERNALS AND EXTENDED THE WARRANTY ON SAME. WORKHORSE ARRANGED TO HAVE A REDESIGNED UNIT FROM MERITOR/WABCO OVERNIGHTED AND INSTALLED THE NEXT DAY. HOWEVER, SINCE IT IS A CRITICAL BRAKE PART WHY HAS THERE NOT BEEN A RECALL BY MERITOR/WABCO? OUR SCHOOL CHILDREN ARE AT RISK! PLEASE INVESTIGATE IMMEDIATELY. THE NEWSPAPERS WOULD LOVE TO GET THIS FIRST. PLEASE GET OUT IN FRONT OF THIS QUICKLY.
