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. Updated 10/20/10 *bf updated ivoq 10/26/10*jb
