THREE BRAKE LINES RUPTURED SIMULTANEOUSLY CAUSING AN INABILITY TO STOP THE VEHICLE. THE CAUSE OF FAILURE WAS RELATED TO AN EXTENSIVE AMOUNT OF CORROSION ON ALL OF THE BRAKE LINES ON THE VEHICLE. COMPLETE REPLACE IS NECESSARY. THERE IS A REGIONAL RECALL ON THIS EXACT ISSUE BUT DOES NOT INCLUDE MY STATE. THERE ARE CONSIDERABLE REPORTS OF THIS FAILURE ACROSS THE COUNTRY BUT GM AND EVEN WORSE NHTSA FAILS TO FORCE A NATIONWIDE RECALL OF THIS POTENTIALITY DEADLY FAILURE. A SIMPLE SEARCH OF THE INTERNET WILL PROVE THIS DEFECT IS NOT CONSTRAINED TO ONLY THE RUST BELT STATES. MY '66 CHEVY STILL HAS THE ORIGINAL BRAKE LINES WITH NO SIGNS OF DEGRADATION HOWEVER MY '02 GMC REQUIRES THE REPLACEMENT OF ALL METAL LINES ON THE VEHICLE. THE EXISTENCE OF A CURRENT REGIONAL RECALL PROVES THAT GM ADMITS TO THE PROBLEM! THIS FAILURE NEEDS TO BE CORRECTED NATIONWIDE. *LN
