Open the full vehicle complaint log (all categories)NOTICED BRAKE FLUID ON FLOOR OF MY GARAGE. FOUND THAT THE BRAKE LINE TO THE REAR BRAKES WAS RUSTED AND LEAKING. GM DEALER SAID IT WAS OUT OF WARRANTY SO I PAID A LOCAL GARAGE TO INSTALL NEW BRAKE LINE. IT HAS FAILED AGAIN, 98,000, WHILE I WAS DRIVING. LOST BRAKING ABILITY. I FIND THAT GM WILL SELL ME A SET OF BRAKE LINES FOR $500 AND I CAN HAVE THEM INSTALLED ANYWHERE I WANT TO. CONSIDERING THE CURRENT GM SITUATION WITH THE IGNITION SWITCH I THINK THEY SHOULD BE MADE TO RECALL ALL EFFECTED VEHICLES AND FIX THEIR RUSTING BRAKE LINES. *TR
