CURRENTLY OWN 1986 BUICK ESTATE EQUIPPED WITH "POWER MASTER" BRAKE UNIT. THIS IS THE ORIGINAL FACTORY BRAKE UNIT FOR THIS AUTOMOBILE. THE PRESSURE SWITCH DEVELOPED A CRACK, ALLOWING THE BRAKE FLUID TO BE PUMPED OUT. MY FATHER WAS DRIVING THE VEHICLE AT THE TIME, AND MANAGED TO GET THE CAR STOPPED AND OFF THE ROAD WITHOUT CRASHING. NEVERTHELESS, THE RESULTS COULD HAVE BEEN MUCH DIFFERENT. WHAT'S MORE, I KNOW NOW THAT GM HAS LONG BEEN AWARE OF THIS DEFECT. SINCE THIS OCCURED, I HAVE LEARNED THAT GM WAS AWARE OF THIS PROBLEM FOR QUITE SOME TIME, AND ISSUED A RECALL FOR THIS PARTICULAR PART (PRESSURE SWICTH) AS WELL AS FOR THE DIVIDER VALVE. UPON CONTACTING THE LOCAL GM DEALER (DALLAS AUTOMOTIVE GROUP, JACKSON, OH.) I WAS INFORMADE THAT MY VEHICLE WAS NOT COVERED BY THIS RECALL. IN FACT, I WAS TOLD THAT IT ONLY APPLIED TO 2 VIN! FINDING IT HARD TO BELIEVE THAT A RECALL WAS ISSUED, BUT FOR ONLY 2 VEHICLES, I CONTACTED GM CUSTOMER ASSISTANCE. I TALKED WITH GREG MARTIN, CUSTOMER RELA
