20150204SERVICE BRAKES
WHILE DRIVING HOME ABOUT 10 PM ON IDAHO 200 THE ABS LIGHT CAME ON, ABOUT 1 MINUTE LATER THE HAND BRAKE LIGHT CAME ON AND STARTED TO BRAKE THE CAR, AFTER A FEW SECONDS THE LIGHT WENT OF AND THE CAR STARTED TO ACCELERATE, FEW SECONDS LATER THE BRAKE LIGHT CAME BACK ON AND THE CAR STARTED TO BRAKE THEN LET OFF. THIS CONTINUED FOR ABOUT 7 TO 10 MINUTES. FINALLY THE ABS LIGHT STAYED ON BUT THE BRAKE LIGHT WENT OFF AND STAYED OFF. THE ROAD (200) AT THAT TIME IS VERY LIGHTLY TRAVELED AND WE WANTED TO GET HOME AND NOT GET STRANDED AT THAT TIME OF THE NIGHT IN A NO CELLPHONE AREA. IF I WERE DRIVING ON I90 AT 70MPH IN HEAVY TRAFFIC THERE WAS A GREAT CHANCE THERE WOULD BE A REAR END COLLISION, FOR WHEN THE HAND BRAKE IS ACTIVATED THERE IS NO BRAKE LIGHTS TO WARN DRIVERS FOLLOWING ME THAT THE CAR AHEAD OF THEM IS STOPPING. *TR
