I CAME TO AN INTERSECTION AND STOPPED, THEN TOOK MY FOOT OFF THE BRAKE BEFORE NOTICING THAT THE LIGHT WAS STILL RED. THE OTHER VEHICLE WAS ROUGHLY 30 FEET AWAY WHEN I PUSHED ON THE BRAKES. I SHOULD HAVE EASILY BEEN ABLE TO STOP. BRAKES DID NOT ENGAGE AND I HAD BEEN PUSHING THEM SO HARD AND FOR SO LONG THAT I FRACTURED MY ANKLE. THERE WERE NOT EVEN SKID MARKS AT THE ACCIDENT SCENE. MY CAR HAD FRONT END FRAME DAMAGE FROM THE ACCIDENT (TOTALED), AND THE AIRBAGS NEVER DEPLOYED. ADDITIONALLY, IN THE PAST I HAD NOTICED THE RPMS RISING FOR NO REASON WHILE CAR WAS IDLING, AND THE ACCELERATION ISSUE, WHERE THE VEHICLE SEEMED TO ?HANG? BETWEEN SPEEDS OF ABOUT 35 AND 40 AND 60 AND 65MPH. THE RPMS I ONLY NOTICED ONCE-SO I DID NOT REPORT IT, AND THE ?HANGING? WAS MY OWN IGNORANCE (I HAVEN?T HAD A 4 CYLINDER IN A LONG TIME AND THIS WAS MY FIRST?AND PROBABLY LAST?TOYOTA). I ALSO HAD PRIOR BRAKING CONCERNS-- ABS ONLY MADE A NOISE (DID NOT VIBRATE AGAINST PEDAL--AGAIN, MY IGNORANCE OF HOW THIS VEHICLE WAS SUPPOSED TO RESPOND) AND IT WAS A VERY ICY WINTER, SO I ASSUMED THAT I HAD BEEN TRYING TO STOP ON ICE. THE BRAKES BEHAVED FINE IF I PHYSICALLY PUMPED THEM, BUT SUDDEN STOPS COULD NOT BE MADE. *TR
