2013 Toyota Tundra Brakes Problems

I WAS PULLING INTO MY DRIVEWAY, ABOUT TO PARK. WHEN I BRAKED IT WAS AS IF THE "POWER" IN THE POWER BRAKES HAD FAILED. I HAD TO STOMP ON THE PEDAL. I NEARLY HIT MY HOUSE. THIS WAS ONE WEEK AGO. TODAY, AS I LEFT A PARKING LOT, I NOTICED IT HAPPEN AGAIN: VERY LITTLE STOPPING POWER, BUT NO SOFTNESS IN THE PEDAL. I PLACED THE TRANSMISSION IN PARK AND SAW NO BRAKE FLUID UNDER THE TRUCK. I BEGAN DRIVING SLOWLY AGAIN, AND HAD TO STOMP THE PEDAL TO OBTAIN BRAKING POWER. THE BRAKE LIGHT SUDDENLY CAME ON. A CLICK OR PULSE OCCURED IN THE BRAKES, FELT THROUGH THE PEDAL, AND SUDDENLY THE BRAKES BEGAN FUNCTIONING PROPERLY. THE BRAKE LIGHT REMAINED LIT UNTIL I STOPPED AND RESTARTED THE TRUCK. UPON RESTARTING THE TRUCK, EVERYTHING FUNCTIONED NORMALLY, AND THE BRAKE LIGHT DID NOT LIGHT AGAIN. I WILL NOT DRIVE THE TRUCK UNTIL IT GETS INTO THE DEALER (THEY'RE BOOKED FOR 3 DAYS). THIS IS A SERIOUS SAFETY CONCERN, AND I SEE THAT ANOTHER OWNER HAS REPORTED A SIMILAR PROBLEM. PLEASE INVESTIGATE THIS!

BRAKES DO NOT FUNCTION PROPERLY NOR CONSISTENTLY. I AM HONESTLY CONCERNED (IF NOT AFRAID) ABOUT A SPORADIC NOISE I AM HEARING AND HAVE CONTINUED TO HEAR AND EXPERIENCE SINCE I PURCHASED THIS TRUCK. THE NOISE IS A THUD AND A FEELING AT THE BRAKE PEDAL ALONG WITH A GREATLY INCREASED AMOUNT OF STOPPING DISTANCE NECESSARY TO SUCCESSFULLY BRINGING THE VEHICLE TO A COMPLETE STOP. I HAVE MADE THIS CONDITION KNOWN SINCE MY PURCHASE AND SERVICE DONE WITHIN FLORIDA, AS DURING BREAK IN CERTAIN CONDITIONS WERE APPLICABLE DISGUISING THE CONDITION BUT NEEDLESS TO SAY IT IS A SURE AND CERTAIN SAFETY CONCERN & CONDITION AS I CANNOT ADEQUATELY DETERMINE WHEN THE CONDITION WILL ARISE THUS I CANNOT ADEQUATELY JUDGE THE NECESSARY DISTANCE TO BRING THE VEHICLE TO A STOP. THE CONDITION MAKES IT FEEL AS THOUGH JUST THE REAR BRAKES ARE ENGAGED, NO "PULLING" IS FELT IN THE STEERING OF THE VEHICLE BUT CERTAINLY I AM BEING STOPPED COMPLETELY FROM "BEHIND". CRAMER TEST DROVE THE TRUCK BUT FOUND NOTHING WRONG BUT I CONTEND THE PROBLEM IS SO INFREQUENT AND SPORADIC A TEST DRIVE OR TWO MAY NOT [OR MAY] EVER DISCOVER THE ISSUE I AM SURE EXISTS WITHIN THIS BRAKING SYSTEM NEVERTHELESS THE CONDITION IS PREVENTING ME FROM DRIVING THE VEHICLE FOR FEAR I OR SOME OTHER INNOCENT PEDESTRIAN OR MOTORIST WILL BE INJURED AS A DIRECT, CONSEQUENTIAL OR PROXIMAL RESULT OF MY BRAKING SYSTEM'S FAILURE(S). WE NEED TO GET THE CONDITION FIXED WITHOUT ADDING HUNDREDS OR THOUSANDS OF MILES TO MY VEHICLE WITHOUT JUST COMPENSATION. PLEASE ACKNOWLEDGE RECEIPT OF THIS EMAIL AND MY SAFETY CONCERNS/ISSUES THAT HAVE BEEN CONSISTENTLY A MATTER OF FACTS SINCE I PURCHASED THIS VEHICLE. THIS IS A CONTINUING PROBLEM. *JS

BACKING OUT OF MY DRIVEWAY, WITH THE ENGINE RUNNING, I TRIED TO STOP THE VEHICLE BUT THE BRAKE PEDAL WAS SPONGY AND PUSHED ALL THE WAY TO THE FLOOR WITHOUT STOPPING THE TRUCK. I HAD TO CONTINUE TO PUMP THE BRAKES AND ATTEMPT TO STOP THE TRUCK UNTIL IT FINALLY CAME TO A REST IN THE STREET. IT WAS AS IF THERE WAS NO POWER ASSIST TO THE BRAKES. THE BRAKE SYSTEM THOUGHT THE ENGINE WAS OFF, DESPITE THE ENGINE HAVING WARMED UP FOR ABOUT FIVE MINUTES. *TR
