2014 Toyota 4Runner Brakes Problems

THE VEHICLE IS HARD TO STOP AND THE BRAKES ARE SPONGY, IVE DRIVEN A FEW 4RUNNERS AND THEY ARE ALL LIKE THAT AND ITS DANGEROUS. YOU HAVE TO PUSH THE PEDAL TO THE FLOOR. THE ENGINE MAKES A HORRIBLE TICKING SOUND WHEN IDLING AND SOUNDS LIKE THE ENGINE IS GOING TO BLOW UP

WHEN DRIVING I HAVE TROUBLE STOPPING THE VEHICLE. I HAD MY BRAKE PADS REPLACE IN FEBRUARY, BUT THIS STILL DID NOT HELP. MY BRAKE PEDAL WILL GO ALL THE WAY TO THE FLOOR BARELY STOPPING THE VEHICLE. I HAVE TAKEN IT TO TWO MECHANICS AND BOTH HAVE CONCLUDED THE MASTER CYLINDER NEEDS TO BE REPLACED DUE TO A LEAK. PARTS ALONE COSTING $2500 FROM TOYOTA.

FROM THE VERY BEGINNING WHEN I PURCHASED MY VEHICLE NEW, THE BRAKES ON MY 2014 TOYOTA 4RUNNER GRAB WHEN ANYTHING OTHER THAN LIGHT PRESSURE IS APPLIED WHEN THE VEHICLE IS IN MOTION, NO MATTER THE SPEED. INITIALLY I THOUGHT MAYBE MY MODEL DIDN'T COME WITH ABS. UPON FURTHER INSPECTION I DISCOVERED THAT IT DOES. BUT IT ALSO COMES WITH BRAKE ASSIST, WHICH SOUNDS LIKE THIS IS WHAT IS CAUSING MY CONCERN. WHEN THE TRUCK COMPUTER INTERPRETS YOUR PRESSURE AND SPEED OF THAT PRESSURE ON THE BRAKE PEDAL IS "URGENT", BRAKE ASSIST TAKES OVER, AND IN MY OPINION, LOCKS UP THE BRAKES! THIS IS TERRIBLY DANGEROUS!!!!! THERE HAVE BEEN SEVERAL OCCASIONS THAT I FELT THE SUV WOULD TURN OVER BECAUSE YOU HAVE NO CONTROL ON DRY PAVEMENT AND ALL OF THE MOMENTUM HAS NO WHERE TO GO. I COME TO A SCREECHING HALT AND THE VEHICLE IN FRONT OF ME HAS TO BELIEVE THAT I ALMOST REAR-ENDED THEM. AT LEAST IF THE PAVEMENT WAS WET I WOULD HAVE AN OPPORTUNITY TO RECOVER FROM A HYDROPLANE SITUATION. I AM TAKING MY 4RUNNER INTO THE DEALERSHIP THIS SATURDAY TO SEE IF THE SENSITIVITY CAN BE ADJUSTED OR EVEN JUST TURNED OFF. THIS CONCERNS ME ENOUGH THAT I'M ACTUALLY SHOPPING FOR ANOTHER VEHICLE.
