ABOUT EVERY 4TH TIME I BRAKE WHILE BACKING UP, THE BRAKES UNDER VERY LIGHT PEDAL PRESURE,ENGAGE EXTREMELY HARD. THIS WILL CONTINUE EACH TIME THE BRAKE PEDAL IS TOUCHED, AS IF THE PEDAL WAS BEING PRESSED VERY HARD WHEN IN FACT, THE PEDAL IS LIGHTLY APPLIED.

THEN, THE BRAKES WILL ACT NORMAL A DAY OR TWO, THEN THE SAME PROBLEM RETURNS. THIS CAN BE WHEN THE CAR HAS JUST BEEN DRIVEN AND IS HOT, OR COLD AFTER BEING PARKED, THERE IS NO PATTERN. WHEN THIS OCCURES, THE CAR WILL STOP ABRUPTLY UNDER THE LIGHTEST OF BRAKE PEDAL PRESSURE, MAKES ME LOOK LIKE A FIRST TIME DRIVER.
