While coming to a complete stop at a stoplight, the car suddenly moves forward while brakes are applied. Then moving slowly car is placed in park and continues to move. Finally coming to a stop again after rear ending a tractor trailer.
Car seems to stop now with no problem.
Is this a master cylinder problem?
