Adriver purchased a new automobile from a car dealer. within a few days of the purchase, the driver returned the car to the dealer for repairs because the car kept pulling to the left whenever the driver applied the brakes. the dealer’s mechanic readjusted the brakes but did not detect any other problem with the brake system. the dealer’s mechanic assured the driver that the brakes were fixed and, even if they did pull the car to the left again, the brakes would still allow the car to stop. the car worked fine for two days, but then the brakes started pulling to the left again. as the driver was driving the car back to the dealer’s shop for further repair, he saw a pedestrian crossing the street. the driver pressed his foot down on the brake pedal, but the master cylinder failed, and the car would not stop. the driver’s car struck the pedestrian, injuring him. if the pedestrian sues the driver for his injuries, who will prevail?
