Yesterday went to 4S shop to repair, because I feel my car recently braking performance is not good, not so good, so many people tried to persuade me to the 4S shop to look at the car repair, car know that people who tell I said it was probably slack adjuster does not work, so I went to the 4S shop maintenance professionals make people look bad if the slack adjuster, then, for a slack adjuster on it, it should not take much money, I heard more at ease, thinking what a big problem as long as not all right. But a 4S shop maintenance person because of slack adjuster really bad, so I changed the new slack adjuster, I’ll open the car home, much better now.
