slack adjuster

Today and friends go out to play, on the way back, the car broke down on the halfway, but friends inside slack adjuster, pretty soon the car repaired, I said to my friends, my family also has slack adjuster, a friend told me to slack adjuster inside the car is a bit better, if what is convenient, listening to a friend to say so, I think the slack adjuster inside the car better, after friends before I told her to go out to play when the car broke down, so she waited a couple of hours, I also do not like to meet friends encounter things, it seems every time when going out to play, must prepare some necessary supplies.
