After getting my front end aligned today the mech notice that my brakes are very weak and he offered to check them for me. He checked out a couple of things (its not the vacuum)and he says he thinks when I put on the new booster I didnt adjust the rod that goes into the master cyl correctly. He probably right I just put it on out of the box Can anyone tell me how/how much you adjust this rod? How do you know where to set it. More in/more out?? Opinions.
