Thought I'd "roll the bones" and see what it takes to adjust the rear calipers without buying a special tool. Turned out pretty sweetly. The needle nose approach was not simple but fortunately my pistons were not seized up or difficult to move. Drivers side went in about 3 turns, passengers side about 2. Pumped the brakes twice and thought it felt good. Gave it a third push and could tell it positioned "up".
Took it for a quick drive and I could tell straight away that my brakes had better grab and a check on the hill of the driveway confirmed it.
2007 2.4L N/A. Stock + some pretty crap.
