I replaced the rear pads and rotors on my 2013 @ 67K miles. I was confused at why I couldn't get the rotors off, but eventually figured out how to loosen the rear parking brake at the star adjustment. Once I had the new pads and rotors on i flicked the star adjusted "up" until it felt tight, then slightly loosened. Well now my parking brake doesn't hold like it used to. Can i just tighten the star adjuster more on both sides, or do I need to do the whole adjustment prodedure that involves removing the lower portion of the dash like in the FSM?
