i was wondering if my emergency brakes need to be tightened. i have fairly new brakes both front and back. but lately (last week or so) it feels like the emergency brake is losen up a little bit. i always use the emergency brake when i park the car, not only in a hilly place, but even if it;s perfectly leveled. i know it;s not neccessary, but it;s a reflex now since i always drove manual cars. but now i can feel the car roll a little bit when i park at a slight angle. what';s the deal, do the emergency brakes need to be tighten? is it something i can do myself, the dealer or just any brake shop?
