How do I adjust the parking brake on a 2002 Mustang

CJ Medevac-- THanks for your response
Great video for the rear brakes but does not address e-brake. As if they never need fixing.
I have done this on other rear disk cars (1990 Miata), I just can't find accurate info for my car. Where is the adjustment done, at the wheel, at the lever or somewhere in between? I have heard some people say that they are not adjustable or self-adjusting, and some say that the adjustment is inside the cabin and you need to take off the console. This is why I am confused.

I do appreciate your help! I am just a little frustrated. I watched that one already. And most of the ones sown the side. Many are for drum brakes-- done those too. Just not the same as you know.
Chilton's says that it is self-adjusting. I suspect this is for drums-- which are not available on this car. The Haine's manual is so full of incorrect info on everything I try, I am not sure why it is not in the recycling bin.
Should have bought the ford shop manual when I bought the car.
Thanks again!
