The one posting that I saw said 01 GT. as for the explorer parking brakes, it's pretty much a mini drum brake setup. clips, springs, etc.
here is the post from explorerforum.com
If you want trouble free e-brakes just do away with OEM e-brakes and put a set of Mustang Calipers on. The Calipers are attached to the brake cables and are adjusted at the same time you adjust the brake pads with a special tool. This is what I did and it works like a charm. Also, its a direct bolt on.
