There are posts on replacing the boot and seal, as well as posts on a damaged bolt threads. What I have not seen is data on the seal parts where the parking brake comes into caliper. My rebuild kit has multiple parts associated with this. Car is an 04 with 100,000 miles. Fronts were dragging, rebuild fixed it. Rears are dragging (e-brake adjusted, calipers rotated all the way in and slots lined up) so I ordered the rebuild kit there too. Just wondering what I am getting into if I go after all the seals as opposed to just the dust boot and caliper seal.

Thanks in advance.
