Daniel, yeah, it's pretty straight forward process. It does look like you have some serious rust. But, in my opinion, you should be able to clean it up pretty good with a wire brush chucked in a drill or air powered die grinder. After I cleaned mine, I got some quality caliper paint, painted them, and the bracket also. After paint cured, I put the new seals and cleaned up piston in the calipers,
Installed everything, and blead the brakes. Ta da!
