Next is the arduous task of fabricating the mounting brackets. The material in question being 3/8 thick angle iron I had access too already.
I started this process by locating the caliper properly on the rotor. Using the correct size feeler gauges taped to the pad pins inside the caliper; this is how I centered the caliper to the rotor. Then I used shims I had previously purchased (toilet shims lol) to properly locate the caliper-to outer diameter of the rotor clearance. All while giving consideration to the pad contact area on the rotor.
Once the caliper was correctly located I used my transfer punch set to find and mark all the mounting holes that needed to be made.
