I think you'll need to remove the caliper and dis-assemble in order to gain access to the back half of the part you have circled. Removal of the 2 hex head bolts shown in left picture should release the caliper assembly from the knuckle. Then remove the brake pad pins shown in the picture on the right. It should all come apart then. The 1st two bolts holding the caliper to the steering knuckle should have blue loctite on them. They should be quite snug to break loose, but not require heat

 

Thank you so much for the information. I will try disassembling and install the Spring boot Bolt Kit.

 

Once I get the caliper off and have to install the kit I am curious to how that kit is installed? Looked online but can't find any videos showing how you remove the existing kit and reinstall the new part.

 

The service manual doesn't show it either. I've never had to take mine apart. I googled the part you're talking about, and it looks like the parts just screw together. There is apparently a shim or flat(ish) spring included. I truly believe that it will become evident/obvious as you take it apart. If you take good pics at each step of dis-assembly, it will help at re-assembly, in case of a brain fart. Farts happen.

 

They do indeed. Likely I can figure it out once disassembled. I appreciate your quick reply and help. Have a good weekend.
