Figuring out how to install the brakes was a moderate challenge. On two occasions I started taking apart things that Shouldn’t Be Taken Apart, but I didn’t do any damage. It was pretty straight forward after I got through the mental imagery of what attached to where.

In this aft view, you can see the fitting for the brake line and the shoes on the rear aspect of the disk. You can also see the re-attached fairing support and clearly see why it had to be removed in order to put on the brakes. Live & learn. (If I ever build another RV-12, it’ll be a lot easier to spot the redundant assemble-disassemble-reassemble sequences.)
