When building my car, I found it very useful to cut out a rectangle from the trunk to access the rollbar kickback support bolts. This allows them to be installed and removed by one person easily. I would imagine that a similar access hole could be made for the rear brakes, but probably isn't that necessary. Notice that the hole I cut is completely hidden by the fuel tank once it's installed.
