Brake Booster Adjustment Tool

Brake Booster adjustment tool should be fairly universal. Tried to make it out of things most people would have laying around, so the rod is a 16 penny nail. Mine was 84.5mm long. Others should be very close and could be filed a bit if needed to be the exact length. The screw is just an m3. 2 files available; one for a regular hex nut, one for a brass insert for the m3 screw.
