My Build — Disc Brake Anchor Plate issue?

caliper2Winter has a funny way of blowing all kind of things into and around the garage. Last November I took a break from projects in the garage, but when I went out there a couple of weeks ago, it was a bigger mess than I remembered it.  So, I spent last weekend cleaning (including cleaning out the parts washer — uggh), organizing and getting ready to attack my first project of the year, getting the disc brake parts cleaned up and painted.

PROBLEM 1: My parts washer repaid my efforts at cleaning by developing a leak at the base of the pump.  Not cool.  Since this parts washer is older than some of the wagon wheel trails around here, I’m not entirely sure if I can find parts for it.  It’s entirely possible it’s a custom tank.  So, I get to spend this upcoming weekend removing the washing liquid and attempting to patch the leak.

So dear readers, what’s the bolt for?  Is it important?  I’ve got two images to the right.  The image at the top shows the entire anchor plate.  The second pic highlights a correct hole and the bottom image highlights the problem and shows the bolt that should go there?  Do I need the bolt (of course, I’m sure I do)?
