I get brake caliper grease at Advance Auto and apply it to the back of the plate where it contacts the puck and on the pegs that go through the plate. It is sticky and it lubricates those parts well. (This does not come in contact with the aircraft specific brake fluid). Those mounting bolts will loosen over time and will have to be tightened down, you'll know when your wheel pants start to wiggle as you are taking them off.
Here is some info to keep in mind also. When you remove your brake pucks in the future to clean them be sure to put them back in correctly, o-ring side first. They can be put in the other way, but after the first few time that you use them, the o-ring will come out to far and you will lose all your brake fluid and you will have no brakes.
