#14, #15, #23, and #24 are what you need to keep the brake pads from rattling around. You can buy them from your local auto parts store. They are called pad clips/anti-rattle clips/caliper clips. Don't go to the Stealership, they want $5 a piece for those, the auto store should have them for $5 for all 8 that you need.
I had the same thing happening to my VX with the pads, I'd describe it more as a wooden stick that sounds like it's banging on the front knuckle over ever little tiny bump in the road, it's annoying.
But if it truly sounds like nickels in a coffee can, then it could be a trans bearing, check that after you get those clips.
Hope this all helps.
