I got the new set of anti-rattle disc brake caliper hardware from Napa today and did the install tonight and going for a test ride in the morning. This kit does not come with any special instructions for install,so I just assume put back on as I found them right? As I took off the drivers side hardware I noticed a partial piece of what looked like what came with the new parts….a rubber band looking gasket kinda thing. Don’t have a clue where and why this goes,so anyone please chime in on how this all goes together and works…Please!& Thanks!
