OK, some of you know I have been working on my D60. Got the driver side axle outer and U joint on, so decided to install it in the truck...No problem...got the brake on and figured out that wacky little retainer bar thingy...all is good. Put the tire on and hey, here is what was underneath (see picture). I think the flat plate goes between the brack caliper piston and the inside pad, which I can live without, but what is this little retainer thing?
