Trying to ID this part???

Howdy all,
I'm working on my "taking forever" rebuild of my bike. Tore it down to parade rest back in 2004 and it's 90%. I found the attached item in the pile of parts and can't, for the life of me, figure out where it goes. I recall seeing it either on-line while parts shopping, or in the parts catalog,

but can't find it now.

I know damn well it goes on the bike....just can't figure it out. Big hole on bracket is same diameter as rear axle.

1980 FXEF-80 Shovelhead FatBob.

Thanks!

if you have a "banana" caliper it keeps it from wearing the bushing or itself because of it's weight.
Goes on the axle and the spring pushes the caliper up.
If you have a different caliper, it's useless

it's missing a rubber/plastic bumper,cap on top that protects the caliper from the spring

Now I just have to find the rubber baby-buggy-bumper. Damn thing came off the bike when I tore it down, so it must go back on it! Appreciate the assist, gang!

Can anyone on here please take a quick pick of where it goes? Driving me nuts!

I get that it supports the caliper and goes on the axle, but a pic is truly worth a thousand explanations.

You pull the nut & washer off the end of the axle which should be on the brake side and then you wedge the spring up under the caliper with flat part the springs on on top the swingarm and the end of the axle coming through the hole in it and then put the axle nut back on , come man it's about as simple stupid as it gets on those .

Those are junk and will give you grief if the caliper is sloppy on the mounts , it will cause it to lean off to one side and your pads will wear crooked , you'll loose pedal having to pump it and in some cases I've seen them smoke the rotors from the pads dragging from bound at an angle . It can lock your brake up unexpectedly seen more than few do it .

HA! That was the first cure for the rear caliper starting in 73. I first saw it in EasyRiders Magazine sometime in 75. I lost my rear pads somewhere in Sweden when the disc wore thru the pins that hold the pads in. I had to ride all the way back to Germany on the front brake. I made my springy thingy out of a NSU valve spring and angle iron.
