We're almost there!
I took the shims off the old worn pads and I cleaned them with brake cleaner. Then I lined up the new pads and shims and lubricated them with special high temperature brake lube. This keeps the brakes from squealing. You DON'T lubricate the braking surface of the pads, you lubricate the rear of the pads. Then if they move around a millimeter or two against the caliper when braking, they won't make any noise. So spread that grease around with my finger and then stack the shims onto the backs of the brake pads.
Put the pads in place in the brake mount assembly. There are some clips at the contact points that hold them snugly in place.
Now you can take the hanging caliper part off the coat hanger and put that over the pads and bolt that on. Make sure to remove the coat hanger from the springs. That will make a racket if you drive around with that up in there.
And put the wheel on.
Pump the pedal a few times, and go for a test drive! It stops perfectly and no squeals or anything. Doesn't pull to either side when I brake and no pulsation or vibrations or anything.
