For bike brakes, I like me odorless mineral spirits. It doesn't attack paint or plastics, and it dissolves practically all oils, waxes, and greases. Clean the rims and the pads, and you're good to go.

However (added in edit):

Don't soak decals in solvent. Be careful around them. Odorless mineral spirit tends to dissolve decal adhesive if left on long enough.
Denatured alcohol can wreck the surface of decals. I have had bad luck with silvery decals getting ruined by alcohol.
Otherwise, odorless mineral spirits and denatured alcohol are pretty safe ways to clean plastics and painted surfaces.
Acetone and ethyl acetate (nail polish remover) will destroy decals and attack some paints and plastics.
Methylene chloride and tetrahydrofuran; first, why do you have that stuff in your garage? These will go after decals, paint, plastic, and powder coating. They cause cancer and reproductive harm. They can also destroysrubber brake pads and some tires.

When in doubt, test it on a small inconspicuous area. The day it destroys something that the world will never see is the day you will be glad you did.
