First off, I hope I didn't miss a more appropriate area to post this. So I mounted a new 3-Speed hub with a coaster brake on my daughter's bike (it's a heavy steel bike). The hub was difficult to fit in the dropouts but didn't require tools. I did have to manually pull the frame apart to get it started but that was it. Once mounted, the wheel turns much more sluggishly than I'd expected. To the main point though - The coaster brake in largely ineffective. I can get the bike to stop eventually but my daughter is going to have to stand on the pedal just to get any decent reaction at all. I've been all over the interwebs but must be entering the wrong search criteria; I only get responses regarding hub overhauls. This is (again) a brand new hub. Anybody have any ideas?

Been a couple of hours. I loosened the cone (only slightly) on the brake side. Not saying I know what I'm doing, but that's what I did. The wheel turns much easier now but the brake problem is unchanged.
