No need to go turning off the back of the brake. You should only have to chuck up one item to install a brake, and that's the barrel.
That's what I'm gathering from the recommendations.
The brake had a frosted finish to begin with and I wasn't sure how it would polish and I don't really like polishing on the lathe. So, I was hesitant to turn the OD of the brake.
I think it worked out in the end. But, I've learned a few things here that should help out next time.
