Early on, it will seem like this doesn't work at all, especially if you are up against a champion like Fiora or Kled, Braum does not like early 1v1s in the top lane, however if you have your jungler camp you until you get 2-3 kills you can snowball hard with Phantom dancer

It's really easy to team fight with this build as you are getting stuns out every second, Start as usual by focusing the enemy carry and landing just one AA on them and GG you have won the teamfight, when at the start of the teamfight try and land as many hits as you can on as many enemy champions and you basically get a team wide stun and then you can ult to keep it going while still Auto Attacking and stunning some more.

Pro- melts tanks post PD and IE. Can dish out 3000 damage in about 5-6 seconds. Easy to get S+ on this build as most people are terrible at Braum top. ALSO you should play him like you do trundle... Lose lane, then split push. With the attack speed and damage you have at lvl 18 its dang near impossible for anyone to stop you even if they are hugging turret. (Its why sunfires cape isnt in here and the damage is so high you kill them even if they get you to 1/4 health w/o you doing anything.
Cons- Blinds hurt, a lot. Also he is a little squishier compared to other braums.

Farming is pretty easy with Braum especially if you can land a Q from a distance. But it does take some time to get used to, so practice stealing an ADC's farm and you'll learn pretty well. Just remember the combos under turret. Melee Minion 2 shots then AA, Mage minion AA, shot, AA and siege minions... Just eyeball it :). His clear becomes really good post Stattik Shiv, so if you are falling FAR behind in farm (don't count it till its like a 30 farm difference) get Stattik Shiv.

I have not tried this in ranked yet, but will keep you posted if I ever do.
