Where to find a full set of T-60 power armor in Fallout 4?

the concord one is T-45, which is why it falls apart. easiest complete T-60 is joining the Brotherhood, Proctor Teagan on the Prydwen sells the pieces. suits you find in the world get better as you level, so the mid game turns up more of them. keep steel on you, you repair the broken pieces at any power armor station.
