ok so I just recently got into EV training and before I new what it did I sold the macho brace. is there any way to get it back?
You can trade for one. Otherwise, there's no other way to get a Macho Brace, sorry.
No you cannot get it back. So you have two options. One, have a friend trade you their Macho Brace. Two, buy the power items from the Battle Subway for each stat. (Power Bracer, Power Lens, ect.)
