Bad pulley , bad rod ? also, brake fluid keeps leaking!

how do I tell if it’s as bad rod or pulley ? Why does the brake fluid keep leaking ?

your post makes no sense, you know what you want to ask , but nobody could guess what it is from what you wrote.

Push rod? Tie rod? Con rod? Nimrod?
Idler pulley? Tensioner pulley? Drive pulley? Guillotine pulley?
