about the tap. there is not a lot of thread there. the t is also readily available. i think if the threads are bad i would change the t too. you should be able to unscrew the hard lines with care, the right tool and some pb blaster. i dont see any reason to change all the hard lines unless they are all leaking. they dont tend to rust all that badly. when changing the flex line you prob disturbed the hard line.

brake lines arent too difficult, but you have to be careful and take your time.

good luck
