Today I have a leak somewhere in the rear brake lines. 1998, 2WD, Stick shift. Can anyone help identify where the leak could be from the photos? Not sure whether to attempt it myself or take it to my local (very good) shop.

 

Probably a rotted steel brake line.

Call your shop for an opinion. They will likely tell you to tow it in.

 

Any competent brake shop can fix that for under $100, including bleeding and flush.

They have bulk steel brake tube they can bend and make it like OEM.

I wouldn't even mess with it unless you got the brake tube, the flaring kit, etc. Been thinking of buying a complete brake line flaring kit, but I don't do it enough to justify getting one.

 

The flaring tool kit is under $25, it's easy to justify its cost. Bought mine at Oreilly's and could have returned it as a free "rental" had I chosen not to keep it.
