I was bleeding my rear brakes, and had a hard time getting the brake line back in. I think I did nearly everything I should not have. Now I need to replace the back left brake line but I cannot remove the bolts as they are completely stripped. One is entirely stripped (circular now, and slightly bent) I took an electric saw to the metal hose, but I cannot get the stripped bolts out (so far I have tried lubricant and tapping). I have posted pictures. What should I do? Is this a lost cause and I need to take it in?

 

welcome to the forum. your third 3/3 picture, get a pair of vice grip and make sure you know how to use them and clamp and crank the part out. tap with a light hammer lightly on the vice grip as you are cranking it off to break the locking force. on the broken hose end, you may need to take it out of the clamp to get access to the other side. one side held with a flare wrench and the other with a vice grip. go to the auto shop and get the proper wrench to hold the other good side with the flare wrench.
