Well I've had my TJ for about a year and a half with no major issues, just normal oil changes and gas. This morning I went to get in it to come to work and the brake pedal hit the floor. I get out and it is pouring brake fluid from up near the firewall. I didn't get to look further than that because I was running late for work. I am assuming it is the brake master cylinder. I've done a lot of car projects but I have never replaced a brake master cylinder before. In the few Jeep writeups I read (non of which are super helpful) it mentions bleeding the master cylinder on a bench. Uhhhh... What? How is that done?
I can't imagine this is that hard of a job but I can't find a clean write up. And when I type in "brake master cylinder" searches bring up clutch master cylinder. Is a brake master cylinder called something else?

it's a pretty easy job overall, you can handle it i'm sure
here's a youtube video on bench bleeding, also easy

Ok I just got to poke my head around in there. It looks like it is from the line to the drivers side front brake. The brake reservoir is not totally dry, but close. Do I still need to bleed the MC after I replace the line?
EDIT: further inspection it is now a line going to the passenger side. I am tracking it down now.
So, it was the passenger side brake line. It is all steel and was a PITA to get out from the Jeep. Now that I have it out I think the only way to replace it is to bend a new line. Anyone know for sure? I've never had to bend a line before.
You needn't bench bleed if you build a reverse bleed setup(push fluid up through the bleeder with a big syringe).

Here you go!. Per bent line. I'm guessing you might want to replace both if they're getting rusty
