07 rear brake line leak

Hi everyone. I noticed on my way home today I would press my rear brake and get no response. Once I got in I looked at it and noticed brake fluid had come out everywhere. I'm not sure what happened but as you can see from the pictures the fluid looks to be coming from under that bolt. Any suggestions on what I can do to fix or where I can start looking to figure out the problem? Thanks

Not sure what's wrong with it, but I have a spare rear brake line that I'm willing to sell you for cheap. Had it for 30K miles and swapped it out with stainless steel braided lines.

Ride as if there is a tomorrow to live for.

That is a TON of brake fluid; quite dangerous if you are riding. So first and foremost is make sure that is cleaned off. It appears as though the bottom white line from the banjo to the caliper are not matching up. It could be the pictures but if it doesn't line up than the bolt has been backed out a 1/4 turn or so and needs to be tightened back to spec (check the copper washers are good before hand) and the brake bled. Have you messed it anything back there recently?

Thanks. No I have not but it's possible I could have hit it with my foot by accident, etc. any idea what size that bolt would be? I cleaned the fluid off already and parked the bike until I figure out what's up. Also do I need to turn the bolt clockwise or counter clockwise to tighten?

It shouldn't loosen just by hitting it with your foot. I am pretty sure its an m8, so JIS states its a 12mm head. Honestly, if you don't even know how to tighten a bolt I would take it to someone to make sure that things are all alright and bleed the brake for you.

That is a banjo bolt, not just any bolt, it is hollow and has holes drilled in it in specific spots to pass brake fluid, youd better have it looked at by a mechanic and dont ride with brake fluid on your rear tire, also that brake fluid will eat your paint on anything so I would clean it super well with some brake clean or a really good degreaser
