Hey all, on my 2002 wrx I noticed that my brake fluid was low, I filled it up, and checked under the car to see if I had any leaks. I found a leak in front of the right rear wheel. The leak is due to rust (NY Winters) Does anyone know the size of the line that runs up and under the backseat? I'm probably going to flare the lines and relocate them.

Thanks in advance,
