The brake lines on my 92 non-turbo talon running to the back axle are rotten and are leaking. I'm going to attempt to replace. I'm likely looking at replacing the entire brake line system to the rear of the car. Has anyone attempted this. Can you tell me:

What diameter of brake line do I need?

Has anyone been able to source pre-formed lines, eliminating the need for me to have try and bend my own?

Help!!
