Living in the rust belt has taken a toll on the rear brake calipers of my FWD V50. I'm in the middle of replacing them and ran into some trouble. The flex line going into the caliper got seized (days of PB Blaster and heat didn't work) so I tried to disconnect the flex line from the hard line. After a couple of turns, I realized that it was spinning the metal hard line which resulted in a small leak in the metal. I've taken apart/off some of the heat-shield to trace the line back but am wondering how far does the hard line go? The master cylinder only has 2 lines coming out of it - for the front and rear. Where does the 1 main line for the rear split into the left and right side? I can't seem to find this info anywhere. Thanks in advance!
