This project has been sitting for over 2 years and I have just got back to working the car. I bought new brake lines and am routing them from front to back. It is two pieces and I am wondering if there is any type of proportioning valve in between the lines under the car that joins them or just a union to complete the line. I have the rusted out and decayed old lines to try and compare but I did not see anything. I have tried to look at some pics online of other cars and can't see to get a good one for there. Any help or pictures would be appreciated.
