    I have a 70 GS455 with power disc brakes. I received the car in pieces, currently working the brake system. How are the brake lines routed between the master cylinder/hold-off valve and distribution/prop valve? I have repop brake lines but they appear distorted (a few extra bends in them from as-shipped). I'm thinking they go back towards the firewall, turn downwards once they pass the booster and then head towards the proportioning block, under the booster shaft. I see in my service manual that the two lines are clipped together near the prop valve. Thanks, Tom

    The front one comes off the master, hits the hold off on the bracket and then meets up with the rear one as they angle down and behind the power booster on the way to the prop valve on the frame.

    Thanks Greg, I got back on it today. Looks like my prop valve is shot so I'll be working that this week before I get the new lines in. Thanks, Tom
