I am in the process of restoring a Mitsubishi GTO, who's brake lines have rusted. I'll be using NiCoper lines, replacing the Master Cylinder, removing the ABS modulator (also rusted and can't find a new one anymore) and possibly the Vacuum booster.
The car originally had 4 lines coming out of the ABS modulator, one to each brake caliper.
I'm thinking of buying a proportioning valve that isn't OEM (the OEM has 4 lines, one for each caliper), such as the Wildwood tandem kit, which has two lines for the front, and only one for the rear, after the adjustable proportion valve.
Should I just run one line to the rear, and use a "T" at the end to go to each caliper? Or should I run two lines using the "T" from the proportion valve?
How any of those chances will affect braking, considering that the OEM has 4 lines (even the non-ABS OEM has 4 lines going to the rear). I can't use an adjustable proportion valve for the rear brakes with the OEM, as I'd need two valves, one for each brake, and then I doubt I'd be able to match the pressure of rear right and rear left if I took that approach.
