About to run the brake lines and have a couple of issues. Front calipers are Hyundai Stellar ( girling cortina copies) rear calipers are Toyota Corolla GTS (1986). I tried a tap in both and a 1/8" NPT seems to fit, but I would assume both are metric. Anybody been down this road before? Thanks

Most likely 10mm x1.0 but could be 10mm x1.25 or 10mm x1.5
Cheers.
