Spent entire day troubleshooting brake bleeding problem of air in lines. Checked all fittings for tightness and redid a few. Sealed pipe fittings with white permex product specifically for this application. After discussing issue with Matco, I suspect problem was caused by not letting the pedals go completely relaxed in the brake bleeding process. Getting the master cylinder piston to the top during the relaxation phase allows fluid to enter the cylinder. Not letting them to the top may create a vacume resulting in the influx of air anywhere the cylinder can find it. A few tiny bubbles left. I'll leave it for a while
