Aftermarket MC brake issues

Probably beating a dead horse but cant bleed pedal going to dual reservoir
disc brake all four. Either MC junk or I should quit hobby......

Bled MC. Bled each line 50 times. No pedal unless pump a few times.
Even bled each 1/2 of MC at a time????
Was told stock single pot MC brake rod compatable....

Thanks for medicinal advice...

I had a similar problem on my dart going from single pot to duals. turned out the master cylinder was leaking back a bit. I either had a bad one from the get go or forgot and pressed the pedal all the way down before completely bleeding the system (which according to the manufacturer is a no-no).
