I've been trying to help my friend with his brakes problem on his Dodge. The FL brakes won't engage or disengage. All others are great. We changed both calipers, the pads, and bled the piss out of them. Still having the same issues with FL brakes. Anyone got any ideas?

Am I correct FL is Front Left?
If so might be an issue with FLEX brake line - they sometimes get an internal restriction.
If something else other than Front Left let us know.....

Yes, left front. If there were a blockage or kink in the brake line, would it not have shown during the bleeding process?

Shouldn't have bled out if totally blocked - might stay applied rather than not work? Is the flex hose twisted up like a pig's tail?
That would do it,

OK, we're going to be changing the flex line. Is there a chance, also, that it could be the master cylinder?

Master? Not yet. Try this - Put pressure on it and if bleeder still puts out fluid and piston doesn't apply brake in you hands stopping rotor or wont let go the hose is fairly common reason. Twisted up I mean the hose isn't in proper position as you can put most calipers back on and twist it around once and still get them on but it's like kinking a garden hose. If so toss that flex hose as it's been stressed out too much IMO.
Is this only happening with the new calipers or the same with old ones?
IDK - try watching the caliper with helper pushing brakes. It should move a little in front of you. Rotor should be free turning by lug nut studs then lock tight by hand with brakes applied and it bled out properly. If not I can't see how it bled out fluid unless the piston in that caliper has come out too far for some whacked reason and gone cock-eyed but if so you probably couldn't put it back over rotor with pads.
Flex hose appears like just a rubber hose but strong inside for very high pressures. That can fail and lock fluid usually in such that brake is stuck on not both ways unless really wrecked or twisted up badly now and might not survive if it was. Still think it would blow out, show a bubble in hose or not bleed if hose failed.
IDK - you tell me. How could fluid make it to bleeder and not do anything with the brakes? Is the left caliper on left side and right on the right side? You can put most on the wrong side, they would leak fluid and never bleed out or work and end up with a totally soft brake pedal but BOTH wheels would be the same - not working not just one,
