Okay, the short version is, I have a 70 Charger with the original disc brakes up front.

The calipers are the original single piston style, and the rear brakes are the original drums. It was a factory power disc car, but someone has removed the brake booster and fitted a master cylinder from a 71-74 E body.

All the lines, calipers, and master cylinder all have less than a thousand miles on them. They are a few years old however, except for the master cylinder, it's new.

My problem is the front brakes drag constantly. Almost to the point where the left wheel cant be turned by hand once the car is jacked up. The right front isn't as noticeable, but it drags too.

Any ideas whats going on here? Aside from the deleted brake booster and the master cylinder from an E body, the rest of the brakes are as they were originally.

Any ideas where i should start looking?

I would appreciate any help, thanks!
