Front Brakes Locked Up/Slightly Engaged?

So I'm not sure if this is a problem with my bike specifically or if it's with all VN750's. The front brakes are (what I think is) slightly engaged, making the bike very hard to push from a standstill.

This is what I bought and changed out:
Both front calipers
Brake lines
Master cylinder/brake lever

If I take off both calipers, I'm able to push the bike freely without resistance.

I am at a total loss here. Please someone help

hmmm, dunno. 2 sets of bad calipers? 2 sets of bad brake lines? 2 bad master cylinders?

what I have an issue with is my clutch has a shiat ton of drag. I can barely push my bike if its in gear and I have clutch pulled.. pop into neutral, no issues.

give it the GAS and wear 'em out!

I am assuming you compressed the calipers all the way before installing and then bled everything properly to get the air out and to get everything working. If there is air in the system or the brake fluid is low or whatever, then when you release the brakes the master cylinder cant relieve the hydraulic pressure in the caliper to disengage the brake pad.

Is there something wrong with your rotor maybe? If everything is new and is installed correctly, then that is the the only other part of the system. you didn't put your wheel on backwards, did you?

The pads always drag a bit against the rotors. So when you say hard to push, I assume they are dragging a lot. But "hard" is subjective. Bleeding the brakes properly should help, as is making sure the master cylinder is letting the fluid back in when you release the brake lever.
Did you remove the front wheel?
If you changed all the parts listed, were they with new or used parts?

Guessing it was doing this before you installed all those parts? Why would you assume they were bad to start with?

Definitely in neutral.

That's what I didn't do! I didn't compress the calipers before putting them on. Silly me. I'll be trying that this weekend.

The master cylinder was new, the brake lines and calipers were off an '06.
