Problems with new front brakes

[Ackattack]

Yesterday I changed out all the front brake components on my 69 (disc brakes from an '80). I got new rotors, bearings, seals, dust caps, calipers, and hoses.

I got it all installed and bled and went for a test drive.

It seemed to be stopping fine, except it would pull to the right pretty hard. Also as i was driving around it was pulling a little to the left or just kinda wondered around like it was out of alignment. When I got home I took a look at stuff and you could see that the left side was getting hot. I touched the caliper on the right side and it was warm. The left side was hot.

So it seems that the left side is frozen. So do you think I should just take it back and get another new caliper or what?

Thought I'd ask before I just take it back.
