Messed up when doing pads, rotors, and fluid, need help figuring out how to fix

[TheDoctor117]

A while ago, I did pads, rotors, and fluid at all four corners. I fucked up a few things and fixed most of them, but one thing I did was accidentally try and bleed the rear left caliper while the caliper wasn't on the rotor. I have no idea what I was thinking, but bottom line is the piston popped out. I did get it all reassembled, rebled it a few times (and have even had a shop bleed the brakes for me), and put everything back together. The brakes and stops, but under hard emergency braking, the car pulls to the left. I suspect this has something to do with me messing something up when I put the piston back in the caliper, or maybe something else. What I'm wondering is if the answer is to try and rebuild the caliper, or to just get a new one. If anyone has good instructions how to do either, it would be greatly appreciated.

I have never found good caliper rebuild kits for this car.
Rebuilt calipers are available.
I would suggest replacing the both the calipers per axel at one time.
