Brakes pulling to one side

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there

Glad you found the problem.
Well done on the write-up too.
Can I suggest something?
You once told me that the part numbers for the two metal sliders were different, even though they looked the same to me, so it must matter that they don't get mixed up. I didn't measure them, I just replaced the damaged rubber on mine.
Usually when I rebuild a calliper, I pump some fluid in to make sure the pistons are going to come out, and pump any seized ones right out whilst the brake pipe is still connected. Lucky that there is a nice hole to drift these out with on the Jimny.
If the pistons are pitted, and the pitting will go through the fluid seal when new pads are fitted they must be replaced. Sounds as though you caught yours in time.
Enjoy the rest of the job, if you don't have ABS, the brake bleeding is easy.
I made a big mistake doing mine. Although I only removed a front calliper, and didn't therefore need to bleed the rears, I broke rule #1 (DON'T MESS!) and thought I would bleed the rears, and flush the old brake fluid out. There is only 1 nipple, on the passenger side, and it came undone slightly, then seized solid with fluid leaking, and wouldn't move either way. Naturally, this was at 5:00 on a Saturday, and I needed the car on Monday.
With prayers to various Deities I forced the nipple out, expecting from the feel of it to remove all the threads from the casting with it, cleaned it up with a wire brush, then put it back in, bled the rears, and nipped it back up. It hasn't leaked or blown out-- yet
