But why replace when rebuilding is easy and the cost savings are great?
If the caliper was cracked and leaking like another members was I'd say yes, but in your case no, just refresh.
I have faith you can do this.
You're probably okay just rebolting the two halves together, I was agreeing with Alex and taking it a step further.

Lastly, can I use DOT4 brake fluid?

In a rebuild kit it will have a large square cut seal (piston to caliper body), a small square cut seal (in between both caliper half's (which caused the leak when you took the bolts out)), a dust boot and a spring steel retaining ring which holds the boot to caliper body.
If your piston is original look for wear marks or pitting , if so I'd replace with a stainless steel piston/puck.
Brake fluid is hydroscopic (pulls H2O from the air). Even in dry Arizona I'd use SS caliper pistons.
This is a fun, easy project that ANYONE can do and is in the skill set of almost all weekend wrenches .
Clean the caliper with degreaser, soap and water. Rinse well. If you don't have compressed air, sneak into house and put in toaster oven or regular oven, warm till dry. Your wife, your life (don't get caught).
Use fresh clean brake fluid or assembly lube if you have it. You could even send your calipers out for plating or power coating.
I'd use anti-seize on bolts that hold the caliper together and the bleeder. The groove where the square cut seals fit must be very clean, this is a must. There may be black crud that needs removed. A pick set to chip away and some scotch brite to clean the grooves are helpful.
If you take pictures you could write an article .
PS, when rebuilding at my old shop we had two sand blasters. One for general/rapid cleaning and a second with a very fine abrasive for final finish before plating or paint. Unless you are 100 % sure you're able to remove all media do not attempt. You should be able to get it clean with a wire brush and cleaners.
You've got this !

The caliper is made in two halves, with a drilling between the two to allow the brake fluid to travel to and act on the outer piston.
This drilling is sealed by a small rubber ring clamped between the machined faces of the caliper halves.
By erroneously splitting the caliper, there is a chance that you now have a fluid pathway to the outside world - and the only way you'll know about it is during the accident...
The rubber seals are pence in real terms, and it is certainly worth changing the one on the caliper you've dismantled just to be safe.
All you need to do is dismantle it again, clean everything thoroughly, replace the seal and bolt it back together again.
I'd leave the pistons well alone unless they are rusty and siezed, though I can highly reccommend the Mini Magazine technical article on changing the pistons if you decide to do that.

If they haven't been upgraded our host sells stainless steel caliper pistons and rebuild kits. Doesn't take much time or money and having 100 % confidence in your brakes is worth ?
Priceless .

I haven't touched the rear brakes. Do I still have to bleed all 4, starting with the farthest from the resevoir?
Thanks

Is this never going to seal right again?
