Brakes

[SpadedOne]

I need to change one of my brake calipers, as it's sticking. Problem is, never worked on brakes that have ABS(always had old school cars). Is there anything different about them? Do you bleed them different? Anything I should be aware of or keep in mind when changing it out? Any info would be greatly appreciated.

FYI- it's the right rear one.

Also going to change the tranny fluid when I do it too. What is the BEST kind of fluid to use? How long should I let it drain for?
