Ok... I just completed this today.
First off, this is how the car looked before.
The first step we did was jack up the front of the car one by one.
Before doing so, we loosened the lugnuts.
This is the jacking point where we jacked up the car and set up the jacks in the front for the front right tire. We left it supported with two jacks just in case for a sturdier support.
The next step after that was we took off the tire and cleaned off the brake caliper with some brake cleaner that came with the brake caliper kit we bought.
Afterwards, we paitned the brake caliper with paint brushes so we have control of where we want the paint to go. The color we went with was red.
After that, we jacked up the other side vice versa and sprayed that side too.
The next step for us was to jack up the rear end of the car and set it on jacks.
These are the jack points that we used

Afterwards, we cleaned off the brake calipers and then painted them also.
This is the end results of all the calipers painted.
After that , we just put the wheels back on and voila! Job finished.
