Hi,
First, if you replaced the brake calipers, it is necessary to bleed the brake system. If at any point the brake master cylinder is drained, then an automated bleed for the ABS needs to be performed. When this is needed, oftentimes with the engine off, the brake pedal can be pumped up and feel solid and then go to the floor when the engine is started.
On this vehicle, first, you must manually bleed the system. If you look at the first two pics below, they contain the directions for manual bleeding.
Once that is complete, you will need to perform an automated bleed procedure. This requires a scan tool which can communicate with the ABS module.
If you look at pic 3 below, it provides the directions for the automated bleed.
I hope this helps. Let me know if you have additional questions.
Take care,
Joe
