Hello,

Just so we cover the basics, after replacing the calipers, did you bleed the brakes?
One of the common causes of no pressure on brake pedal or pedal going to the floor is due to air trapped in the lines. By bleeding the brakes, you can get those trapped air out.

Other reasons for soft pedal can be bad master cylinder, leak in the brake system.

I have attached the bleeding procedure below.

Please let me know of any questions.
Thank you.
