My first guess is bad calipers. What brand? Do they match what is/was on the car? These days brake calipers are really pretty straight forward.

How much flushing did you do? How much brake fluid did you go through? Have the flexible hoses ever been replaced? I had seen a car with very weird brake problems after a caliper replacement and it turned out to be bad hoses.

The only other thought I had is are you doing anything out of the norm? For an example, are the pads the correct ones for the car? They aren't some unusual second or third tier type/brand? They are thick enough? My concern here is hyper-extension of the caliper piston.

If everything else is as it should be, sounds like your supplier needs to provide you with a SAFE replacement. The safety word REALLY makes vendors take notice in my experience.

Keep us posted,
