Most disc brake bikes come with calipers that will never adjust right and stay that way. There are a few reasons for this. Did you ever give caliper screws that final torque for tightness and then they always go sideways? The problem is chiefly caused by O-rings. In a bike factory assembly line individual items of nuts, bolts, washers.. are preassembled as components. The caliper component is held together with an O-ring at the bottom of the stack of washers and spacers on the hex cap screw. When tightened part of it gets caught in the threads and the rest protrudes to one side. The cap screws must be pulled and the O-rings worked off for the bike's brakes to ever work right. I can give more. That is a good place to start. I will invite @m@Robertson to kick this thread off.
