are you sure you swapped all the caliper hardware and lubed the slide pin that the caliper mounts to so the caliper can float back and forth properly?

Good evening,
If you replaced all those item then the issue lies with pressure in the line not being released.
That pressure is most likely from the ABS hydraulic unit. There are valves inside the unit that release pressure when you take your foot off the brake. These valves get clogged up from dirty fluid from the fluid not being changed at the right intervals.
You most likely need to replace the ABS unit.
