Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
If this is both front brakes that are engaging and staying engaged and the calipers have been replaced this fault is caused by the master cylinder itself.This master cylinder has cups/seals in it that when the brakes are applied push fluid through the system to apply the front brakes.Then when the brakes are release the cups/seals pull back and release the brake pressure which in turn releases the brakes.What happens is these cups/seals swell over time or with the incorrect brake fluid used and cause the brakes to stick on like this here until the vehicle sits and the cups/seals slowly release to allow fluid pressure release.This is a common fault I have run into and in most cases is due to either fluid contamination or incorrect type of fluid used but can also fail on its own with the master cylinder needing replaced.
