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 you have no brake fluid leaks at all the most common cause that will cause this issue here is the brake master cylinder itself.It has seal/cups internally that weaken over time or in some cases with the incorrect brake fluid used and causes a pressure bleed down like you see here.The brake master cylinder will need replaced and bench bled then installed and the brakes bled of air from there to resolve this issue.I would double check and make sure there are no fluid leaks first.
