Hi there. There are a few things that will cause this. Most of the time when this occurs it is due to petroleum contamination in the brake system. If something other than brake fluid was put into the master cylinder then that will cause the seals to swell in the system and cause this. If there is not petroleum in the system then most of the time this is due to a failing master cylinder. I usually check to see where the pressure is being held to isolate where it is coming from.
