I would check my master cylinder.
It has 2 parts one for the front and the 2en for the back
if u r holding on the brake and it keeps going down and builds when u pump it up. One of ruber seals could be bad and letting the fluid bleed off.

Dirt and rust in the master cylinder will cause this.
If u think this is what it is and u r game to try u could take it apart and give it a good cleaning.
I've done this a number of time and it has worked.
Hope this is some help
