1993 Toyota Camry electrical system problems

(1) break is not functioning properly, break light is showing, after adding fluid light disappear and function after several pumping, pushing of the break down and releasing towards up. Seems limited friction to function the break. Went to mechanic shop, was unable to detect, rather filled with break fluid and injected break fluid through physical pumping to the break. Works until few miles drive , after that break fluid level start falling down and break start to loose its function.
