Answer 1
Really hard to say without looking at the vehicle in person, but one thing that usually causes that is contaminated brake fluid. If somebody put anything other than DOT 3 or DOT 4 brake fluid in your master cylinder, the fluid can become contaminated and cause the rubber seals to swell up. -
