Could be anything from the shoes to the master cylinder-check it all. Whatever it is it shouldn't be too hard or expensive to fix as long as it's not everything like with my 82 CJ7 I bought a while back. It looked like just a minor leak in the master cylinder that could wait till I got it home-NOT
Turns out half the brake system was installed improperly and it cost me almost $400 to fix/replace. If you know your way around the brakes it shouldn't be that bad. Just make sure you look it over real well. Give
Jeeps-Offroad a look. There's a wealth of info there. Happy trails.
