Re: Weak brakes...What to do??
In drumbrakes the pistons get stuck in the cilinders many times. You can either replace them or take them apart and clean them. I even smoothen them using 800 waterproof sandpaper. (Don't know if many of you disapprove.) I install them using blue brake grease. Don't use regular grease! I also sand the brakeshoes on the surface where they contact the drums and on the short edges to prevent them from sqeeking.
