I've changed pads, rotors and bleed system using vac system and I still have weak frt brakes. I've done the search with no results. Is this an inherent problem with kdx's, btw mine's a 99 220 or can something be done. My 01 kx stops on a dime with very little work. Whereas the kdx, I gotta pump the thing to brake...they hold but not hardly at all....what should I do?
