Ok fellas I have a problem with 250r 1984. The brakes on the front do not stop the bike right. You should be able to do a "stoppie" stand on the front wheel by locking the brakes. I did everything your already thinking of. I sanded the disc rotor, I put a new piston and seal and dust seal in the caliper. I rebuilt the master cylinder. I bled the front brakes 30 times liquid squirts out and then i closed the bleeder. I have tried different methods of bleeding like pumping them up then opening the bleeder. I have also tried slow pulls of the handle and then holding it in till the bleeder is closed. I have replaced the brake pads with the best money can buy. The only thing i can think of is doing a reverse bleed on the system . The piston on the master cylinder goes in a half an inch before it gets real tight. On my friends quad the piston is supertight at the beggining.
