i have a 2004 Honda foreman 500,when i squeeze the front brake lever only one side the right works the left dont work.i took the left side drum off and found that the pistons dont move at all. so i bled the brakes and git them to move a little bit but not enough.bled them again and i cant get pressure back in there no matter what. there is fluid coming out of the bleed valve when i open it but cant get no pressure on the lever and the pistons wont move at all. do i have to bleed both right and left bleed valves at the same time since there connected? or am i doing something wrong.
