Have you tried gravity bleeding? Fill the reservoir with brake fluid. Then loosen both bleeder screws and let it drain while keeping the reservoir full at all times. Let it drain until you have a steady stream of brake fluid draining out each side. It may take a few minutes before fluid starts draing out the bleeding screws. Make sure you don't let the reservoir get even close to being low or it will get air back into it. When you get a steady stream, tighten the bleeder screws back up and see if you have a full pedal or lever. If not you may have to finish bleeding them by pumping the lever.new kid on block here !!!!!!! i gots me a lil problm. master cylinder on a 1990 300 fourtrax 4x4. front wheel cylinders not getting fluid. rebuilt master cyl. but cant getsystem to bleed out. what am i doing wrong ? any help will b rewarded !!!!!1
By the way, make sure you have the brake shoes adjusted up on both sides, first, or you will never be able to get a full pedal or lever.
