I use to use an mustard plastic bottle with a rubber hose connected to it. Fill the bottle up with brake fl. and open one bleeder at the wheel cyl. and connect the hose to the bleeder. Squeeze the bottle, forching the brake fl. back up through the system and you will see air coming up into the resviour. Close the bleeder and take off the hose. Do both sides a couple of times and you should have a good brake pedal.
