Find someone with a pressure bleeder. It holds a gallon of fluid and you attach the lid to the master cly and turn on the power bleeder.It pressure bleds the lines in minutes. I have used it for over 25 years and have never had a problem getting brakes bleed. Last weekend I flushed out my 74 challenger, that fluid was close to 10 years old. Took longer to attach the lid than it did to flush the brakes. I have many adaptors for all different types of master clys. Last month I replaced a master cly on a boat trailer bleed those brakes in a minute, literly.Time is money!

This is the one for dual cast iron master clys.
