Berni - I started with the old tried-and-true method of pumping the brakes while an assistant opens and closes the bleeder valve at the caliper. I was never able to get all the air out. After many hours of frustration I broke down and bought a pressure brake bleeder from Aircraft Tool Supply. It’s around $90 but well worth it. I pressurize the tank, connect it to the bleeder nipple, and let fluid flow up to the reservoir. Secure a cup under the reservoir to catch the overflow. Let the bleeder tank push fluid until several ounces fill the overflow cup and you’re done!

 

A couple of notes: make sure your brake pedals are fully retracted – fluid won’t flow backwards through the system if a brake is partially depressed. Also, even under pressure, the fluid moves rather slowly. It could be a full minute before you start seeing any result.

 

Enjoy!
