I have used a variety of methods bleeding various calipers on lots of cars and trucks, including about over half dozen different Porsches and BMWs.

Most typically I use a Mityvac to pull fluid through... but I also use an assistant to do hand bleeding from time to time.

With the Mityvac, I try to close the bleed screws under vacuum so no air can get back in the caliper by passing along the bleed screw threads.

When I had bleed, my assistant is not permitted to pump too fast or bottom out the pedal. And I close the bleed screws under pressure.

I also have and use a Motive tool from time to time. Again, with this tool I close the bleed screws under pressure.

The Motive tool works great. I know the owners of the company and they are car guys just like us.
