Recirculating brake fluid

[Phokaioglaukos]

Our bretheren in the circle track world use these as a matter of course. Have you heard of anyone using them on a Porsche?

Never heard of them on a Porsche, BMW or in fact anything so it's all new to me. Great concept, little fuzzy on how it works though. Don't understand how it holds pressure, yet recirculates the fluid.

The diagram shows the return toward the master from the bleeders (I assume the bleeders are open). So when the pedal is pressed, the pressure forces additional fluid into the circuit, thus forcing the fluid in the caliper to press the pistons out. When the brake is released, fluid would return to the master via the bleeder and new return lines.

Good concept, just not sure about running the plumbing and what happens about the brake pad release from the rotor. How is the system bled from all air bubles and how is the system flushed with new fluid?

I'm very interested to learn if these are actually effective...
