First off all, It's just a overpriced "hope" MTB brake master with a Rekluse logo.
Second, is the worst part, the dual action is optained by changing the lid of the original foot operated master to a new Rekluse lid with a thread to fit the brakeline from the LHRB.
That means when you use the LHRB you pressurize the original master from the top, and the brakefluid reservoir is NOT designed to take that kind of pressure!! 
My friend fit the system on his GG 300 and it was actually working good, untill he while braking, heard a loud "POP" and the LHRB lost all pressure and his right boot was soked in brakefluid, the level check window in the foot master was gone leaving him with a big hole in his rear master  .. |
I have not seen this in the flesh, but...
Of course the rear master cylinder isn't designed to take the brake pressure in its reservoir (window and all), and I do not think the Rekluse design intends to use it that way either. There should be a o-ring at the bottom of the part that you insert into the rear master cylinder. At least this was the case with the previous dual action design (where you used the clutch master for the rear brake). This o-ring seals off the pressure, so that the pressure from the left hand master cylinder is routed into the rear master cylinder's high pressure circuit.
Could it be that the o-ring is missing or leaking, or that the length of the insert is wrong for the actual rear master cylinder?
I have been playing with the idea of building a similar system for my bike, so if you could give me a link to the Hope (or other make) radial master cylinder that Rekluse use, I would be grateful.
