One thing I noticed is that you appear to be using the bleed method used for older US cars, pump up, then release the screw, then re-tighten. Frankly, I have never been successful using this method on LBC's. I place a clear plastic tubing on the bleed screw, with the other end in 1/2" of fluid in a bottle. Loosen the bleeder screw, then slowly and evenly pump the pedal around five or six times, then close the screw, top up the master and repeat until no bubbles come down the tube. Personally, I also go under the car and tap on the lines and cylinders with a small wrench or hammer (to free up any trapped bubbles) and then bleed again.
