A (possible) new brake bleeding technique

I just finished converting Minx's Hyosung GT650R to a GT650RS (fully-faired with upright handlebars), and tried a new technique for bleeding the front brakes that seems to work quite well.

Go to this page and scroll down to the "Brakes" section if you're interested. It takes about 5 minutes to make up the adaptor, you just need a bit of stiff sheet steel or aluminium, and a bicycle tube.

Novel . There's a similar method where you pump pressurised fluid from
the brake calipers (back priming/back bleeding I think it's called)...
but the old fashioned method has always worked for me.

 

A good way of getting rid of the older fluid in the system, but I would
still prefer the old way of refilling
As air travels north, leaving it overnight would expect the fluid to travel
down and settle

 

I usually use the old-fashioned method too, but for some reason the master cylinder on this bike just refused to co-operate. I originally thought that something must be wrong with it, but when the replacement master cylinderfrom the wreckers had exactly the same problem I decided that I needed to use a different approach.

I would do that but I've misplaced my compass. The old method usually
works for me but I've had two occasions when it didn't. Once on the
front right on the Cali (the one that's integrated with the rear) and
once on my dad's 1943 Jeep. In both cases I reverse bled the brake
using a large syringe and a piece of tubing.
