What's that expression? Player hater?
If you are scared of bad weather stay home, but don't take cheap shots at the brave riders who do it.
James, good you got your brakes back. Not sure what all the syringes were about.

Glad you got it fixed but the sad truth is riding without a working back brake is more foolish and dangerous than you clearly realize.
If wisdom was gained, it would be to never do that again. Back brakes can save your life. They saved mine when my fronts went out at 90mph in the rain.

Rather than the traditional method of bleeding using the lever, and opening and closing the bleed nipple in small increments - it's a method using a large capacity catheter syringe (+ hose) to either draw fluid down from the reservoir in 'larger gulps' (remember to keep reservoir topped up) or pumping/pushing fluid up into the system from the bleed nipple.
Lidocaine gel is optional...

Thank you for all the detail Wicky 
Tip: For those wanting to use this method or any method that uses a vacuum to bleed the lines, put some teflon tape on the threads of the bleeder. Otherwise, air gets past the threads and you won't know when your system is completely void of air.

The syringe method show above is what I used, except my syringe fit right into the HRC style tubing (reservoir delete). I pushed the fluid down into the tube, and it came out of the bleed nipple.
It was working just fine, but apparently there wasn't enough fluid going through to overcome the high spot and clear it out. Once I removed the caliper and set it up on the passenger footpeg the air bubble was able to travel up the line and out the bleed nipple.
Magura recommends this method for bleeding hydraulic clutches, and in fact their bleeding kit comes with a syringe and fluid. I love doing it this way, no pumping at all. Very quick, as long as you don't have a high spot to overcome.
