I have bled my brakes before the standard way at the wheels. However what's the procedure for bleeding them at the master cylinder?
you can also just use brake line and fittings and plumb them up and back into the master cylinder bowls. keep the fluid level up, leaving about 1/4" from the lip. press in with a #3 phillips screwdriver in the pushrod hole. it will go in pretty far, but will eventually get to the point of being hard to push in. at that point it will only go in about 1/8-1/4" and you will see only a stream come out of the bowls and no more air bubbles.
This is exactly how I bleed a master cylinder. I cut off the first 6" of brake line off of a parts car and this is what I use.

Your right you don't what to recycle the old fluid back thru the system. I was speaking of a new master and I am stuck bleeding by myself that is another reason why I use the "tubes". By the way your method of the jar and clear tube works good for bleeding at the wheels by yourself. As long as the tube is below the level of the fluid in the jar you can just pump away without getting air back into your system. This is what I use.
