I do like all these guys do, but a lil better. use a vacuum machine, but bleed every joint, not just at the caliper. So for my setup that's once at the master, three at the tee, and one at each caliper. Plus if you get SUPER frustrated, let it sit for along time. Almost never got my Galfers bled, but I let them sit for a while and eventually the air rose to the top and then bam! light switch braking.
