bill-
yea, i've removed the brake from an A-06b xxxxxxxxx unit.
all allen head bolts are metric (japan). and just so ya know it's pronounced "fanoook"
so ya, remove the end cap, and yank the encoder. it's of no use to ya. then, you remove the long bolts that hold the thing together, and begin prying/banging with chisels, bars ect. to break the case between the rear case and the laminations. you want to "pull" the rear bearing from it's press yet keep the front bearing in its home. problem is, the rear bearing has a spring washer in front of it, so you have to pry (easily) for about 3/8" to collapse the spring washer, then pry (hard) to actually get the bearing to move within the press.
the other beautiful part, it the coils are right behind where your sharp tools are being inserted, so be careful!
you want to do it this way, because it will leave the mags right next to the coils. i've never tried, but have read about how removing the magnet rotor from the coils/laminations, can greatly reduce the magnetic strenght of the rotor.
one the back half of the case is off, you can remove the break pretty easily. i also took the opertunity to solder/wire nut on #6 copper extensions to the three hot leads within the case. i removed the funny prug, and ran the three wires out the hole.
