On the cages I bought a power flusher, connected it to the master cylinder and cracked the bleeder at each caliper starting at the one furthest from the master cylinder.SIMPLE.
below is why I feel it is a bit of a PIA (it's easier after the first time):
cover anything that may get dot 4 on it, particularly the winshield & little plastic air diverters
1- you need to remove the left tupperware
2- you should pull the calipers and press open putting wood in place to keep open
3- the little fluid resevoirs are in the abs control unit and you need to use a fitted funnel to add fluid while you power purge the front and the rear
Now to the control unit;
1- need to pull the right rear brake resiv. to a position to keep filled
2- need long small 7 mm combo wrench slightly modified by bending
3- need to purge six 7 mm bleeders on the abs control (for the front and rear) unit in proper order doing #1F & #1 R twice
hopefully you did not splash dot 4 on anything plastic or painted.
Put it all back together, not to hard but a bit of a PIA.
