If we don't have references on how to do it ... first we start the caliper that is farther from the brake pump. and so with the others until you reach the brake caliper that is closer to the brake pump
I think this is probably the right answer...
The ABS module is likely a bottle neck for trapping air in all it's nooks and crannies from what Ive read....but of course, the pump to ABS block must be air free first and foremost...!
On a 4200, it means rear left, rear right, front left, front right...to be pedantic ! Luckily, with a pressure bleeder it hasnt made any difference.
I have to say , (and Ive got Brembo monobloc and other type calipers on several bikes that I have refurbished a number of times) I cannot believe how much cranking up the bleed nipples take to stem that annoying weep that they seem to do. Ive never needed to apply so much torque to a bleeder before. I started by cussing the tech that rebuilt all the brake lines recently but soon disovered that "yes"...it seems you do need to tighten them up that much !
