Going to swap in a new set of pads on the 20v, bleeding BTDT's?
I know the ABS system on the 20v can be a bit finicky, anything to watch out for when I toss in a new set of pads?
On some cars you need to open the bleed valve on the caliper itself while depressing the piston in to the caliper to avoid having a backflow issue through the ABS pump. Same on the 20v?
Also I remember there was a bleeding sequence you had to follow to get it to bleed properly. I have a pressure bleeder, just dont know the sequence to go in. Anyone have a bentley handy?
As always, help is appreciated.

Yes, open the bleeder before pushing the piston back.
Backflowing crap into the ABS pump SUCKS. 
So, the order in which you do it is furthest caliper first, nearest caliper last. That would mean, in general. that the driver's side front is the last. Except on a hydraulic clutch car, in which case the clutch is the last in line.
The rears are tricky. If you follow the lines, look for the longest run to find your first bleed. In the UrS car, the driver's side rear is furthest away from the MC, if you follow the lines under the car. I haven't looked at my 90q20V, so I don't know on our car.
And yes, power bleeder FTMFW!!!
