Air in brake line problem

Ok So i did a number of things this weekend.
Replaced lines with SS lines.
New rotors
new pads
painted calipers black

My starting process yesterday was removing the old brake line, then removing the caliper. This basically drained the reservoir and the old fluid. I then pushed the piston back on each caliper on my bench and the extra brake fluid in the caliper squirted out.
Painted them, let it dry.
Put them back on. Now I completely forgot to mark each one where it came from. They do look identical.
Put new pads/rotors on and bleed them.
Cracked all the bleeders open to let the new blue fluid get to all corners and flush out the old stuff.
Then I closed the bleeders and went on to bleeding each one.
On the passenger side rear caliper I could never get all the bubbles out. Tried to drive it a couple feet and the car freaked out with brake warnings etc.

I read about someone who had the rear calipers switched by mistake. So i flipped them but I have the same problem on both calipers on the rear.

Any ideas?
I've been using a Motive Pressure bleeder.
Could I have screwed something up using this process?
Could the fronts be switched? Would it matter?
Is this an issue with the abs ?


Thanks

the bleed valve should be at a high point on the caliper, if it isn't they are switched left to right.

you may have air in some ABS module, which will be tough to bleed without putting the car in a mode that triggers it (dealer).

I found the area in INPA with my coding cable to activate this pump.
There is actually a procedure for each corner which tells you do hold the brakes, on and off while it activates the pump. Pretty neat. Seems like it worked!

If anyone else is interested in activating their abs pump while bleeding their brakes follow this thread.

Will do. I think it should be good now. Pedal feels good. Must have been the air in the abs.
I may require the vac bleeder on the clutch when I do my clutch next month

clutch on these cars is a bitch.. you need to be 1000000% sure you have the res. filled to the top no matter what, since the clutch fluid pulls from close to the top..
