Alright so I think everything worked out. I gave the lines and calipers and good tap to get any air up the lines. I left the levers engaged over night with the MC open and it seems to be good now. I did notice some fluid leaking from the MC screws. Just to be safe I order new gaskets and MC covers. I'm a bit ticked off that the dealer spent 4 hours trying to do this and ending up blaming me for powder coating the calipers, but what are you going to do. They also snapped one of the tabs on my panels putting the screws in, but Atleast it looks good now. 

Thanks a bunch guys for all the help. I was braking like the Flintstones for a bit there.

It isn't abnormal for fluid to wick up the screws when you remove and re-install the covers. Chances are it will stop really soon.

Glad it worked. I would have thought they did a good bleed job before telling you theres an issue. Thats why I presumed it was the caliper halves not mating properly

Reality is, if enough heat was applied, the calipers could have been the problem.  Glad everything worked out.

So I've been busy and haven't had to time give an update, but still have Air in line. Everything worked for a bit but now I have same problem. I'm going to remove levers just incase that fixs the problem. I was wondering if there was a method to determine if air is getting in through the piston seals in the caliper. I could only get after market seals from Powerhouse in UK. They had OEM seals for the rear caliper and that seems fine. I'm thinking that may be the problem, but the front doesn't appear to be leaking. If I spray water on the pistons and pump the brakes would air bubbles form? I figure it would work like testing a tire for leaks.

I wouldn't do the water idea.  The air would be going in, not out.  I know nothing about this company Powerhouse in the UK, but if they sell in the western European market, quality should be good.  Do they guarantee the fitment of the seals?

I really wonder if those calipers arent warped and the faces aren't mating properly.

Good point.  Straight edge or surface plate will answer that once they are apart.  If they are not leaking they can 't be warped beyond use.

Not leaking as far as I can tell. When I get a chance I will take them off. A factory tech guy on another forum said that I need to raise the rear caliper above the abs unit and bleed the air out, then repeat for the front. I'll get it working eventually (fingers crossed)

Where is the ABS unit located? His statement isn't out of the realm of possibility, but is it possible to get the calipers above the ABS unit?

ABS unit is ~ upper rear of the airbox, so a bit of fiddling and he could get the calipers and lines higher.

Stand on your head and stick your tongue out just right kind of fiddling? ;D

Nah, not that bad.  [laugh]

Opening and closing bleeder valves on calipers hanging from a wire, and need a helper who can follow direction.

I hope I can work it out. Just like every mod I have done it is taking far longer than I expected. I always start by saying "1 or 2 hours and good as new". 3 weeks later and I'm still pulling my hair out.
