Hayes 9 rebuilt caliper now wont bleed properly

had a problem with the from brake on my bike wouldnt bleed fully and could hear a faint squeek from the Master Cylinder Cap assumed that was the problem so fitted a new one.
was better but still wasn't working properly so swapped the levers over and re bled
back brake was still nice and strong front was still weak
Looked at the pistons one wasn't sitting properly and was sticking
So rebuilt the caliper, now its worse than before cant seem to get it to bleed properly and brake is weaker than ever :?

Just got a fresh bottle of dot 4 to see if that was the problem.

when pulling the lever when squeezing the syringe I can feel there is pressure there but when I close the bleeder and refit the cap the brakes don't work :?

changed back to Hayes bottle using Hayes bottle to refill and they are working better.
The last time I tried the syringe I tried "degassing" the fluid by using a small mole grip to clamp the pipe - there were a lot of bubbles that were stuck to the syringe wall that wouldn't release. these bubbles looked as if they were trapped in the walls of the syringe. when I tried degassing the fluid the only way to describe how it looked was like champaign but no matter how hard I flicked the syringe the bubbles wouldn't rise to the top and burst they would form a "head" also a lot of bubbles wouldnt move at all either.
As the syringe used to work better I'm wondering if the dot fluid has over time degraded the plastic body of the syringe?
Might get another two syringes keep one for DOT and one for LHM
still one piston is a little sticky so I'm going to swap the callipers over, then re-bleed so the one that works better is on the front and the that doesn't grip as well is on the back.
