Installed ss braided brake lines , new calipers all around new rotors and pads, I blead the system but pressure is not holding in the pedal and it's driving me crazy, checked for leaks and not seeing any! Anyone deal with this also?

 

If you bled the all the caliper to the point you drained the master cylinder then you will have to bleed the master cylinder first then do each caliper starting with the one the most far away from the master cylinder.

 

And add fluid to the master the re-bleed the entire system

 

I never let the fluid level go below the min line when doing the brake job or bleeding, I was careful to keep it topped. I just purchased a Motive Pressure Bleeder and will try that. Fingers crossed!

 

The pressure bleeder should work just fine.

 

well, I got the pressure bleeder and it did work great but still not holding pressure, at this point it probably is the master cylinder, Im done trying to figure this out, towed it to the dealership, well see what they say

 

they will say you have air in your lines and we will charge you $120 to fix it

Motive is the ticket. You had lines disconnected, which let lots of air into the system.
How long did you bleed each caliper for?
Also did you make sure to install calipers on the correct side? I know it sounds obvious, but calipers are marked left and right due to having the bleeder valve at the highest point in the pot. If you install them on the wrong side, you will never bleed the system.

 

I bought the Motive Power Bleeder and Bleed the system for probably 30-45 seconds per wheel. I bleed the system twice.
I guess I'm not sure if I payed attention to what side the calipers went on, they looked Identical to me. So you are saying that when I install the caliper, the bleeder valve should be at the top of the Caliper? Powerstop (where I got the Powder Coated Calipers) did not mention right hand or left?

 

Did you replace with the same "regular" Maxima calipers or bought some
high performance 4-6 pot model caliper?
if you go to RockAuto.com you can look at the regular calipers, they have pictures. Calipers are most definitely position dependent.
When you bought your calipers, did you get one for each position or got 2 of the same part number? If so, you could have bought 2 left or 2 right calipers.
Air will rise in fluid, so the air bleeder valve should be on top of the caliper piston body. If you installed calipers on the wrong side then it is most definitely part of your problem.

I missed the Powerstop reference.

under step 6, look at the picture of the caliper. You can see the bleeder valve, covered by black rubber cap and its on the top.
When you put the left right calipers side by side, they will be mirror image of each other.

 

I got the Powerstop Powder coated calipers, they are remanufactured factory calipers. They have 1 part number for the front and one for the rear that contains 2 calipers, rh and lh

Call the dealer and ask them to verify correct caliper position. I bet they are scratching their head on this one.

 

Wow, if this is truly the issue then what a Amateur error this was, I'll stop by the dealership today and check it out for myself.
