Hello my name is ***** ***** thank you for your question.

When bleeding the brakes they have to be bleed in a certain order. Did you do it in the proper order? or did you just bleed them?

Customer: replied 10 months ago.
right rear, left front, left rear, right front
Expert:  Jay replied 10 months ago.

That is correct, how ever..just to be sure.. Which side of the car do you call the left and right? So I know you are doing it in the proper order on the correct side of the car?

Expert:  Jay replied 10 months ago.

Also do you have someone helping you bleed the brakes?

Customer: replied 10 months ago.
sitting in the drivers seat facing forward, right rear, left front, left rear, right front
Yes one person opening the bleeder valve one person pumping the brake pedal.
pump the brake pedal hold, open the bleeder valve pedal goes to floor hold close bleeder valve repeat 3 times no bubbles clear flow close valve and move on to next wheel.

The drivers side is considered the Left Side. Passenger side is considered the Right..

Customer: replied 10 months ago.
No foolin
Expert:  Jay replied 10 months ago.

Do you have the bleeders pointing up on the rear calipers?

Expert:  Jay replied 10 months ago.

Just making sure you know which side is right and which side is left.

Expert:  Jay replied 10 months ago.

When you are bleeding each wheel, how many times are you bleeding each wheel at a time around?

Customer: replied 10 months ago.
Bleeder on rear calipers are at: right rear 3 o'clock, left rear 9 o'clock
We bleed each wheel 3 to 5 times each go around and we have done the cycle 4 times now.
Customer: replied 10 months ago.
We keep the reservoir full, never goes below midway, never gets to the low level
Expert:  Jay replied 10 months ago.

It sounds like the r/r should be at 2 oclock and l/r should be at 10

The bleeders should not be directly pointing straight out, they should be up slightly...

Expert:  Jay replied 10 months ago.

This way the air pocket can be released. If they are pointing in the directions you told me, then you may have the wrong calipers.

Customer: replied 10 months ago.
How will we know we have the wrong calipers?
Bought them from NAPA
Fit perfectly but the bleeders protrude almost perfectly parallel to the ground
Customer: replied 10 months ago.
right front is at 2 o'clock and left front at 10 o'clock
Bought new rotors also, maybe can move the rotors up one lug and that would put the bleeders at 2 o'clock and 10 o'clock I think
Expert:  Jay replied 10 months ago.

? Sorry?

Customer: replied 10 months ago.
Calipers looked just like the old ones compared them before we took them.
Expert:  Jay replied 10 months ago.

Ok.. When you are bleeding the brakes.. You have on guy pumping the pedal, the holding it while you crack the bleeder right. Then you close the bleeder and he releases the pedal right? then pumps again?

The system should bleed. It sounds like you have everything right and the order is right. Just wondering, cause this could explain some things.

Did you miss bleed this once by mistake, then found the order and tried bleeding again?

Customer: replied 10 months ago.
to all of the above. Bled this way from the start read the infiniti manual to make sure we had the correct order.
Expert:  Jay replied 10 months ago.

The only thing I can think of is something is wrong with the calipers you brought if you can't bleed the system.

You are doing everything right. Is this a coupe or sedan?

Customer: replied 10 months ago.
Coupe
Expert:  Jay replied 10 months ago.

Maybe they gave you sedan calipers and that is why it's not bleeding.

Passenger rear, Drivers Front, Drivers Rear, Passenger Front.

Make sure you have the Key off also, you can't bleed it with the key ON

Customer: replied 10 months ago.
We had key off and battery disconnected.
Maybe will take the calipers back and get new ones to see if that makes a difference.
Expert:  Jay replied 10 months ago.

Yea, That is what I would do..

Customer: replied 10 months ago.
OK we'll try that and see if we get better results
Thanks
Expert:  Jay replied 10 months ago.

Your welcome.. Please return back and let me know how you make out.
