Hello community. :inout:
Please someone explain me why Titan brake bleeding documentation states this order
1 Rear Right, 2 Front Left, 3 Rear Left, 4 Front Right.
My Titan ABS actuator (1) it is on left side near the master cylinder and the connector (4)
near the rear axle.

ABS actuators with a dual diagonal internal setup (not all are arranged that way) always use a criss-cross pattern, such that you're bleeding each half of the diagonal individually with the longer leg of each half being bled first.

Well, now I'm a bit puzzled myself. I just pulled up the '05 hydraulic diagram and that says the rears aren't individual. So I don't get the bleeding sequence either, conventional wisdom says that for shared lines you bleed them longest to shortest. So why the engineers specified a dual diagonal bleed pattern is a mystery.

I went to bleed with the ABS disconnected this way...
1 Rear Right, 2 Front Left, 3 Rear Left, 4 Front Right.
Numerous times, the pedal it is still not the best a little low, it improves on second and third depress.
1 Rear Right, 2 Rear Left, 3 Front Right, 4 Front Left makes more sense?

I would think so, yes.

Thank you sir.
Nissan should hire you to proofread and correct some of their none senses.

I just read this check point

1. Make sure your wheel bearings are tight and there's no wobble. if the hub wobbles, the rotor presses the pads outwards. initial brake press re-centers the rotor.
Second brake press does actual braking.

I have the axle play of .032 in with new bearings/seal and the brake pedal low after numerous bleedings, it improves on second and third depress.
I'm connecting the wrong dots?

No, those are legit dots, that could certainly contribute to your brake issue. Wobble isn't as serious an issue on a live axle as on an independent one because the angle change from a bad bearing is less, but end play will cause the same issue for a different reason, in-out movement every time the bearing loads and unloads. The result is the same, the pads get backed off further from the rotor than they should.

Thanks for all the suggestion and comments. I really appreciate it. All my respect.
I'm taking in consideration to take out the axle again, check for straightness as suggested earlier, bearing and seals are new eventually add a .020-.025 shim ( if i found one) before i focus on power booster or MC. I did lots of brake system bleeding in hopes to improve braking performance, i hope did not damage any MC or booster seal. I'm not sure if this is the right approach to solve this performance issue. My truck brake piping it looks like in the picture below.

A friend might deal with the spongy brake in this new '05 Titan project. He ordered new nittos and xd wheels and looking to get the brake job done at the same time. Any tip would be appreciated.
