At this point I’ll try anything, I’ve searched and started threads asking about power steering whining and better braking and got nothing but a bunch of charts and graphs and people saying it is what it is. That truck stops ten times better than my Excursion and yes, everything is done correctly. My steering is fine but as Jack mentioned at low speeds there’s a lot of power steering pump whining and the brakes just don’t stop that heavy rig as well as I thought they would with all the upgrades I did. It’s not a stock truck so I don’t want to hear about Motorcraft pads and rotors should stop it on a dime or that I didn’t bleed the brakes right or the fluid is wrong. I want to hear my tires bark like in the video when he stops at the very end.

well did my flush today . sorry no video . started with back flushing the oil cooler ,then the heater core . the tool did work , got some debris out of the
oil cooler . flushed with just tap water and about 25 psi of air .then blew out both the oil cooler and heater core with just air . then flushed the system with
tap water for awhile ,then flushed with about 25 gal. of distilled water. refilled system with rotella elc ec-1 rated concentrated coolant and distilled water.
deltas were pretty good at idle then peaked at 12 going 70mph and 90 degrees out , I am hoping it just needs bled some more .

How did you flush it? Did you remove both or at least one block drain too? I got about a half cup of casting sand out of mine when I flushed it and most came from the block drain hose, not the lower radiator hose. Deltas were 3-4 degrees after.

Anyway, yeah, another chart, thumbnail calculator version. I may have done similar before, there are several ways. Rolling radius leverage over rotor radius. You either up the pedal effort, alter the clamping pressure (Caliper piston size) or change the friction material unless you want to do as we did in the OE designs - more weight capacity or larger tire = larger rotor diameter. And that's not easy or cheap. The downside, most higher friction materials move the friction bell curve higher, and with an unladen truck that hasn't gotten much heat into the friction and rotor, the friction may be the same or lower coefficient than standard duty friction material.
The '05 design got larger rotor 0.2" slightly larger calipers, and about half that friction material increase so it could handle the new GVW and tire sizes. No change in thermal ability and actually ran hotter than '99 design level with a higher bias towards the front brakes (less rear axle skid prone empty). The friction moved to 0.35.

and the whine was gone and even the DD truck does not whine any more. The one thing I did do was a vacuum bleed after filling thereservoir on both trucks.
Both are quiet.

Also both block drains do need to be removed.
SrMasterTech has some good videos on flushing.

unfortunately I was unable to remove the block plugs , they were seized in the block and started to
strip out . so I removed the radiator drain plug and just ran tap water through the degas bottle for awhile
with engine running. then flushed with about 25 gallons of distilled water.
