Problem: Heavy shudder upon braking

[Big T]

This is on my ‘99 Suburban. Have a shudder from the right front upon braking. It increases the heavier I hit the brakes.

This was happening before the broken tie rod incident which was on the right front. I rebuilt the front end with new ball joints, tie rods, ES poly bushings on forged replacement LCAs. It passes the dry park test with no play on the tie rods in the knuckles. Ball joints are tight. It drives smooth and tight at highway speed, but this brake shudder persists.

Today I replaced rotors, pads (close to wear bars) and calipers, but the shudder persists. I am now at a loss as to what is causing this, so I’m reaching out for help.

Only thing I know can cause that is warped rotor.
Jack it up, remove front tire/wheel.
Hold a center punch real close to rotor and turn the rotor.
See if the punch drags on the rotor.
Could maybe also be created from an out of round rear braking drum.

Old rotors did it and brand new rotors are doing it. Do not feel it in the pedal nor at stops at slow speed.
