Extreme Intermittent Brake Shudder

2002 Excursion 7.3
205,000 Miles

On two different occasions, I have experienced a rather violent shaking or shuddering under braking. On both occasions, I have been driving at sustained highway speeds for 30 minutes or longer. When applying the brakes I got a violent shuddering in the whole truck. There was no pedal pulsation and no steering wheel vibration. After arriving at my destination and the vehicle sitting for a period of time, I traveled home the exact same route and the shudder didn't happen on the trip home.

The following repairs have been made since I purchased it:

International Bellowed Up Pipes and Collector
EXBPV Deleted Turbo Pedestal
EXBPV Deleted Turbo Outlet
MBRP Exhaust
EBC Slotted/Dimpled Rotors and Orange Stuff Brake Pads
Rear Calipers
Hub Assemblies
Axle Shaft Seals
Half Shaft U-Joints
Stainless Brake Lines from Master Cylinder to ABS Module and from ABS Module to all wheels
New Rubber Brake Lines at all wheels

Again, this is a violent shudder and it seems to be an up and down shudder, not side to side or front to back. It is nothing like warped rotors feel at all.

Tires are in good condition and wheels are balanced.

Any ideas about what may be causing this?

I haven't replaced the shocks, and I am sure that they are overdue...

My guess is that when this shudder was to occur, you will find that one front rotor is smoking hot. Then you should replace the caliper and flexible hose at that wheel.

FYI....mine does it too....but I'm waiting it out for my new project truck to be finished.

edit...I see you have new lines.

I bought new lines rotors and calipers multiple times. What ended my issues were buying the upgraded slide pins for the front calipers.
