Somebody who knew once, said about brake shudder:

"In more than 40 years of professional racing, including the Shelby/Ford GT 40s – one of the most intense brake development program in history I have never seen a warped brake disc.
To induce that kind of permanent deformation, you would need to heat your rotors to a sustained temperature of over 738 degC then rapidly quench them in order to convert the thermoelastic instability generated hot spots to martensite instead of the ferritc/pearlitic matrix you started with.

Your basic brake pads will begin fading around 350 degC. Your high performance pads will begin fading around 550 degC. You will start to break down the surface of your rotor into cementite hard spots around 610 degC.

Your basic Dot III brake fluid will begin to boil as low as 140degC. High performance brake fluid will only take you to around 300 degC.

Bottom line - Your brakes will fade into near uselessness long before you can achieve the conditions necessary to warp your rotors.

Uneven deposition of friction material results in this thickness variation or run-out due to hot spotting that occurred at elevated temperatures."
