LMAO yea I find it funny when I read comment like this.
Most common is, "rotor warpage". It is near impossible to cause any fluctuation in a rotor. To come even close you'd have to travel at F1 or NASCAR speeds to get them glowing hot, then stop. Leaving the brakes on to let the pads bake into the metal.

Warped rotors are very common in Europe

Getting brakes glowing hot is unfortunately easy, no need for F1 speeds, a mountain and a lot of hairpins will do. Even start and stop traffic downhill or emergency stop on the autobahn can warp your rotors. It is worse there is water on the road.

Some rotors are warped when new, even good brands, I always check them first.

One thing to check before replacing the rotors is the surface of the hub, even a little dirt can get the rotors out of alignment.

-Warped- Brake Disc and Other Myths

Excerpt from link:
"...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."
