Sounds like your rotors may be warped. You might wanna take them off and have them turned down at a mechanic shop or possibly just buy new ones.

Either that or the cosmic rays are hitting the earths crust and causing small earthquakes at the exact moment you are pushing the brakes......Hey, it could happen!

And, in addition to a "hot spot" or "warp" on the rotor(s), which gives more of a pulsing linear "shake"...
IF
The shake has a side-to-side component, you may have a few worn/loose pieces in the front steering linkage.
But,
I'd do the rotors first.



ALTHO,.... I really like the "small earthquake" theory

It was the earth quaking in my case.
