Peter is hitting closer to what's going on. If there was a 
problem with the rotors/pads, you should feel it back 
through the master cylinder (i.e. the lever).

A common cause of brake shudder is poor suspension setup. 
Induced by too little compression damping and/or too much 
rebound damping. Uneven pavement in corner entrances along 
with poor suspension can induce a "pogo'-ing effect under 
hard braking often mistaken for brake problems. A loose 
head stem/bearing can also induce an oscillating effect 
commonly labeled brake shudder. Check both areas out.
