Other possible repairs:
Try carefully braking hard, repeatedly, and see if that clears the surface. Obviously, don't do it when there are any other cars anywhere around.
Also, there are non-woven nylon pads on a shaft (similar to 3M pads) that can be mounted in a drill and used to re-surface the rotors. Roto-loc?

Hi,
Just did some work on a Scion XA that had extreme brake shudder.
Took the front end apart and found black blotchyness on the rotors. Put it back together and did a series of heavy duty 70 MPH to 20 MPH slow downs. With each slow down the shudder was less and less. Finally it went away after about 7-8 repeats.
Cheap fix.
John
