I have a pretty significant steering wheel shutter/shake when I am braking within the range of 100km/h-85km/h- but ONLY within this range, haven't been able to replicate it otherwise.

I had the rotors replaced 20,000km ago but had the brake install re-examine the job and even warranty replace the rotors but the shake still exists.

What could be causing this?

FCABS? If so, is a press absolute required to replace them or can it be done by hand with enough force ?
