It originally went 1/2 way but when we tightened the wheel bearings, it did get a little better. The harder I turn the wheel or hang an exit ramp, the more pronounced the pedal drops is. Do you have any extra slop after a hard turn? Using KH style setup?
What AJ is suggesting (and it's a good point) if the cup weren't driven fully hard against it's seat it could shift slightly allowing additional bearing play...
Might be a good ideal to pull the rotors & check if the cups are fully hard against their seats..
