Pad Knockback Issue

[stab6902]

Do you think the movement of the rotor is mostly axle thrust play or axle bending moment from vertical and horizontal forces (mainly cornering)?

If the amount of knockback gets proportionally worse as you corner harder, I'd guess mostly bending. If it happens even during easy street driving, I'd guess mostly axle play. I'm assuming end play etc feels/measures tight with the car on jack stands?
