The caliper looks like it is compressing correctly could there still be a issue with it?I have kinda the same problem. Mine is a grinding/rubbing. Sounds like it is coming from the passenger side wheel . I have replaced:
Driver side:
Wheel Hub
Wheel Bearing
Ball Joint
Brakes
Cv Axle
Passenger Side:
Cv Axle
Control Arm
Brakes
I replaced all this and still have not figured out what is making the sound.
