Unhappy AU XR6 - rotational noise or squeak after new brakes

Hi Guys, have a very annoying problem appeared recently which has a few mechanics scratching their heads -(
Pads and Rotors changed, all checked by same outfit and mechanic that has serviced the car for the last 4 years no problems... now we have a type of squeak that can realy only be heard if running at 100km's along the motorway against a barrier to get the sound to bounce back at you. It would sound like it's coming from the R/F wheel or brake assembly, the noise stops when applying the brakes... (have checked handbrake - no difference) we have since gone through 2 more sets of rotors and pads, new calipers etc, coils and shocks checked... driving us NUTS !! please help..

Default squeak

Hi guys,

This squeak can sometimes come from the contact between the pad and the caliper. There sometimes is a bit of movemnet which makes it squeak. When you apply the brakes the movement is stopped by the pressure of the piston.

There is a CRC product called "Disc Brake Quiet" which you apply to the back of the pads to eliminate this. Check out the link below for details..
