Rear brake squeal

[Ricky]

Hi all.

I have a 2012 Insignia hatch 2.0 diesel and its driving me insane. I have replaced the brake pads, disc, bracket, caliper, bled the system and even replaced the bearing but I still have a squeal wheel driving between 30mph and 60mph. It's on the rear right wheel.

Any advice on what it could be and how to fix it?

Thanks

Have you applied copperslip on the pads where they slide back and forwards in the carrier?
if not, then the pads could be stuck and slightly contacting the disc rather than retracting away from the disk

Would need to pop the pads out and coat the contact parts (metal to metal contact only)
