New rotors and pads on rear about 1 year ago. Also replaced parking brake shoes and hardware. No noises until now. Rhythmic squeal from right rear that stops when brakes are applied.

Removed caliper, pads. Cleaned rotor and removed all dust and debris from inside back of rotor and surrounding areas. Cleaned and re-lubed all caliper slide points and pins.. Cleaned and applied Disk Brake Quiet to metal contact points on pads. Re-assembled all to specs. Squeal persists when brakes heat up and stops when brakes are applied.

What to check for now? Wear indicator tab may have gotten bent during handling? Re-adjust parking brake to allow more room? Other considerations?

Did you look at the warning sensors to see if they could be making contact with the rotor anywhere?

Removed caliper. The warning sensor seemed to be bent, almost touching rotor. I bent it away from rotor and will determine if that resolves issue when brakes heat up. I'm optimistic that was the source of the squeal. Thanks.
