WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

If the piston is pushed into the rear brake caliper while rotating the piston, the rear brake caliper internal parts and dust seal could be damaged. Be careful not to rotate the piston when pushing the piston into the rear brake caliper.

Completely press in the piston using a commercially available disc brake expander tool.
