Piston Disassembly Note

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

The piston could be damaged if it is blown out with great force. Blow compressed air slowly to prevent the piston from suddenly popping out.

Place a piece of wood in the caliper, then blow compressed air through the hole to force the piston out of the caliper.
