Piston Disassembly Note
WARNING: This page is about a different car, the 2021 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
- When compressed air is blown into the caliper body, injury to a finger or other part from pinching could result from the piston springing up. When blowing in compressed air, do not place your fingers between the piston and caliper body when performing the work.
CAUTION:
- The piston could be damaged if blown out with great force. Blow the compressed air slowly to prevent the piston from suddenly popping out.
- Insert a piece of wood in the caliper as shown in the figure and blow compressed air through the hole to remove the piston from the caliper body.
