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