Caution

•  Brake fluid will damage painted surfaces. Be careful not to spill any on painted surfaces. In addition, if there is any brake fluid on the wiring harness, the wire insulation may corrode causing a malfunction such as a short circuit. If brake fluid gets on a painted surface or wiring harness, wash and flush it off completely with water immediately.

1.  Remove in the order indicated in the table.

Piston Disassembly Note

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.

1.  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.

Caution

•  If the piston is pushed into the caliper while rotating the piston, the caliper internal parts could be damaged. Be careful not to rotate the piston when pushing the piston into the caliper.

3.  Align the head of the spindle nut with the inner shape of the piston and press the piston into the caliper body completely.

4.  Verify that the dust seal is installed into the caliper body groove.

5.  Verify that the piston grooves are at the positions shown in the figure.
