Special tools are required for this procedure.

  1. Remove the caliper.
  2.  
  3. Place the caliper in a soft-jawed vise.
  4.  
  5. Remove the dust cover.
  6.  
  7. A tool can be made to unscrew the piston. Follow the accompanying illustration in making this tool.
  8.  
  9. Install the tool and unscrew the piston. When it turns freely, remove the tool and apply compressed air at the brake line port. Put a soft cloth in front of the piston. Never try catching the piston with your fingers. Crunched fingers would result.

  12.  
  13. Remove the piston seal. Discard it.
  14.

  17. Installation is the reverse of removal. Coat all parts with clean brake fluid prior to installation. Use your homemade tool to finish installing the piston. Always use a new piston seal and dust cover.
