2. Assemble in the reverse order of disassembly.

Piston Disassembly Note

  Caution
  • Blow the compressed air slowly to prevent the piston from suddenly popping out.

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

Dust Seal Assembly Note

1. Assemble a new dust seal to the caliper using the SSTs and a press with a press-in force of 834 N {85 kgf, 187 in·lbf}.

  Warning
  • When blowing compressed air into the caliper body, the piston may pop out and cause injury if not supported at the correct point. Securely support the piston friction surface by hand when blowing compressed air.

  Note
  • By blowing compressed air, the dust seal expands due to air pressure and covers the piston end.

3. Verify that the dust seal lip covers the piston end as shown in the figure.

4. Press the piston into the caliper body completely.
