Dust Seal Assembly Note

1. While rotating the piston counterclockwise using the SST

, pull it out to the position shown in the figure.

2. As shown in the figure, assemble a new dust seal to the piston.

3. Install the SST

(49 F043 002) to the SST

(49 B043 005).

4. Align the SST

projection to the piston groove.

5. Rotate part A on the SST

in the direction of the arrow and secure the SST

to the caliper.

6. Rotate the SST

(49 B043 005) in the direction of the arrow and push the piston completely into the caliper.

NOTE:

• Even with the piston completely pushed in, the top of the piston projects from the dust seal by approximately 2 mm

  {0.09 in}

  .

7. Rotate part A on the SST

(49 B043 005) in the direction of the arrow using the tool and remove the SST

from the caliper.

8. Assemble the dust seal to the caliper body using the SSTs

and a press with a press-in force of 834 N {85 kgf, 187 lbf}

.

9. Verify that there is no gap between the dust seal and caliper body.
