Disassembly & Reassembly

1. Disassemble in the order indicated in the illustration. See Fig 1.
2. Assemble in the reverse order of disassembly. Tighten all fasteners to specification. See TORQUE SPECIFICATIONS .

Dust Seal Assembly Note

1. Assemble a new dust seal to the caliper using Piston Press Rod (49-G033-102) and Socket (49-B033-001) and a press with a press-in force of 187 inch lbs. See Fig 2.
2. Verify that there is no gap between the dust seal and caliper body.

Piston Assembly Note

1. Press the piston into the dust seal opening as shown in the illustration. See Fig 3, for following steps
2. Insert a piece of wood between the caliper body and the piston, and while supporting the piston by hand, blow compressed air through the brake hose installation hole.
   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 into the caliper body, the dust seal expands due to air pressure and covers the piston end.
3. Verify that the dust seal lip covers the piston end.
4. Press the piston into the caliper body completely.
