4. Remove the piston seal from caliper body cylinder.





CAUTION: Do not damage the cylinder and piston seal groove.

5. Remove the lock pin sleeve and boot from caliper body.
6. Remove the guide pin boot.

ASSEMBLY
1. Clean the caliper body interior using brake fluid.
2. Apply a coat of brake fluid to the piston seal and fit piston seal in groove on caliper body.
3. Apply a coat of brake fluid to the entire inner surface of cylinder and outer surface of piston.
4. Apply a coat of specified grease to the boot and fit in to the groove on the ends of cylinder.
Grease: NIGLUBE RX-2 (Part No. K0779GA102)
5. Insert the piston into cylinder.

CAUTION: Do not force the piston into cylinder.





6. Position the boot in the grooves on cylinder and piston.
