Rear Disc Brake Caliper: Reassembly

1. Assemble caliper in reverse order of disassembly. Use new piston and dust seals. Three kinds of grease contained in seal kit must be used. Use White grease on the "O" ring. Apply Red grease on piston seal.
2. Apply Orange grease on guide pins, boots, dust seal, adjuster spindle, connecting link and spindle lever. Reverse disassembly procedures. Align stopper pins with holes of caliper housing.
3. Install piston using Brake Piston Wrench (49 FA18 602). Turn piston clockwise until piston is fully seated in caliper. Position piston after seating to ensure that dowel on brake pad fits in piston stopper groove.

Apply clean brake fluid to cylinder bore, piston and piston seal. Seat piston seal in caliper bore. Install piston carefully into cylinder bore. Install dust boot and retainer.
