Rear Disc Brake Caliper (RX7): 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.
2. Use White grease on caliper slide and mounting bolts. Use Orange grease on bearings, adjusting bolt, strut and piston boot. Use Pink grease on piston seal.
3. Lubricate piston and caliper bore with clean brake fluid. Press in needle roller bearing so that arrow on bearing faces outward.
4. Assemble conical spring and adjusting bolt. See Fig 1 . Install adjusting bolt assembly, strut and torsion spring in caliper.
5. Install piston using Disc 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.
