How do you remove the piston from a CL16 front brake caliper?

Remove the brake hose, then push out the piston with the dust seal using compressed air.

What should be used to clean CL16 caliper parts during inspection?

Use brake fluid to clean. Never use mineral oil.

Can you polish the caliper piston with emery paper?

No. The piston sliding surface is plated, so do not polish with emery paper even if rust or foreign matter is stuck to the sliding surface.

What do you check the cylinder body for, and when should it be replaced?

Check the inside surface for score, rust, wear, damage, or foreign materials; replace the cylinder body if any are observed. Minor rust or foreign material damage may be removed by polishing with fine emery paper, replacing the cylinder assembly if necessary.

What are the key points when assembling the CL16 caliper piston?

With the dust seal fitted to the piston, insert the dust seal into the groove on the cylinder body and install the piston; properly secure the dust seal and pay attention to the direction of the piston seal.

This is page BR-10 from a Nissan factory service manual covering the front disc brake caliper, type CL16. The page details three procedures: Disassembly, Assembly, and Inspection. For disassembly, the brake hose is removed and the piston with dust seal is pushed out using compressed air, shown in illustration SBR772. For assembly, the dust seal is fitted to the piston and inserted into the groove on the cylinder body before installing the piston; the reader is instructed to properly secure the dust seal and pay attention to the direction of the piston seal, with a cross-section diagram (SBR574) labeling the dust seal, piston seal, piston, and cylinder body. The Inspection section warns to clean parts only with brake fluid, never mineral oil. It instructs checking the cylinder body's inner surface for score, rust, wear, damage, or foreign material, replacing it if found, though minor rust damage may be removed with fine emery paper. The piston should be checked for the same conditions and replaced if any are observed; a caution notes the piston's plated sliding surface must never be polished with emery paper. Guide pins, lock pins, and boots should be checked for wear, cracks, or damage and replaced as needed.
