Models Without VDC: Assembly

WARNING: This page is about a different car, the 2005 Nissan 350Z. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • Never use mineral oils such as kerosene, gasoline during the cleaning and assembly process.
  • Make sure there is no foreign matter such as dirt or dust attached to the inner cylinder walls, the piston, or the cap seal, and use care to avoid damaging parts with the assembly tools.
  • Do not drop parts. If a part is dropped, do not use it.
  1. Apply fluid to cylinder inner wall body and contact surface of the piston assembly. Then insert secondary piston assembly and primary piston assembly into cylinder body in this order.
    CAUTION:
    • Do not reuse the primary and secondary piston assemblies.
    • Be sure to replace the assembly without disassembling the new inner kit.
    • Pay attention to the orientation of the piston cup, and insert straight to prevent the cup from being caught by cylinder inner wall.
