With VDC Models: Assembly

WARNING: This page is about a different car, the 2007 Nissan Quest. 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.

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.
CAUTION:
- Pay attention to the orientation of the piston cups. Also, insert pistons squarely to prevent scratching the cylinder inner wall.
- Always replace the inner kit as an assembly.
