## Master Cylinder Reassembly

NOTE:

- If replacing the primary piston, secondary piston, or master cylinder body, check and adjust the pushrod clearance before installing the master cylinder.
- Clean all the parts in brake fluid and air dry; blow out all passages with compressed air.
- Before reassembling, check that all the parts are free of dust and other foreign particles.
- Replace parts with new ones whenever specified to do so.
- Use only genuine DOT3 Honda brake fluid. Non-Honda brake fluid can cause corrosion and shorten the life of the system.
- Do not mix different brands of brake fluid as they may no be compatible.
- Replace the master cylinder if the bore is damaged or worn. Do not hone or attempt to refinish the bore.
- Coat the piston cups, pressure cup and master cylinder bore with clean brake fluid.
- Use recommended greases in the master cylinder seal set.
