Vacuum Booster: Notes
CAUTION:
- When removing the master cylinder from the vacuum booster, be sure to get rid of the internal negative pressure of the vacuum booster (by, disconnecting the vacuum hose) in advance. If any negative pressure remains in the vacuum booster, the piston may possibly come out when the master cylinder is being removed, letting the brake fluid run out.
- DO NOT hold the piston while removing the master cylinder, the piston can be easily pulled out. Outside surface of the piston is the surface on which seals are to slide. Care should be taken to keep the surface free of cuts and dents.
NOTE:
The vacuum booster is not repairable and must be replaced as a complete assembly.
