REMOVAL
CAUTION:
When removing master cylinder from vacuum
booster, be sure to get rid of the internal negative
pressure of the vacuum booster (by, for instance,
disconnecting 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.
While removing master cylinder, further, do not hold
the piston as it 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.
