Removal
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, for instance, 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.
While removing the 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.
1. Disconnect electrical connector.
2. Remove brake pipes and after disconnecting the
brake pipe, cap or tape the openings of the brake
pipe to prevent the entry of foreign matter.
3. Remove 2 attaching nuts.
4. Remove P&B valve and bracket.
5. Remove master cylinder.
6. Remove spacer and the 2 gaskets.
