Adjustment
Adjust the piston to push rod clearance in the follow-
ing order.
1. For (a) of judgement table
(1) Measure the height of (D) and record after
removing the SST from the master cylinder.
76G11X-028
Adjust nut
(2) Install the SST again to the master cylinder,
and turn the adjust nut so that clearance (C)
between the SST and the master cylinder is
0 mm (Oin).
(3) Measure the height of (E) when clearance (C)
is 0 mm (Oin).
(E) — (D) = Projecting amount of the power
brake unit push rod
76G11X-029
(4) Remove the push rod from the power brake
unit.
63G11X-349
(5) Make the piston to push rod clearance 0 mm
(Oin) by turning the push rod and shortening
the push rod length by the amount of (E) — (D).
Note
The threads of the push rod are specially
designed so that the push rod bolt becomes
harder to turn past a certain point to prevent
loosening of the bolt. Turn the push rod bolt
only within this range when adjusting.

2. For (b) of the judgement table
(1) Push the push rod of SST lightly by hand until
the push rod end touches the bottom of the pri-
mary piston in the master cylinder.
Note
When pushing only use enough pressure to
bottom the rod in the piston. If too much pres-
sure is applied a false reading will occur.
76G11X-031
(2) Measure clearance (B) between the adjust nut
and the SST body with the rod held down.
(B) = Recessed amount of the power brake
unit push rod
76G11X-032
(3) Remove the push rod from the power brake
unit.
63G11X-353
(4) Make the push rod clearance 0 mm (Oin) by
turning the push rod and lengthening the push
rod length by the amount of (B).
Note
The threads of the push rod are specially
designed so that the push rod bolt becomes
harder to turn past a certain point to prevent
loosening of the bolt. Turn the push rod bolt
only within this range when adjusting.
