Master Cylinder Pushrod Clearance Adiustment (cont'd)
5, With a feeler gauge {A), measure the clearance
between the gauge body and the adjusting nut (B)
as shown.
lf the clearance between the gauge body and the
adjusting nut is 0.4 mm (0.02 in.), the pushrod-to-
piston clearance is 0 mm. However, if the clearance
between the gauge body and the adjusting nut is
0 mm, the push rod-to-piston clearance is 0 4 mm
(0.02 in.) or more. Therefore. it must be adjusted
and rechecked.
Clearance: 0 0.4 mm (0 0.02 in.l
lf the clearance is incorrect, loosen the star locknut
(A), and turn the adjuster (B) in or out to adjust.
. Adjust the clearance while the specified vacuum
is applied to the booster.
. Hold the clevis (C) while adiusting.
