NOTE:
Adjust clearance between booster piston rod and mas-
ter cylinder piston. (Refer to “INSPECTION AND
ADJUSTEMENT” of “BRAKE BOOSTER”.)
Check length of push rod clevis.

INSPECTION AND ADJUSTMENT
Installation Position Of Push Rod
If push rod clevis (1) has been removed, adjust distance between
booster installation surface (without including packing) and the
center of clevis pin hole to standard value “a” and tighten nut (2)
to specified torque.
Distance “a” between center of booster clevis pin hole
and booster surface
Standard : 97 - 98 mm (3.82 - 3.86 in.)
Tightening torque
Clevis pin lock nut (a) : 19 N·m (1.9 kg-m, 14.0 lb-ft)
Clearance Between Booster Piston Rod And Master Cylin-
der Piston
The length of booster piston rod (1) is adjusted to provide speci-
fied clearance “a” between piston rod (1) end and master cylinder
piston (2).
Before measuring clearance, push piston rod several times
so as to make sure reaction disc is in place.
Keep inside of booster at atmospheric pressure for measure-
ment.
Measure length “a” of piston rod, i.e. distance between piston rod
and mating surface of booster-to-master cylinder.
Length “a” of piston rod
: 30.3 - 30.5 mm (1.193 - 1.200 in.)
If measurement is out of specification, adjust piston rod by turning
adjusting screw of piston rod.
Special tool
(B) : 09952-16020
NOTE:
Remove gasket from booster, if equipped.
