CLEARANCE BETWEEN BOOSTER PISTON ROD AND
MASTER CYLINDER 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 "b" of piston rod, i.e. distance between piston rod
and mating surface of booster-to-master cylinder.
Length "b" of piston rod
30.3 – 30.5 mm (1.193 – 1.200 in.)
NOTE:
Remove gasket from booster, if equipped.
If measurement is out of specification, adjust piston rod by turning
adjusting screw of piston rod.
