CLEARANCE BETWEEN BOOSTER PISTON ROD AND
MASTER CYLINDER PISTON CHECK AND ADJUSTMENT
The length of booster piston rod (1) is adjusted to provide speci-
fied clearance “0” between piston rod (1) end and master cylinder
piston (2).
1) Before measuring clearance, push piston rod several times
so as to make sure reaction disc is in place.
2) Keep inside of booster at atmospheric pressure for measure-
ment.
3) Check depth of piston rod, i.e. distance between piston rod
and mating surface of booster-to-master cylinder.
Depth “c” of piston rod for check :
15.8 – 16.6 mm (0.623 – 0.653 in.)
