08FOO27. ADJUSTMENT OF CLEARANCE BETWEEN CLUTCH
BOOSTER PUSH ROD AND PISTON
Adjust the clearance (A) between the clutch booster push
rod and piston as follows:
(1) Measure the dimension
(B) between the master cylin-
der end face and piston.
NOTETo obtain
(B), first take measurement with a square
placed on the master cylinder end’ face. Then, subtract
the thickness of the square to arrive at (B).
(2) Obtain the dimension
(C) between the clutch booster
mounting surface on the master cylinder and the end
face.(3) Measure the dimension
(D) between the master cylin-
der mounting surface on. clutch booster and the push
rod end.
NOTETo obtain
(D). first take measurement with a square
placed on the clutch booster. Then, subtract the
thickness of the square to arrive at
(D).
(4) Using the measured values obtained in (1) through (3).obtain the clearance (A) between the clutch booster
push rod and piston.
Standard value: [A (A = B
- C - D )]
0.2j - 0.46 mm (.0082 - .0181 in.)
[Atmospheric pressure][When the clutch booster negative pressure of 66.7
kPa(9.7 psi) is applied, the clearance (A) becomes 0.1 to 0.3
mm
(.0039 to .0118 in.).]
(5) If the clearance is not within the standard value range,
adjust by changing the push rod length by turning the
adjustable end of the push rod.
CautionImproper clearance may cause excessive brake
drag.JTSB Revision

(1) Remove the corrosion from the piston-removal port of
the release cylinder.
(2) Remove the piston from the release cylinder using
compressed air.
Caution1. Cover with rags to prevent the piston from
popping out.
2. Apply compressed air slowly to prevent brake
fluid from splashing.
