With master cylinder removed from vehicle, as described under COMPONENT REPLACEMENT AND REPAIR PROCEDURES/MASTER
CYLINDER, proceed as follows:
a. Measure distance between master cylinder end face and the piston, Fig. 7. Position a square (straight scale) against edge of master cylinder,
then measure and subtract thickness of the square to determine dimension B.
b. Find dimension C by measuring distance between brake booster mounting surface and the end face, Fig. 8.
c. Measure distance between master cylinder mounting surface and the pushrod end, Fig. 9. Find dimension D by subtracting the square's
thickness from the measurement taken.
d. Find brake booster-to-primary piston clearance dimension A, Fig. 10, using the formula A = B - C - D. Refer to Fig. 11, for proper clearance
specifications.
e. If dimension A is not as specified, adjust brake booster pushrod as shown Fig. 12.
