Installation Notes and Precautions
•
Check the length and diameter of the push rod
from the pedal or power booster. It should fully
engage the bottom of the recess in the master
cylinder piston assembly without interference
along the sides or shoulders. For short push
rod power brake boosters, use the spacer
supplied to reduce the overall depth of the
piston recess. The piston detail diagram on
page 2 illustrates the overall depth and
diameter of the push-rod recess.
•
When the pedal is released, the piston
assembly must fully return to the snap-ring
retainer at the end of the cylinder bore.
Consequently, the push rod must be long
enough to remain captured inside the piston
recess when the pedal is fully retracted. Adjust
the length of the push rod and available pedal
travel as necessary. Return springs and pedal
stops are always recommended.
