1. Install the SST
to the power brake unit as shown, and tighten within the specified torque.
Tightening torque 9.8-16.0 N·m {100-163 kgf·cm, 87-141 in·lbf}
2. Using a vacuum gauge, create a vacuum pressure of 66.7 kPa {500 mmHg, 19.7 inHg}
in the power brake unit.
3. Using calipers, measure dimension L as shown.
Specification

4. If dimension L is not within the specification as shown, remove SST
(49 E043 001) and use SST
(49 B043 004) to adjust the length of the push rod while using SST
(E043 003A) to keep the push rod from rotating.
5. Remove the SSTs
