Adjust the push rod clearance as follows. (1) Attach the SST to the power brake unit as shown in the figure, and tighten the locknuts to the specified torque (Tightening torque: 9.9–15.6 N·m {100–160 kgf·cm, 86.8–138 in·lbf}). (2) Apply 66.7 kPa {500 mmHg, 19.7 inHg} vacuum by using a vacuum pump. (3) Measure the depth L of the gauge rod (Depth: 35.3–35.5 mm {1.390–1.397 in}). (4) If it is not specified, use the SSTs to adjust the push rod to the proper length. (5) Verify depth L of the gauge rod.
