- Turn the nut of the SST
clockwise to fully retract the SST
gauge rod. Attach the SST

Tightening torque
- 9.8-16 N.m {1.0-1.6 kgf.m, 7.3-11 ft.lbf}
- Apply a 66.7 kPa {500 mmHg, 19.7 inHg} vacuum by using a vacuum pump.
- Turn the adjusting nut of the SST counterclockwise until the gauge rod just contacts the push rod end of the power brake unit. Push lightly on the end of the gauge rod to be sure it is seated. Verify that there is no gap between the adjusting nut and SST body.
- Remove the SST
from the power brake unit without disturbing the adjusting nut. Set the SST
onto the master cylinder as shown in Fig 2.CAUTION:
- When pushing the SST gauge rod into the master cylinder piston, only use enough pressure to push the rod to the bottom of the piston. If too much pressure is applied, a false reading will occur.
