  3. 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.
  4. 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.
