Brake pedal travel — check (Chevrolet Trailblazer 1)

1. The brake pedal does not need to be adjusted, but the stroke should be checked when it is lowered. To do this you will need a ruler or tape measure.

2. Press the pedal several times to exhaust the vacuum booster potential.

3. Determine the pedal height in the free position. You can measure the distance from the pedal to the floor or from the pedal to the steering column. Write down the results obtained.

4. Press the brake pedal (apply a force of approximately 45 kgf) and determine the pedal stroke. Compare the obtained results with the values given in the specifications.

5. If the pedal travel exceeds the norm, examine the system for the presence of air in it (see subsection 8). Also, failure of the master cylinder seal may lead to an increase in pedal travel.
