- With the engine off, depress the brake pedal fully several times to evacuate
the vacuum in the booster.
- Once all the vacuum assist has been eliminated, press the brake pedal down
by hand and confirm that the amount of movement before resistance is felt
is within 0.16–0.28 in. (4–7mm).
- If the free-play is less than desired, confirm that the brake light switch
is in proper adjustment.
- If there is excessive free-play, look for wear or play in the clevis pin
and brake pedal arm. Replace worn parts as required and recheck brake pedal
free-play.
