Brake Pedal Height, Free Play & Stoplight Switch
NOTE:
Push rod serves as brake pedal stopper when brake pedal is fully released. Pedal free play is measured with engine off and brake pedal depressed 5 times to release power brake unit power assist.
- With brake pedal fully returned, measure pedal height from upper foot rest portion of pedal pad to floor board. See Fig 1 . Pedal height should be 8.2-8.6" (208-218 mm).
- To adjust pedal height, disconnect negative battery cable. Unplug stoplight switch connector. Loosen stoplight switch to ensure brake pedal is fully returned. Loosen push rod lock nut. Rotate push rod to obtain specified pedal height. Check pedal free play. See Fig 1 . Pedal free play should be .2-.4" (6-10 mm).
- Check depressed pedal height. Depressed pedal height, with 110 lbs. (50 kg) stepping force applied, should be more than 2.2" (55 mm).
- Install and adjust stoplight switch clearance "A" between stoplight switch housing (not actuating pin) and brake pedal tab to .02-.04" (.5-1.0 mm). See Fig 1 . Tighten stoplight switch lock nut. Reconnect stoplight switch connector and negative battery cable.
