b. Push in the pedal by hand until the second point of resistance begins to be felt, then measure the distance, as shown.
Pedal freeplay: 1 - 6 mm (0.04 - 0.24 inch)
If incorrect, check the stop light switch clearance. If the clearance is OK, then troubleshoot the brake system.
HINT: The freeplay to the 1st point of resistance is due to the play between the clevis and pin. It is 1 - 3 mm (0.04 - 0.12 inch) on the pedal.
