Brake Pedal Freeplay
CHECK PEDAL FREEPLAY
a. Stop the engine and depress the brake pedal several times until there is no more vacuum left in the booster.
b. Push in the pedal by hand until the resistance begins to be felt, then measure the distance.
Pedal freeplay: 1 - 6 mm (0.04 - 0.24 inch)
HINT: The freeplay to the 1st resistance is due to the play between the clevis and pin. This is magnified up to 1 - 6 mm (0.04 - 0.24 inch) at the pedal. If incorrect, check the stop light switch clearance. If the clearance is OK, then troubleshoot the brake system.
Stop light switch clearance: 0.5 - 2.4 mm (0.020 - 0.094 inch)
