(a) Stop the engine. Depress the pedal several times until there is no vacuum in the booster. Then release the pedal.

(b) Depress the pedal until resistance is felt.

(c) Check the pedal's free play by measuring the distance between the position in the previous step and the pedal's released position.

Standard pedal free play:

1.0 to 6.0 mm (0.0394 to 0.236 in.)

If the free play is not as specified, check the switch clearance in the next step.

If the free play is as specified, proceed to the "check brake pedal reserve distance" procedure.

(d) Check the switch clearance.

Standard stop light switch clearance:

0.5 to 2.6 mm (0.0197 to 0.102 in.)

If the clearance is not as specified, adjust the clearance and recheck the pedal's free play.

If the clearance is as specified, troubleshoot the brake system and proceed to the "check brake pedal reserve distance" procedure.
