6. Tighten the locknut D and the brake pedal installation nuts C. Service and Repair

7. Install the snap pin and clevis pin.

8. Turn the bolt B and adjust the clearance between the bolt B and the rubber.

Clearance
- 1.2-2.2 mm {0.048-0.086 in}

9. Tighten the bolt B with locknut A.

Tightening torque
- 10-14 Nm {102-142 kgf-cm, 89-123 in-lbf}

10. After adjustment, inspect the pedal play and the brake light operation.

Brake Pedal Play Inspection

1. Depress the pedal a few times to eliminate the vacuum in the system.

Brake pedal play
- 4-8 mm {0.2-0.3 in}

Pedal-to-floor Clearance Inspection

1. Start the engine and depress the brake pedal with a force of 147 N {15.0 kgf, 33.0 lbf}

2. Verify that the distance from the floor covering to the pedal pad center is as specified when the pedal is depressed.

- If the distance is less than specified, check for air in brake system.

Brake pedal-to-floor clearance (Brake pedal when depressed at 147 N {15.0 kgf, 33.0 lbf})
- 95.4 mm {3.76 in}
