Brake Pedal Assy: Testing and Inspection

BRAKE PEDAL INSPECTION

Pedal Height Inspection

1. Measure the distance from the steering shaft cover to the center of the upper surface of the pedal pad and verify that it is as specified.






- If not within the specification, replace the pedal component.

Pedal height (reference value)
- 192 mm {7.56 in}

Pedal play inspection

1. Pump the pedal several times to release the vacuum in the power brake unit.

2. Gently depress the pedal by hand and measure the pedal play.

- If not within the specification, inspect the wear of the clevis pin. Replace it if there is any malfunction.

Standard pedal play
- 2.6-4.7 mm {0.11-0.18 in}

NOTE:
- If there is no malfunction in the clevis pin, there is a possibility that the power brake unit has some malfunction. Verify that there are no malfunctions and perform part replacement if necessary.

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. Measure the distance between the floor panel and the pedal pad center and verify that the dimensions are as shown in the figure.






- If the pedal-to-floor clearance is less than the specification, inspect for air in the brake system.

Standard pedal-to-floor clearance
- 70.8 mm {2.79 in} or more
