BRAKE SYSTEM (OTHER): BRAKE PEDAL: ADJUSTMENT

1. INSPECT AND ADJUST BRAKE PEDAL HEIGHT

(a) Check the brake pedal height.

(1) Turn back the carpet.

(2) Turn back the dash panel insulator assembly from the slit provided on the dash panel insulator assembly.

(3) Measure the shortest distance between the brake pedal pad surface and floor panel.

Pedal height from floor panel:

138.5 to 148.5 mm (5.46 to 5.84 in.)

If pedal height is incorrect, inspect and adjust the push rod length according to the procedure below.

(b) Adjust the push rod length.

(1) Remove the stop light switch assembly Removal.

(2) Remove the brake booster assembly Removal.

(3) Loosen the lock nut and adjust the push rod length shown in the illustration by turning the brake master cylinder push rod clevis to achieve the correct length.

(4) Tighten the lock nut.

Torque : 26 Nm (265 kgf-cm, 19 ft-lbf)

(5) Install the brake booster assembly Installation.

* If the pedal height is incorrect even when the push rod length is adjusted, check the brake pedal support assembly and floor panel.

* If necessary, replace the brake pedal support assembly.

(6) Install the stop light switch assembly Installation.

(c) After adjusting the pedal height, check the brake pedal free play.

2. INSPECT BRAKE PEDAL FREE PLAY

(a) Stop the engine and firmly depress the brake pedal several times until no vacuum is left in the booster.

(b) Depress the pedal until a slight resistance is felt. Measure the distance as shown in the illustration.

Pedal free play:

1.0 to 6.0 mm (0.0394 to 0.236 in.)

If the pedal free play is not as specified, check the stop light switch clearance Installation. If the pedal free play is as specified, proceed to the Inspect Brake Pedal Reserve Distance procedure.

3. INSPECT BRAKE PEDAL RESERVE DISTANCE

HINT
Measure the distance at the same point used for the brake pedal height inspection.

(a) Release the parking brake.

(b) With the engine running, depress the brake pedal and measure the pedal reserve distance.

Pedal reserve distance from the floor panel at 500 N (51 kgf, 112 lbf):

More than 96.0 mm (3.78 in.)

If the distance is not as specified, troubleshoot the brake system Testing and Inspection.
