ADJUSTMENT

PROCEDURE

1. INSPECT AND ADJUST BRAKE PEDAL HEIGHT

(a) Check the brake pedal height.

(1) Turn back the carpet.

(2) Measure the brake pedal height from the dash panel to the bottom edge of the brake pedal pad. Text in Illustration *1 Lock Nut *2 Stop Light Switch Assembly *3 Dash Panel *4 Brake Pedal Height Standard pedal height: 135 to 145 mm (5.31 to 5.71 in.) If pedal height is incorrect, adjust the push rod length according to procedure below.

(b) Adjust the push rod length.

(1) Remove the stop light switch assembly (See page ).

(2) Remove the brake booster assembly (See page ).

(3) Loosen the lock nut and adjust the push rod length*1 shown in the illustration by turning the brake master cylinder push rod clevis to achieve the length*1. Text in Illustration *1 Push Rod Length *2 Lock Nut *3 Brake Master Cylinder Push Rod Clevis Length*1: 155.1 to 156.1 mm (6.11 to 6.15 in.)

(4) Tighten the lock nut.

Torque:

26 N·m {265 kgf·cm, 19 ft·lbf}

(5) Install the brake booster assembly (See page ).

If the pedal height is incorrect even if the push rod length is adjusted, check that there is no damage to the brake pedal support assembly and dash panel.

(6) Install the stop light switch assembly (See page ).

(7) Check that the stop lights do not come on when the brake pedal is released.

(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) Measure the free play of the brake pedal. Text in Illustration *1 Brake Pedal Free Play Standard pedal free play: 1.0 to 3.0 mm (0.0394 to 0.118 in.) If the pedal free play is not as specified, check the stop light switch clearance (See page ). 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) Start the engine.

(b) Depress the brake pedal and check the pedal reserve distance.

(1) Depress the brake pedal with a force of 500 N (51 kgf, 112.4 lbf).

(2) Measure the distance between the brake pedal and dash panel.

Standard pedal reserve distance:

28 mm (1.10 in.)

If the distance is not as specified, troubleshoot the brake system (See page ).
