Brake Pedal Assy: Adjustments

SERVICE ADJUSTMENT

PROCEDURES

PEDAL HEIGHT
1. Measure the brake pedal height. If the brake pedal height is not within the standard value, adjust as follows.

Standard value : 189 mm (7.24 in.)





2. Disconnect the stop lamp switch connector, loosen the lock nut(A), and move the stop lamp switch to a position where it does not contact the brake pedal arm.
3. Adjust the brake pedal height by turning the operating rod with pliers (with the operating rod lock nut loosened), until the correct brake pedal height is obtained.




4. After turning the stop lamp switch(A) until it contacts the brake pedal stopper(B) (just before the brake pedal is caused to move), return the stop lamp switch 1/2 to 1 turn and secure by tightening the lock nut.




5. Connect the connector of the stop lamp switch.
6. Check that the stop lamp is not illuminated with the brake pedal unpressed.

PEDAL FREE PLAY
1. With the engine stopped, depress the brake pedal two or three times. After eliminating the vacuum in the power brake booster, press the pedal down by hand, and confirm that the amount of movement before resistance is met (the free play) is within the standard value.

Standard value : 3 - 8 mm (0.117 - 0.312 in.)





2. If free play does not reach the standard value, check that clearance between the outer case of stop light switch and brake pedal is within the standard value.
If free play exceeds the standard value, it is probably due to excessive clearance between the clevis pin and brake pedal arm.
Check for excessive clearance and replace faulty parts as required.
3. Start the engine, depress the brake pedal with approximately 120kg(1176.8N, 264.5 lb) of force, and check for oil leakage in the master cylinder, brake line and each connecting part.
Repair the faulty parts as required.
