Brake Pedal Assy: Testing and Inspection
BRAKE PEDAL HEIGHT1. Turn up the carpet etc. under the brake pedal.
2. Measure the brake pedal height as illustrated. If it is not within the standard value, adjust as follows.
Standard value: 176 - 181 mm (6.9 - 7.1 inches) From the surface of melting sheet (floorboard) to the face of pedal pads
1. Disconnect the stoplight switch connector, loosen the jam nut and move the stoplight switch to a position where it does not contact the brake pedal arm.
2. Adjust the brake pedal height by fuming the operating rod with pliers (with the operating rod jam nut loosened).
3. Screw in the stoplight switch until it contacts the brake pedal stopper Just before brake pedal begins to move). Return the stoplight switch had to one turn and secure with the jam nut.
4. Connect the connector of the stoplight switch.
5. Check to be sure that the stoplight is not illuminated the brake pedal released.
3. Turn back the carpet etc. to original position.
BRAKE PEDAL FREE PLAY
1. Turn the ignition switch to the "LOCK" (OFF) position, depress the brake pedal two or three times. After eliminating the vacuum in the brake booster, press the pedal down by hand, and confirm that the amount of movement before resistance is met (free play) is within the standard value range.
Standard value: 3 - 8 mm (0.1 - 0.3 inch)
2. If the free play exceeds the standard value, it is probably due to excessive play between the clevis pin and brake pedal arm.
3. Check for excessive clearance and replace faulty parts as required.
CLEARANCE BETWEEN BRAKE PEDAL AND FLOORBOARD
1. Turn up the carpet etc. under the brake pedal.
2. Start the engine, depress the brake pedal with approximately 490 N (110 pound) of force, and measure the clearance between the brake pedal and the floorboard.
Standard value: 95 mm (3.7 inches) or more (From the surface of melting sheet (floorboard) to the face of pedal pads
3. If the clearance is outside the standard value, check for air trapped in the brake line, clearance between the lining, and the drum and dragging in the parking brake. Adjust and replace defective parts as required.
4. Return the carpet etc. to its original position.
