Mitsubishi Outlander: On-vehicle Service

BRAKE PEDAL INSPECTION

CAUTION Do not apply grease or lubricant to the switch and the switch installation section to avoid malfunction of the switch. In addition, do not use gloves which have grease on them.

BRAKE PEDAL HEIGHT CHECK

1. Turn up the floor carpet under the brake pedal.

2. Remove the stoplight switch.

3. Use a needle or similar tool to measure the dimension A in the figure (distance from the dash panel pad surface to the dash panel).

4. Measure the dimension B in the figure (distance from the pedal pad surface to the dash panel pad surface).

5. Make sure that the total of the dimensions A and B measured in Steps 2 and 3 (brake pedal height) is within the standard value.

Standard value (A+B): 221.8 − 227.8 mm (8.7 − 9.0 inch)

6. When the brake pedal height is not within the standard value, inspect the brake pedal in the following procedure.

  1. Remove the brake pedal assembly.
  2. Check the removed brake pedal assembly for distortion, and replace it when deformed.
  3. Install the brake pedal assembly.

NOTE: When installing, compress the dash panel pad.

  1. Measure the brake pedal height again, and make sure that it is within the standard value (A+B).

    When the measured value is not within the standard value, measure the dimension C in the figure (distance from the stud bolt end to the clevis hole center), and make sure it is within the standard value (C).

    Standard value (C): 75.8 − 80.2 mm (2.98 − 3.16 inch)

  2. When the measured value is not within the standard value (C), replace the brake booster.

7. After checking the brake pedal height, install the stoplight switch in the following procedure:

  1. Screw in the stoplight switch until its thread contacts the pedal stopper, then turn the switch approximately one eighth of a clockwise turn to fix it. While doing this, pull and hold the brake pedal by hand.
  2. Check that the clearance between the stoplight switch and the pedal stopper is as shown in the figure.

CAUTION Make sure that the stoplight is not illuminated when the brake pedal is not depressed.

  1. Connect the stoplight switch connector.

8. Check the key interlock mechanism and the shift lock mechanism.

9. Recover the floor carpet under the brake pedal.

BRAKE PEDAL PLAY CHECK AND ADJUSTMENT

1. With the engine stopped, depress the brake pedal 2 or 3 times to relieve the vacuum in the brake booster. Then, press the brake pedal with your finger and check if the pedal stroke until the pedal becomes heavy (play) is within the standard value.

Standard value (B): 3 − 8 mm (0.12 − 0.31 inch)

2. When the brake pedal play is not within the standard value, check the brake pedal-to-clevis pin looseness, clevis pin-to-booster operating rod looseness, brake pedal height, and stoplight switch position, and adjust or replace as necessary.

BRAKE PEDAL-TO-FLOOR PANEL CLEARANCE CHECK AND ADJUSTMENT

1. Turn up the floor carpet under the brake pedal.

2. Start the engine and depress the brake pedal with approximately 500 N (112 pounds), and measure clearance between the brake pedal and the floor panel.

Standard value (C): 80 mm (3.15 inch) or more

3. When the clearance is not within the standard value, check for the air in the brake line and thickness of the disc brake pad, and correct or replace as necessary.

4. Recover the floor carpet under the brake pedal.

BRAKE BOOSTER OPERATION CHECK

INSPECTION WITHOUT USING TESTER

1. Carry out the simplified brake booster operation check in the following procedure:

  1. Run the engine for 1 to 2 minutes, and then stop.

    Depress the brake pedal with normal depression force.

    The result is judged as "Good" when the pedal stroke is great at the first depression, and becomes smaller as you repeat depressing the pedal. If the pedal stroke does not change, the result is judged as "No Good".

Mitsubishi Outlander. Basic Brake

  1. With the engine stopped, depress the brake pedal several times. Keep the brake pedal depressed and start the engine. At this time, when the pedal moves down slightly, the result is judged as "Good". The result is judged as "No Good" if the pedal does not moves down.

Mitsubishi Outlander. Basic Brake

  1. With the engine running, depress the brake pedal. Stop the engine in this condition. The result is judged as "Good" when the pedal height does not change for approximately 30 seconds. The result is judged as "No Good" if the pedal moves up.

2. The brake booster is judged as normal when the results of all the above checks are "Good". When one or more of the above check results are "No Good", then the check valve, vacuum hose, or brake booster is suspected faulty.

Mitsubishi Outlander. Basic Brake

INSPECTION USING SIMPLIFIED TESTER

1. Before starting this inspection, remove the brake booster check valve from the vehicle and check its operation.

2. After checking, install the check valve to the vacuum hose and connect it to the vacuum gauge. Install the booster test adapter (Special tool: MB992146) to the brake booster and connect it to the vacuum gauge. Connect the pressure gauge and pedal depression gauge as shown in the figure.

Bleed the pressure gauge and then perform the following tests:

  1. Airtightness test with no load
    Start the engine, and stop it when the vacuum gauge indicator has reached approximately −67 kPa (−9.7 psi).

    The result is judged as "Good" when the drop of the vacuum approximately 15 seconds after the engine was stopped is within −3.3 kPa (−0.5 psi).

  2. Airtightness test with load
    Start the engine and depress the brake pedal with 200 N.

    Stop the engine when the vacuum gauge indicator reached approximately −67 kPa (−9.7 psi). The result is judged as "Good" when the drop of the vacuum approximately 15 seconds after the engine was stopped is within −3.3 kPa (−0.5 psi).

    When one or more of the above check results are judged as "No Good", the vacuum hose or brake booster is suspected faulty.

Mitsubishi Outlander. Basic Brake

  1. Brake booster characteristics test
    Perform this test after the above (1) and (2) were performed.
    1. Non-servo effecnt test
      With the engine stopped, make sure that the vacuum gauge reading is 0 kPa (0 psi). Depress the brake pedal with 100 N and 300 N, and measure the fluid pressure generated.

Standard value:

 How To Diagnose (Electrical)

HOW TO DIAGNOSE The most important point in troubleshooting is to determine "Probable Cause". Once the probable causes are determined, parts to be checked can be limited to those associated with such probable causes. The determination of the probable causes must be based on a theory and be supported
