Parking Brake Diagnosis

INTRODUCTION

If the parking brake is faulty, parking brake effort will become insufficient. The cause may be a malfunction of parking brake parts or the parking brake lever being out of adjustment.

TROUBLESHOOTING STRATEGY

Use these steps to plan your diagnostic strategy. If you follow them carefully, you will be sure that you have exhausted most of the possible ways to find a parking brakes fault.

1. Gather Information from the customer.

2. Verify that the condition described by the customer exists.

3. Find the malfunction by following the Symptom Chart.

4. Verify malfunction is eliminated.

SYMPTOM CHART

SYMPTOM PROCEDURES

INSPECTION PROCEDURE 1: Insufficient Parking Brake Function

DIAGNOSIS

STEP 1. Check the excessive parking brake lever stroke.

Q: Is the parking brake lever stroke adjusted properly?

YES : Go to Step 2.

NO : Adjust the parking brake lever stroke or check the parking brake cable routing. Then go to Step 5.

STEP 2. Check the parking brake cable for sticking.

Q: Is the parking brake cable stuck?

YES : Replace the cable. Then go to Step 5.

NO : Go to Step 3.

STEP 3. Check the brake lining and brake drum for wear.

Q: Is the brake lining thickness or brake drum inside diameter outside of specification?

NO : Carry out the parking brake lining seating procedure and then go to Step 5.

STEP 5. Retest the system.

Q: Is the malfunction eliminated?

YES : The procedure is complete.

NO : Recheck from Step 1.

INSPECTION PROCEDURE 2: When the Parking Brake Lever is Pulled, the Brake Warning Light does not Illuminate.

TECHNICAL DESCRIPTION (COMMENT)

The parking brake switch turns on and off by operating the parking brake lever, and the brake warning light illuminates and goes out, indicating the operating status of parking brake to a driver.

TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THIS CASE:)

• Damaged wiring harness or connector
• Parking brake switch defective
• Combination meter defective

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
  • MB991824: Vehicle Communication Interface (V.C.I.)
  • MB991827: M.U.T.-III USB Cable
  • MB991910: M.U.T.-III Main Harness A

STEP 1. Using scan tool MB991958, check combination meter actuator test.

CAUTION To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958.

1. Connect scan tool MB991958 to the data link connector.
2. Turn the ignition switch to the "ON" position.
3. Turn the parking brake switch and brake fluid level switch to "OFF" position.
4. Set scan tool MB991958 to the actuator test mode.
   • Item 13: Indicator4: ON
     • The brake warning light illuminates.
   • Item 13: Indicator4: OFF
     • The brake warning light goes out.
5. Turn the ignition switch to the "LOCK" (OFF) position.

Q: Is the check result normal?

YES : Go to Step 2.

NO : Replace the combination meter (Refer to GROUP 54A, Combination meter assembly).

STEP 2. Check the parking brake switch.

Q: Is the parking brake switch normal?

YES : Go to Step 3.

NO : Replace the parking brake switch.

Then go to Step 6.

STEP 3. Connector check: D-125 parking brake switch connector, C-22 intermediate connector and C-03 combination meter connector

Q: Is the check result normal?

YES : Go to Step 4.

NO : Repair or replace the faulty connector (Refer to GROUP 00E, Harness Connector Inspection). Then go to Step 6.

STEP 4. Check the wiring harness for an open circuit between D-125 parking brake switch connector terminal No.1 and C-03 combination meter connector terminal No.4.

1. Disconnect D-125 parking brake switch connector from C-03 combination meter connector, and measure at the wiring harness side connector.
2. Measure the resistance between D-125 parking brake switch connector terminal No.1 and C-03 combination meter connector terminal No.4.

   OK: Continuity exists (2 Ω or less)

Q: Is the check result normal?

YES : Go to Step 5.

NO : A open circuit may be present in the wiring harness between D-125 parking brake switch connector terminal No.1 and C-03 combination meter connector terminal No.4. Repair the wiring harness if necessary, and then go to Step 6.

STEP 5. Retest the system.

Q: Does the brake warning light illuminate when the parking brake lever is pull?

YES : It can be assumed that this malfunction is intermittent (Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points − How to Cope with Intermittent Malfunction).

NO : Replace the combination meter (Refer to GROUP 54A, Combination meter assembly).

STEP 6. Retest the system.

Q: Does the brake warning light illuminate when the parking brake lever is pulled?

YES : The procedure is complete.

NO : Return to Step 1.

PARKING BRAKE LEVER STROKE CHECK AND ADJUSTMENT

STROKE CHECK

Attach the spring scale to the center of the parking brake lever grip. Then, check that the stroke is within the standard value when the parking brake lever is pulled to the vertical direction of the lever with a force of approximately 200 N (45 pounds).

Standard value: 3 to 5 notches

STROKE ADJUSTMENT

If the parking brake lever stroke is out of the standard range, adjust as described below:

1. Remove the rear floor console assembly.

2. Loosen the adjusting nut to the end of the cable rod in order to allow slack in the cables.

3. Remove the rear brake disc adjusting hole plug. Then insert a flat-tipped screwdriver to turn the adjuster to the arrow direction (to expand the shoe) until the parking brake shoe makes contact and the disc can no longer be turned. Back off the adjuster to the opposite direction by five notches.

CAUTION Be careful that the parking brake lever notch number should be within the standard range. If the notch number is too low, rear brake dragging can be caused.

4. Adjust the parking brake lever stroke to the standard value by turning the adjusting nut. After adjustment, check that there is no free play between the adjusting nut and the parking brake lever.

5. After the parking brake lever stroke is adjusted, raise the rear of the vehicle. Release the parking brake, and turn the rear wheels to confirm that the rear brakes are not dragging.

PARKING BRAKE SWITCH CHECK

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.

1. Remove the rear floor console assembly.

2. Check for continuity between the parking brake switch terminal and the switch mounting bolt.

PARKING BRAKE LINING SEATING PROCEDURE

CAUTION Perform lining seating in a place with good visibility, and pay special attention to safety.

Perform lining seating by the following procedure when replacing the parking brake shoe assemblies or the rear brake discs, or when brake performance is insufficient.

1. Adjust the parking brake lever stroke to the standard value.

2. Hook a spring scale onto the center of the parking brake lever grip and pull it with a force of 98 − 147 N (22 − 33 pounds) in a direction perpendicular to the handle.

3. Drive the vehicle at a constant speed of 35 − 50 km/h (22 − 31 mph) for 100 meters (328 feet).

4. Release the parking brake and let the brakes cool for five to ten minutes.

5. Repeat the procedure in steps 2. to 4. four to five times.

Parking Brake Lever

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.
