PARKING BRAKE DIAGNOSIS

INTRODUCTION

M1361003700282

If the parking brake is faulty, parking brake effort will 
become insufficient. The cause may be a malfunc-
tion of parking brake parts or the parking brake pedal 
being out of adjustment.

TROUBLESHOOTING STRATEGY

M1361003800290

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 PROCEDURES

INSPECTION PROCEDURE 1: Insufficient Parking Brake Function

DIAGNOSIS

STEP 1. Check the excessive parking brake lever 
stroke.
 Refer to 

P.36-3

.

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.
 Refer to 

P.36-11

.

Q: Is the brake lining thickness or brake drum inside 

diameter outside of specification?
YES : 

Replace the rear brake shoe assembly or 
rear brake disc (Refer to 

P.36-8

). Then go to 

Step 5. 

NO : 

Go to Step 4.

STEP 4. Check for oil, water, etc., on the lining 
contact surfaces.

Q: Is oil, water, etc., on the lining contact surface?

YES : 

Replace the part and determine and repair 
source/cause of foreign material. Then go to 
Step 5.

NO : 

Carry out the parking brake lining seating 
(Refer to 

P.36-5

) 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.

PARKING BRAKE LEVER STROKE CHECK AND 
ADJUSTMENT

M1361000900362

1. Pull the parking brake lever with a force of approximately 

200 N (45 pounds) and count the number of notches.

Standard value: 5 

− 7 notches

2. If the parking brake lever stroke is not within the standard 

value, adjust as described below. 

(1) Release the parking brake.

(2) Remove the console inner box tray and plate (Refer to 

GROUP 52A, Floor Console Assembly 

P.52A-9

), and 

then loosen the adjusting nut to move it to the cable rod 
end so that the cable will be free.

(3) Remove the rear wheels, and then remove the 

adjustment hole plug on the brake disc.

(4) Use a flat-tip screwdriver to turn the adjuster in the 

direction of the arrow (the direction which expands the 
shoe) so that the disc will not rotate by hand. Return the 
adjuster five notches in the direction opposite to the 
direction of the arrow.

(5) Install the rear wheels, and then tighten the wheel nuts to 

98 

± 10 Nm (73 ± 7 ft-lb).

CAUTION

Be careful that the parking brake lever stroke should be 
within the standard value. If the stroke is too short, brake 
dragging can be caused.

(6) Turn the adjusting nut to adjust the parking brake lever 

stroke to the standard value. After adjustment, check that 
the adjust nut and the cable rod is not loose.

(7) Release the parking brake and turn the rear wheels to 

check that the rear brakes are not dragging.

3. If either of the parking brake cables is replaced, adjust the 

parking brake lever stroke as described previously, pull the 
parking brake lever 10 times with approximately 200 N (45 
pounds) to eliminate the initial slack of the cable. Then 
adjust the parking brake lever stroke as described 
previously again.

CAUTION

Perform lining seating in a place with good visibility, and 
pay careful attention to safety.
Perform lining seating by the following procedure when replac-
ing the parking brake shoe assemblies or the rear brake discs, 
or when brake performance is insufficient.

(Refer to 

P.36-3

).

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).
