GENERAL DESCRIPTIONM1361000100344
The parking brakes are a mechanical rear wheel
brake design and controlled by a lever.

PARKING BRAKE DIAGNOSIS
INTRODUCTIONM1361003700282
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 STRATEGYM1361003800290
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
St e p 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.
ON-VEHICLE SERVICE
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.

ON-VEHICLE SERVICE
PARKING BRAKES36-4
(2) Remove the console inner box tray and plate (Refer to
GROUP 52A, Floor Console Assembly P.52A-10), 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).
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.

PARKING BRAKE SWITCH CHECKM1361003300411
1. Remove the floor console. (Refer to GROUP 52A, Floor
Console P.52A-10.)
2. Check for continuity between the parking brake switch
terminal and the switch mounting bolt.
PARKING BRAKE LINING SEATING PROCEDUREM1361001100262
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.
1. Adjust the parking brake lever stroke to the standard value
(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).
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.When parking brake pedal is pulled 2 ohms or less
