(1) Before removing the brake disk, make marks using a 

chalk to the stud bolt on the side with the greater runout 
and to both sides of the stud bolt.

(2) Check the wheel bearing axial looseness. (Refer to 

GROUP 26 

− On-vehicle Service, Wheel Bearing End 

Play Check 

P.26-7

 <Front> or GROUP 27 

− On-vehicle 

Service, Wheel Bearing End Play Check 

P.27-33

 

<Rear>.)

(3) When the looseness is within the limit value, install the 

brake disk after changing the phase between the hub and 
the brake disk, then check the runout of the brake disk 
again.

CAUTION

• After a new brake disk is installed, always grind the 

brake disk with on-the-car type brake lathe. If this step 
is not carried out, the brake disk run-out exceeds the 
specified value, resulting in judder.

M12 Flat washer

M12 Flat washer

When the on-the-car type lathe is used, first install M12 
flat washer on the stud bolt in the brake disk side 
according to the figure, and then install the adapter. If 
the adapter is installed with M12 flat washer not seated, 
the brake disk rotor may be deformed, resulting in inac-
curate grinding.

• Grind the brake disk with all wheel nuts diagonally and 

equally tightened to the specified torque 100 N

⋅ m (74 

ft-lb). When all numbers of wheel nuts are not used, or 
the tightening torque is excessive or not equal, the 
brake disk rotor or drum may be deformed, resulting in 
judder.

5. If the run-out cannot be corrected by changing the phase of 

the brake disk, replace the brake disk or grind it with the 
on-the-car type brake lathe ("MAD, DL-8700PF" or 
equivalent).

BRAKE DRAG FORCE CHECK

1. Remove the brake pad, shim, and clip. (Refer to 

P.35A-18

.)

AC707502AB

Front of vehicle

2. Using a spring scale, and with the brake pad, shim, and clip 

removed, measure the hub sliding torque in the forward 
direction.

3. Install the brake pad, shim, and clip. (Refer to 

P.35A-18

.)

4. Start the engine, and depress the brake pedal forcibly two or 

three times. Then, stop the engine.

5. Rotate the brake disk 10 times in the forward direction.
6. Using a spring scale, and with the brake pad, shim, and clip 

installed, measure the hub sliding torque in the forward 
direction.

7. Obtain the disk brake drag force (difference between 

measured values of Step 2 and Step 6).

Standard value: 

68 N (15.3 pounds) or less <Front>
68 N (15.3 pounds) or less <Rear>

8. If the brake drag force exceeds the standard value, 

disassemble the brake caliper assembly, and check the 
fouling/rust on the piston sliding section, piston seal 
deterioration, and the sliding status of guide pin and lock pin. 
(Refer to 

P.35A-35

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.

Continuity

1. Connect a circuit tester (

Ωrange) to the stoplight switch 

connector.

2. When no continuity is detected with the plunger pressed 

from the edge of the outer case by the dimension shown in 
the figure and when continuity is detected with the plunger 
released, the stoplight switch is in good condition.

1. Place the brake pedal assembly on a level surface as shown 

in the figure, and set the distance from the center of the pin 
assembly mounting hole to the level surface to 97 mm (3.82 
inch). Make sure that the dimension A in the figure (distance 
from the pedal pad center part to the level surface) is within 
the standard value.

Standard value (A):

− 246 mm (9.4 − 9.7) <M/T>

242 

− 248 mm (9.5 − 9.8) <TC-SST>
