14.BRAKE TEST
1) Full-time AWD MT model
(1) Perform this test after driving the vehicle 2 to
3 km (1.24 to 1.86 miles) on road in order to sta-
bilize the viscous torque of viscous coupling.
(2) Keep the front or rear wheels on the ground
for this test.
NOTE:
Effect of the viscous torque on braking force will be
added approx. 25 kg compared with FWD model.
(C)
(A) Brake tester
(B) Position for measuring front wheel
(C) Position for measuring rear wheel
(3) When the brake dragging force is large.
• Check the dragging of brake pad or brake shoe.
• Since it may be affected by the viscosity of vis-
cous couping, jack up either of the front or rear two
wheels to check the each wheel rotation condition
with the viscous coupling affection removed.
2) Full-time AWD AT model
(1) Keep the front or rear wheels on the ground
during measurement.
(C)
(A) Brake tester
(B) Position for measuring front wheel
(C) Position for measuring rear wheel

(2) When the brake dragging force is large.
• Check the dragging of brake pad or brake shoe.
Specifications:
Braking force
Rear wheel total More than 10% of load on front or rear
wheels
Difference between Less than 8% of load on front or rear
right and left wheels
wheels
Grand total More than 50% of vehicle weight at
the time of test
• When measurement is difficult to carry out be-
cause both of front wheels are locked, bake force
measurement in this condition conforms to stan-
dard grand total.
15.ON THE CAR WHEEL BALANCING
CAUTION:
• Carry out this procedures after measuring
the balance of each single tire.
• Set the vehicle so that the front and rear
wheels are the same height.
• Release the parking brake during measure-
ment.
• Rotate each wheel by hands, and make sure it
rotates without dragging.
• Do not operate the clutch quickly and do not
accelerate or decelerate suddenly during work.
• When an error is indicated during engine
drive, do not use the motor drive together.
1) Set the rigid rack to the specified locations of
side sill, jack up the front or rear two wheels of non-
measuring side and set the pickup stands to two
wheels of measuring side.
(B)
(A) Balancer body
(B) Pickup stand
2) For drive wheel, drive the tires with engine for
measurement.
3) For non-drive wheel, drive the tires from the on
the car wheel balancer for measurement.
