April 5, 2026: LEMON Manuals is launched! Read the announcement.

Brake Test

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 stabilize 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.

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 viscous coupling, jack up either of the front or rear two wheels to check the each wheel rotation condition with the viscous coupling affection removed.

Full-time AWD AT model

Keep the front or rear wheels on the ground during measurement.

When the brake dragging force is large.

Check the dragging of brake pad or brake shoe.

Specifications:

	Braking force
Rear wheel total	10% or more of load on front or rear wheels
Difference between right and left wheels	8% or less of load on front or rear wheels
Grand total	50% or more of vehicle weight at the time of test

When measurement is difficult to carry out because both of front wheels are locked, break force measurement in this condition conforms to standard grand total.
