Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Brake Test
- Keep the front or rear wheels on the ground during measurement.
- When the brake dragging force is large, inspect whether there is dragging in the brake 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, check if braking force measurement in this condition conforms to standard grand total.
