For 1990-2009 cars only
| • | Test the brakes on a roadway that meets the following conditions: |
| • | Dry |
| • | Clean |
| • | Reasonably smooth |
| • | Level |
| • | Do not test the brakes on a roadway with the following conditions because the tires will not grip the road equally: |
| • | Wet |
| • | Greasy |
| • | Covered with loose dirt |
| • | Do not test the brakes on a crowned roadway because the weight of the vehicle will be thrown toward the wheels on one side. |
| • | Do not test the brakes on a rough roadway because the wheels will tend to bounce. |
| • | Test the brakes at different vehicle speeds, with both light and heavy brake pedal pressure. |
| • | If the vehicle is not equipped with an Antilock Brake System, avoid locking the brakes and sliding the tires. Locked brakes and sliding tires do not indicate brake efficiency, since heavily braked but turning wheels will stop a vehicle in less distance than locked wheels. |
| • | The brake system is balanced in order to avoid locking the wheels except at very high deceleration rates. Because of a high deceleration capability, a firmer brake pedal may be felt at higher deceleration levels. |
