Road Test

NOTE: Do not alter the vehicle prior to the Road Test. Any change may affect the intensity of the driver concerns and prevent an accurate diagnosis.

NOTE: The test driver should have a thorough knowledge of brake system operation and accepted general performance guidelines in order to make valid comparisons and detect performance problems.

Perform a Road Test to compare the vehicle braking performance with the driver concerns.

The Road Test should be performed on a smooth and level road. For optimum traction and control during the road test, avoid gravel, crowned or uneven road surfaces.

Begin the Road Test with a general brake performance check.
This includes:

• Test the brakes at different speeds using light, moderate, and heavy pedal pressure.
• Be alert to noises, vibrations, and pulling or drifting conditions.
• Avoid locking the brakes and skidding the tires. Locked brakes do not indicate braking efficiency.
