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.
