Road Test Description

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.
- 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.
