Road Test

NOTE: Do not alter the vehicle prior to the road test. Any change may affect the intensity of the driver's concerns and prevent an accurate diagnosis.

- Perform a road test to compare the vehicle's braking performance with the customers concerns. 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.
- The road test should be performed on a smooth and level road.
- Begin the road test by applying the brakes at different speeds using light, moderate and heavy pedal pressure. During the road test, be alert to noises, vibrations and pulling or drifting conditions.
- Avoid locking the brakes and skidding the tires. Locked brakes are not an indicator of braking efficiency.
- If a problem exists, refer to Diagnosis by Symptom. Symptom Related Diagnostic Procedures
