Ensure the following conditions are present when testing
the brakes:
• | Test the brakes on a dry roadway. |
• | Test the brakes on a clean roadway. |
• | Test the brakes on a reasonably smooth roadway. |
• | Test the brakes on a reasonably level roadway. |
• | Test the brakes in an area that is free of vehicular and pedestrian
traffic. |
The following conditions prevent a true test of brake performance:
• | A wet roadway prevents the tires from equally gripping the roadway. |
• | Road oil prevents the tires from equally gripping the roadway. |
• | A roadway covered with loose dirt prevents the tires from equally
gripping the roadway. |
• | A crowned roadway throws the weight of the vehicle toward the
wheels on one side. |
• | A rough roadway bounces the wheels. |
Test the brakes at different vehicle speeds with both light and heavy
brake pedal pressure.
