Operation CHARM: Car repair manuals for everyone.

Brake System Testing

Test the brakes on a roadway that meets all of the following conditions:
^ Dry
^ Clean
^ Reasonably smooth
^ Level

Test the brakes at different vehicle speeds with both light and heavy brake pedal force.

Do not test the brakes on a roadway with the following conditions because the tires will not grip the road equally:
^ Wet
^ Greasy
^ Covered with loose dirt

Do not test the brakes on a crowned roadway because the weight of the vehicle will be thrown toward the wheels on one side.

Do not test the brakes on a rough roadway because the wheels will tend to bounce.
