Rolling Road Testing

Rolling Road Testing

General

IMPORTANT: Use a four wheel rolling road for brake testing if possible.

Four Wheel Rolling Road
Provided that front and rear rollers are rotating at identical speeds and that normal workshop safety standards are applied, there is no speed restriction during testing except any that may apply to the tires.

CAUTION: Ensure that gearbox selector lever is at 'N', hill descent control is not selected and handbrake is released.

When checking brakes, run engine at idle speed to maintain servo vacuum.

Two Wheel Rolling Road
If brake testing on a two wheel rolling road, then the following precautions must be taken:
^ Disconnect propeller shaft from the transfer box shaft driving the axle whose wheels are NOT on the rolling road.
^ Neutral selected in gearbox.
