Either the front or rear brakes will not be fully operable.

None of the brakes will work at all.

Either the front or rear brakes will not be fully operable.

Some older vehicles have front brake limiting valves with "normal" and "slippery" settings. Setting a brake limiting valve to "slippery" reduces the vehicle's stopping power, so a driver should make sure the valve is in its "normal" position.

Set the control to the off position.
