Turn OFF the ignition.
Remove the front floor console. Refer to Front Floor Console Replacement.
With the park brake lever in the released position, loosen the adjusting nut (1)
enough to completely relieve tension on the front cable.
Raise and support the vehicle. Raise the vehicle just enough to allow the rear

drag exists, verify the park brake apply levers are fully against the stops on the
rear brake calipers.

If the tire and wheel assemblies do not rotate freely, repeat the park brake
cable adjustment procedure.
