Jor Did you check your Emergency Break Cable.
With the Rear Wheels jacked up you should be able to turn them freely.
Lift the Emergency Break 3 Clicks and the wheel should stop turning.
Don't know where the adjustment is for Foci, my blazer had a cable running under the chassis, which I adjusted with a deep socket.
