Parking Brake Adjustment
The parking brake needed to be adjusted as it no longer stopped the rear wheels from turning.
The first step is to unbolt the brake from the bracket which is attached to the body of the car. This provides access to the adjustment screw.
Adjusting the parking brake took a little bit of guess work. I would unlock the top bolt and then spin the adjustment bracket a few threads to tighten it. Then I would reattach everything, pull up on the parking brake and check the wheels. Clarks Garage states that pulling up on the brake 3 clicks should provide some resistance in the wheels so I kept adjusting until I hit that point.
