Pictures of Parking Brake Adjustment
I am posting some pictures of this job:
Picture 1) Shows the rubber plug that covers the hole. This must be removed to rotate the adjuster star wheel that tightens the parking brake. The rubber plug should be replaced when done to keep water and road grit out.
Picture 2) Shows the star wheel through the hole.
Picture 3) Shows a tool that is designed to adjust the parking brake, but a screw driver will do. The brake can be adjusted while the tires are on the ground.
If you could reach your thumb through the hole, you can't, you would rotate the side of the star wheel you can see in picture 2 down toward the ground to tighten the brake.
