>A< Adjuster Installation.
Install the adjuster so that the shoe adjusting bolt of left hand wheel is attached towards the front of the vehicle, and the shoe adjusting bolt of right hand wheel is towards the rear of the vehicle.
>B< Shoe-To-Anchor Spring Installation.
The load on the respective shoe-to-anchor springs is different, so the spring in the figure has been painted.
