Which way do you turn a brake adjuster?

You only want the shoes to engage when the parking brake lever is engaged.
How do drum brake adjusters work?
Each time the car stops while in reverse, the shoe is pulled tight against the drum. When the gap gets big enough, the adjusting lever rocks enough to advance the adjuster gear by one tooth. The adjuster has threads on it, like a bolt, so that it unscrews a little bit when it turns, lengthening to fill in the gap.
What holds brake shoes to the backing plate?
Springs hold the brake shoes in place so they don’t contact the drum when the brakes aren’t active. When the driver pushes down on the brake pedal, this places pressure on the hydraulic fluid in the brake lines. At the top of the backing plate is a wheel cylinder containing two pistons, one at either end.
What tools are needed to change drum brakes?
You’ll need a drum brake retainer spring tool and a pair of drum brake spring pliers. These can often be purchased as a set. You’ll also need simple tools like a hammer, pliers, and other assorted hand tools to get everything apart.
