Honda drum brakes use a design "master-slave", which uses two curved brake pads held by an anchor shield and a wheel cylinder. When the brake pedal is depressed and hydraulic pressure is applied to the wheel cylinder, the wheel cylinder pistons press the shoes against the drum.
The friction between the brake pads and the drum causes the car to slow down and stop. When the brake pedal is released, the brake shoe return springs move it away from the drum. If the brake lining gets dirty or scratched, the brakes will interact very violently with the drum, causing the brakes to stick and/or squeal.
If the brake pads on one wheel make contact with the drum before the other wheels, braking will occur on one side. In poorly adjusted brakes, the distance between the shoe and the drum is too large; this renders the parking brake ineffective and also requires more brake response time to the pedal stroke.
