Rear drum brakes (Honda Accord 3)

Honda drum brakes use a master-slave design, which uses two curved brake shoes held in place by a backplate and wheel cylinder. When the brake pedal is depressed and hydraulic pressure is applied to the wheel cylinder, the wheel cylinder pistons force the shoes against the drum.

Friction between the brake shoes and the drum causes the vehicle to slow and stop. When the brake pedal is released, the brake shoe return springs pull it away from the drum. If the brake lining becomes dirty or scratched, the brakes will interact very harshly with the drum, causing the brakes to stick and/or squeal.

If the brake shoes 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 makes the parking brake ineffective and also requires a longer brake response time to pedal pressure.
