Drum Brake System: Description and Operation

The rear drum brakes consist of:
- non-servo,leading-trailing shoe design
- Sedan models use a 225 mm (8.85 inch) diameter brake drum.
- Automatic adjustment of the drum brake assemblies with an incremental adjuster that adjusts during braking whenever a wear gap is sufficient to actuate the adjuster wheel.
- Brake adjustment occurs in forward braking.
- rear brake backing plate mounted to the rear wheel spindle

The hydraulic rear drum brakes are:
- self-adjusting and require a manual adjustment only after the rear brake shoes and linings have been replaced or when the length of the brake adjuster screw has been changed while performing some other service operation.
- The manual adjustment is performed with the brake drum removed.
