The basis of a drum brake system. It is a circular metal component which rotates with the road wheel. A set of brake shoes which are fixed in position and act on the drum by expanding.

A metal housing, shaped like an oversized jar lid and bolted to an axle and a vehicle wheel. Brake shoes covered with a friction material are forced against the circular inner surface of the drum to stop the rotating wheel.  Figure 2. Brake Drum

The shallow cylindrical rotating member of a drum brake. The friction material on the brake shoes (see) is pressed against its inside surface during braking.

One of a set of four cylindrical cast iron or pressed steel drums housing friction-lined shoes to slow down the rotation of the wheels.

A drum-shaped iron, steel, or aluminum housing rotating inboard with the wheel that the brake shoes press against.

a hollow cast-iron cylinder attached to the wheel that forms part of the brakes

a flat-topped and heavy cylinder, that you normally find somewhere between the wheel rim and the drive wheel

Rotating part of the drum brake system connected to the wheels; brake shoes press against the drum causing friction which stops the wheel.

A round cast iron or aluminum housing that rotates around fixed brake shoes and is slowed or stopped when the shoes are expanded. Flushing - A method of cleaning a hydraulic system by bleeding brake fluid through the system.

the part of a drum brake system that rotates with the wheel.

Metal housing bolted to an axle and vehicle wheel that looks like a large jar lid. Brake shoes are forced against the drum to stop rotating wheels.

It is the large circular surface that is pressed against by the brake shoe to stop the vehicle.
