brake drums

Friction housing components

Brake drums are cylindrical components in drum brake systems, rotating with the wheel while brake shoes press outward against their inner surface to create friction and slow the vehicle.

Once standard on all four wheels, drum brakes now typically appear only on rear wheels, with disc brakes preferred for front wheels: The mechanic said the brake drums were worn and needed replacing.
