A rotating component in brake systems that converts kinetic energy into thermal energy through friction to decelerate or stop vehicles.
The brake drum or rotor is a critical rotating component in automotive and industrial braking systems. In drum brake configurations, it's a cylindrical component where brake shoes press outward against its inner surface. In disc brake systems, the rotor is a flat, circular metal disc that rotates with the wheel, with brake pads clamping on both sides. Both designs function by converting kinetic energy into thermal energy through friction, enabling controlled deceleration and stopping of vehicles or machinery.

Brake drums are cylindrical components used in drum brake systems where brake shoes press outward. Rotors are flat discs used in disc brake systems where pads clamp on both sides. Disc brakes generally offer better heat dissipation and performance.
Typically every 50,000-70,000 miles, but depends on driving conditions, vehicle weight, and braking habits. Replace when thickness falls below minimum specifications or when scoring/cracking occurs.
Uneven heat distribution during braking, improper torque during installation, or rapid cooling (like driving through water when hot) can cause thermal stress leading to warping.
