Drum reconditioning is the process of restoring used brake drums to a safe and functional condition. This involves cleaning, inspecting, and machining the drum's surface to remove any wear or damage. The goal is to ensure that the drum can effectively work with the brake shoes to provide reliable stopping power. During reconditioning, technicians check for cracks, warping, or excessive wear. If the drum meets safety standards, it can be resurfaced to improve its performance. This process is often more cost-effective than purchasing new drums, making it a popular choice for vehicle maintenance and repair.
