Understanding Brake Drum Turning Process

Brake drum turning is an essential process to ensure the smooth operation of your vehicle’s braking system. Over time, brake drums can become worn, warped, or corroded, which can negatively impact their performance. Turning the brake drums is a cost-effective way to restore their functionality without the need for a complete replacement. In this article, we will provide an overview of the brake drum turning process, the tools and equipment needed, and a step-by-step guide.

Overview Of Brake Drum Turning

Brake drum turning involves machining the surface of the drum to restore its smoothness and remove any imperfections. This process is performed on a lathe machine, which rotates the brake drum while a cutting tool shaves off a thin layer of the drum’s surface. By doing so, any irregularities in the drum’s surface are eliminated, ensuring proper contact between the brake shoes and the drum. This improves braking performance, reduces noise, and prevents brake pedal pulsation.

Tools And Equipment Needed

To turn brake drums, you will need the following tools and equipment:

• Lathe machine: This is the primary tool used to perform the drum turning process. Make sure the lathe machine is in good working condition and properly calibrated.
• Brake drum adapter set: These adapters are necessary to securely mount the drum on the lathe machine. Different adapters are available to fit various drum sizes.
• Cutting tool: This is the part of the lathe machine that removes the thin layer from the drum’s surface. Ensure that the cutting tool is sharp and suitable for brake drum turning.
• Measuring tools: You will need a micrometer or a dial indicator to measure the drum’s thickness after turning to ensure it is within the manufacturer’s specifications.
• Safety equipment: Always wear protective goggles and gloves to prevent any injuries while operating the lathe machine.

Step-by-step Guide

Here is a step-by-step guide to turning brake drums:

1. Secure the lathe machine: Ensure the lathe machine is properly fixed to a stable surface to prevent any movement during operation.
2. Select the appropriate brake drum adapter: Choose the adapter that matches the size and type of brake drum you are going to turn. Attach the adapter securely to the lathe machine.
3. Mount the brake drum: Install the brake drum on the adapter, ensuring it is centered and tightly secured using the proper mounting bolts or clamps.
4. Set the cutting tool: Adjust the cutting tool to the correct depth and position, ensuring that it will remove the desired amount of material from the drum’s surface.
5. Turn the drum: Start the lathe machine and slowly rotate the drum while engaging the cutting tool. Allow the machine to complete several passes to achieve a smooth and even surface.
6. Measure the drum: After turning, use a micrometer or dial indicator to measure the drum’s thickness. Ensure it meets the manufacturer’s specifications.
7. Finish the process: If the drum passes the measurements, remove it from the lathe machine and clean any metal shavings or debris. Reinstall the drum on the vehicle along with new brake shoes.

By following these steps, you can effectively turn your brake drums, restoring their performance and extending their lifespan. Remember, if you are unsure or inexperienced, it is recommended to consult a professional mechanic to ensure the process is done correctly.
