How to Make a Brake Drum Puller

Brake drum pullers are essential tools for anyone involved in automotive repairs, particularly when working on drum brake systems. These tools help to remove the brake drum from the hub, which can often be a challenging task due to rust, wear, or damage. Instead of purchasing an expensive commercial tool, you can make your own brake drum puller with some basic materials and tools. This guide will walk you through the process step by step.

Materials Needed

To create your own brake drum puller, you will need the following materials 1. Heavy-duty steel plate This will serve as the base of your puller. It should be thick enough to withstand the force applied during the pulling process. 2. Three 7-inch bolts These will be used to attach the puller to the brake drum. 3. Three washers These help distribute the force over a larger area of the drum, preventing damage. 4. One heavy-duty central bolt (about 8 inches long) This will serve as the main puller bolt. 5. Two nuts These will secure the central bolt in place. 6. Drill and drill bits For making the necessary holes in the steel plate. 7. Wrench set For tightening and loosening the bolts.

Step-by-Step Instructions

1. Cut the Steel Plate Begin by cutting your heavy-duty steel plate into a circle that is slightly larger than the diameter of your brake drum. A diameter of about 10 to 12 inches typically works well. This will be the main body of your puller.

2. Drill Holes for the Bolts Using a drill, make three evenly spaced holes around the edge of the steel plate. Each hole should accommodate the 7-inch bolts. The holes should be positioned so that when the puller is attached to the brake drum, the bolts extend outward and can anchor against it.

3. Prepare the Central Bolt Slot In the center of your steel plate, drill a single hole slightly larger than the diameter of your heavy-duty central bolt. This hole is critical as it will allow you to screw the bolt downward into the brake drum.

4. Assemble the Puller Insert the three 7-inch bolts through the holes you created earlier. Place a washer on each bolt and secure them from the underside with a nut. Tighten these nuts well, ensuring the bolts are firmly anchored to the steel plate.

5. Attach the Central Bolt Position your central bolt through the hole at the center of the steel plate. Add a washer and a nut on the top of the steel plate and tighten it down. This bolt will be the mechanism that pulls the brake drum off as you turn it.

6. Test Your Puller Before using your new puller, it’s wise to test it on a scrap drum or similar material to ensure it is functioning properly. Make any necessary adjustments to the size of the bolts or the steel plate.

7. Using the Puller When you're ready to use the puller, position the tool onto the brake drum, ensuring the three outer bolts are making contact with the drum surface. Gradually turn the central bolt clockwise while keeping an eye on the entire setup to ensure nothing slips or misaligns.

Conclusion

Making your own brake drum puller can save you money and provide you with an effective tool for your automotive needs. By following these steps and using the appropriate materials, you can create a reliable puller that will help you tackle drum brake jobs with ease. Always remember to prioritize safety by wearing protective gear and ensuring that your setup is stable before force is applied. Happy repairing!
