How to Resurface Brake Drums

Resurfacing brake drums is an important maintenance task that can help ensure your vehicle's braking system functions efficiently. Over time, brake drums can become worn, warped, or damaged, leading to decreased performance and safety. Instead of replacing the whole drum, resurfacing can restore its functionality while saving money. Here’s a step-by-step guide on how to properly resurface brake drums.

Materials Needed - Brake drum resurfacing machine - Torque wrench - Brake cleaner - Safety goggles - Gloves - Measuring tool (caliper) - Sandpaper (fine-grit) - Clean rags

Step 1 Remove the Wheel Start by safely lifting the vehicle with a jack and securing it with jack stands

. Remove the wheel to gain access to the brake assembly.

Step 2 Remove the Brake Drum Next, remove the brake drum from the hub. If it’s stuck, gently tap it with a rubber mallet to break it loose. Be careful not to damage surrounding components.

Step 3 Inspect the Brake Drum Before resurfacing, there’s an essential inspection process. Use a caliper to measure the drum's thickness. If it’s below the manufacturer’s specifications, replacement is necessary. Look for any visible cracks or severe wear, which also indicates that resurfacing is not advisable.

Step 4 Resurface the Drum Use a brake drum resurfacing machine to smooth out the drum's surface. Align the drum according to the machine's instructions and set the appropriate cut depth. Typically, a light cut is sufficient to remove grooves and imperfections while maintaining the drum's structural integrity.

Step 5 Clean the Drum After resurfacing, clean the drum thoroughly with brake cleaner to remove any dust or debris. This step is crucial as it helps prevent contamination when reassembling the brake system.

Step 6 Reinstall the Drum Once cleaned, carefully reinstall the brake drum onto the hub. Ensure it fits properly and is seated correctly.

Step 7 Reattach the Wheel Put the wheel back on and hand-tighten the lug nuts. Lower the vehicle and make sure it's stable before fully tightening the lug nuts with a torque wrench to the manufacturer’s specifications.

Conclusion Resurfacing brake drums can be a straightforward process if you have the right tools and knowledge. Regular maintenance of your brakes is crucial for safety, performance, and longevity. If you are unsure about any step or lack the necessary equipment, it is advisable to consult or hire a professional mechanic. With proper care, your braking system will operate smoothly, enhancing your driving experience and safety on the road.
