Understanding Brake Drum Resurfacing
Brake drums play a crucial role in your vehicle’s braking system, especially in older vehicles equipped with drum brakes. These drums provide a surface for the brake shoes to press against, creating friction and slowing down the vehicle. Over time, brake drums can wear out due to heat, friction, and general use.
Brake drum resurfacing involves removing a thin layer of damaged metal from the drum’s surface to create a smoother and more consistent braking surface. This process ensures better contact between the brake shoes and the drum, resulting in improved braking performance.
AutoZone’s Services
Unfortunately, AutoZone does not offer brake drum resurfacing. However, there are other auto parts chains that do provide this service. For example:
- O’Reilly Auto Parts: O’Reilly offers in-store brake drum and rotor resurfacing. You can bring in your used drums or rotors, and their parts professionals will measure them using a micrometer. If there’s enough material left, they can resurface them¹.
- Pep Boys: Pep Boys also provides brake rotor resurfacing services. If your brake rotors are still within safe limits, they can be resurfaced to restore their performance.
Signs You Might Need Brake Drum Resurfacing
Here are some signs that your brake drums may need resurfacing:
- Uneven Braking: If you experience uneven braking or notice your vehicle pulling to one side during braking, it could be due to worn or uneven brake drums.
- Vibrations or Pulsations: Warped or damaged brake drums can cause vibrations in the steering wheel or pulsations in the brake pedal when you apply the brakes.
- Glazing: Glazing occurs when excessive heat causes the brake pad friction material to stick to the drum’s surface. This results in poor braking performance.
Remember that resurfacing is not always the best solution. If your brake drums have significant damage, it’s essential to replace them. Regular maintenance and inspection can help prolong the life of your braking components.
In summary, while AutoZone doesn’t offer brake drum resurfacing, consider visiting other auto parts stores like O’Reilly or Pep Boys for this service. Keeping your braking system in top condition ensures your safety on the road!
