Signs of Worn Brake Drums and How to Replace Them

Brake drums are a crucial component of a vehicle’s braking system, particularly in rear-wheel setups. Over time, these drums can wear out, leading to decreased braking efficiency and potential safety hazards. Recognizing the signs of worn brake drums and understanding the replacement process can ensure optimal vehicle performance and safety.

Common Signs of Worn Brake Drums

Identifying issues with brake drums early can prevent more severe problems down the road. Here are some common indicators:

1. Unusual Noises

• Grinding Sounds: A metallic grinding noise often indicates that the brake shoes have worn down completely, causing metal-to-metal contact with the drum.

• Squealing: Persistent squealing noises, especially when braking lightly, may suggest that the brake shoes are worn or contaminated.

2. Reduced Braking Performance

If your vehicle takes longer to stop or requires more effort to apply the brakes, it could be due to worn brake drums or shoes.

3. Vibrations or Pulsations

Feeling vibrations or pulsations through the brake pedal or steering wheel during braking can indicate that the brake drum is warped or out of round.

4. Pulling to One Side

If the vehicle pulls to one side during braking, it may be due to uneven wear on the brake drums or shoes.

5. Visual Damage

Inspecting the brake drums for visible cracks, deep grooves, or scoring can reveal wear that affects braking efficiency.

Step-by-Step Guide to Replacing Brake Drums

Replacing brake drums is a task that can be undertaken by those with basic mechanical skills. Here’s a general guide:

Tools and Materials Needed

• Jack and jack stands

• Lug wrench

• Brake cleaner

• Socket set

• Brake drum puller (if necessary)

• Replacement brake drums and shoes

Procedure

1. Preparation

   • Park the vehicle on a level surface and engage the parking brake.

   • Loosen the lug nuts on the rear wheels slightly.

   • Lift the vehicle using a jack and secure it with jack stands.

   • Remove the wheels to access the brake drums.

2. Inspecting the Brake Drums

   • Look for signs of wear such as cracks, deep grooves, or scoring.

   • Measure the drum’s diameter to ensure it hasn’t exceeded the manufacturer’s specifications.

3. Removing the Brake Drums

   • If the drum is stuck, use a brake drum puller to remove it.

   • Clean the area with brake cleaner to remove dust and debris.

4. Replacing the Brake Shoes

   • Remove the old brake shoes and inspect the hardware for wear.

   • Install the new brake shoes, ensuring they are properly aligned and tensioned.

5. Installing the New Brake Drums

   • Place the new brake drums onto the wheel hub.

   • Ensure they rotate freely without any binding.

6. Reassembling

   • Reinstall the wheels and tighten the lug nuts.

   • Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

7. Testing

   • Pump the brake pedal to seat the brake shoes.

   • Test drive the vehicle at low speeds to ensure proper braking function.

Maintenance Tips

• Regular Inspections: Check the brake drums and shoes for wear every 12,000 to 16,000 miles.

• Proper Bedding-In: After installation, perform a proper bedding-in procedure to ensure optimal performance.

• Avoid Overloading: Excessive weight can cause premature wear on brake components.

• Use Quality Parts: Always replace brake components with high-quality, compatible parts.
