Introduction

This tutorial will guide you through the process of replacing the rear drum brakes on a 2012 to 2015 Chevy Sonic with either a 1.8L or 1.4L engine. This step-by-step guide is designed to help you perform this task safely and efficiently, even if you’re not an experienced mechanic.

Step 1: Gather Necessary Tools and Parts

Before starting, ensure you have the following tools and parts ready:

• Tools:
  • Screwdrivers
  • Pliers (preferably locking pliers)
  • Jack and jack stands
  • Torque wrench
• Parts:
  • New brake drums
  • New brake pads (Power Stop Auto Specialties ceramic pads)
  • New rotors (Three Best Oh rotors)

Step 2: Prepare the Vehicle

1. Park the vehicle on a flat surface.
2. Engage the parking brake.
3. Use a jack to lift the rear of the vehicle and secure it on jack stands.

Step 3: Remove the Wheel

1. Loosen the lug nuts of the rear wheel before lifting the vehicle.
2. Once elevated, fully remove the lug nuts and take off the wheel.

Step 4: Remove the Old Brake Drum

1. Inspect the brake drum for screws or clips holding it in place and remove them.
2. Gently pull the drum off. If it’s stuck, you may need to tap it lightly with a hammer to free it.

Step 5: Replace the Brake Shoes

1. Remove the old brake shoes. Note how they are positioned for reinstallation.
2. Install the new brake shoes, ensuring they are aligned correctly.
3. Pay attention to the orientation of the springs; improper installation will make it difficult to reassemble.

Step 6: Reinstall the Brake Drum

1. Place the new brake drum over the installed shoes.
2. Ensure that everything fits snugly and rotate the drum to check for any obstructions.

Step 7: Install New Rotor

1. Place the new rotor onto the hub.
2. Secure it using the retaining screws or clips that were removed earlier.

Step 8: Reattach the Wheel

1. Align the wheel and place it back onto the hub.
2. Hand-tighten the lug nuts, then lower the vehicle from the jack stands.
3. Use a torque wrench to tighten the lug nuts to 80 foot-pounds.

Step 9: Test the Brakes

1. Before driving, pump the brake pedal a few times to ensure the new shoes and drum are properly seated.
2. Test drive the vehicle at low speeds to confirm the brakes are functioning correctly.

Conclusion

Replacing the rear drum brakes on a Chevy Sonic can be a straightforward process if you follow these steps carefully. Always remember to use proper tools and safety equipment, such as jack stands.
