Introduction

This tutorial provides a detailed, step-by-step guide on how to replace drum brakes, specifically for the rear brakes of a 2009 VW Polo 9N. Understanding the process is essential for maintaining your vehicle's braking system and ensuring safety on the road.

Step 1: Gather Your Tools and Materials

Before starting the replacement process, ensure you have the following tools and materials ready:

• Tools Needed

  • Wrench set
  • Screwdrivers (flat and Phillips)
  • Brake drum puller
  • Pliers
  • Torque wrench
  • Rubber mallet
  • Brake cleaner
  • Safety goggles and gloves

• Materials Needed

  • New brake shoes
  • New brake drums (if necessary)
  • Brake grease
  • Replacement springs (if needed)

Step 2: Prepare the Vehicle

Follow these steps to safely prepare your vehicle for the brake replacement:

1. Park the vehicle on a flat surface.
2. Engage the parking brake.
3. Loosen the lug nuts on the rear wheels slightly while the vehicle is still on the ground.
4. Raise the rear of the vehicle using a jack and secure it with jack stands.
5. Remove the rear wheels to access the brake drums.

Step 3: Remove the Brake Drum

To access the brake components, you need to remove the brake drum:

1. Inspect the brake drum for any retaining screws and remove them if present.
2. If the drum is stuck, gently tap it with a rubber mallet to loosen it.
3. Once loose, pull the drum straight off. If it doesn't come off easily, use a brake drum puller.

Step 4: Inspect and Remove Old Brake Components

Now it's time to inspect and remove the existing brake shoes:

1. Examine the condition of the brake shoes. If they are worn out or damaged, they need to be replaced.
2. Take note of the spring and linkage configuration as you'll need to replicate this during reinstallation.
3. Remove the old brake shoes by taking off any retaining springs and clips using pliers.

Step 5: Install New Brake Shoes

Follow these steps to install the new brake shoes:

1. Apply brake grease to the contact points of the new shoes.
2. Position the new shoes in place, ensuring they align with the brake assembly.
3. Reattach the springs and clips in the same manner as they were removed. Use a spring tool if necessary for added leverage.

Step 6: Reassemble the Brake Drum

After installing the new brake shoes, reassemble the brake drum:

1. Carefully slide the brake drum back onto the wheel hub.
2. Ensure that it rotates freely without binding against the shoes.
3. If applicable, reinstall any retaining screws to secure the drum in place.

Step 7: Reinstall the Wheel

After securing the brake drum, follow these steps to reinstall the wheel:

1. Place the wheel back onto the hub and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground using the jack.
3. Once the vehicle is on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.

Conclusion

Replacing drum brakes on your vehicle is a manageable task with the right tools and guidance. Always ensure safety precautions are taken, such as wearing gloves and goggles. After completing the replacement, it's advisable to test drive the vehicle at low speeds to ensure proper function before returning to normal driving conditions. Regular maintenance of your braking system helps ensure your safety and extends the lifespan of your vehicle's components.
