How to Change Rear Drum Brakes on a 2007 Silverado

Changing the rear drum brakes on your 2007 Chevrolet Silverado can seem like a daunting task, but with the right tools and a bit of know-how, you can do it yourself. This guide will walk you through the necessary steps to safely and effectively replace your drum brakes, ensuring your truck remains safe and reliable on the road.

Tools and Materials Needed

Before you begin, gather the following tools and materials

- Jack and jack stands - Lug wrench - Drum brake tool kit (including spring pullers) - New brake shoes - New drum (if needed) - Brake cleaner - Lubricant (high-temperature wheel bearing grease) - Screwdriver - Safety goggles and gloves

Safety First

Before starting any mechanical work, ensure you’re in a well-ventilated area and wearing safety goggles and gloves. Always engage the parking brake and make sure the vehicle is on a flat surface.

Step 1 Remove the Wheel

1. Loosen the Lug Nuts Before jacking up the truck, use the lug wrench to slightly loosen the lug nuts on the rear wheels. 2. Jack Up the Vehicle Using your jack, lift the rear of the Silverado until it is high enough to place jack stands securely under the frame. Ensure the truck is stable before proceeding. 3. Remove the Wheel Fully remove the loosened lug nuts and take off the wheel to expose the drum brake assembly.

1. Check for Damage Inspect the drum for any cracks, grooves, or excessive wear. If it’s damaged, you'll need to replace it. 2. Remove the Brake Drum If the drum doesn’t slide off easily, you might need to tap it with a hammer or use a brake drum puller. Once removed, look at the condition of the brake shoes and hardware.

Step 3 Remove Old Brake Shoes

1. Take Notes It’s a good idea to take pictures of the brake assembly before disassembly. This will help you remember the correct configuration when installing new parts. 2. Detach Hardware Using the drum brake tool kit, remove the springs, adjusters, and any other hardware securing the brake shoes. Be careful as the springs can be under tension. 3. Remove the Shoes Gently pull off the old brake shoes from the backing plate.

Step 4 Install New Brake Shoes

1. Prepare the New Shoes Compare the new shoes with the old ones to ensure they are the correct size. 2. Attach New Shoes Position the new brake shoes onto the backing plate. Follow the same configuration you noted during disassembly. Reattach the hardware and springs, ensuring they are secured tightly.

Step 5 Reinstall the Brake Drum

1. Check Alignment Make sure the brake shoes are aligned properly before reinstalling the drum. 2. Install the Drum Slide the drum back onto the hub. If it doesn’t fit, adjust the shoes using the adjusting screw until it does. 3. Spin the Drum Make sure the drum turns freely without dragging.

Step 6 Reassemble and Test

1. Reattach the Wheel Place the wheel back on and hand-tighten the lug nuts. Lower the vehicle and then fully tighten the lug nuts to the manufacturer’s specifications. 2. Test Brake Functionality Before driving, press the brake pedal several times to seat the brake shoes against the drum. Finally, test your brakes in a safe area to ensure everything is functioning correctly.

Conclusion

Changing the rear drum brakes on a 2007 Silverado requires some time and effort, but it’s a rewarding DIY project that can save you money. Regular maintenance and timely replacement of your brake components will ensure the safety and performance of your vehicle. If you’re unsure at any step, don’t hesitate to consult the vehicle’s service manual or a professional mechanic. Happy driving!
