However, if you're determined to do it yourself, here's a *general* outline. This is not a complete, step-by-step guide, and variations exist depending on the specific year and model of your Ford Focus. Always consult a repair manual specific to your vehicle's year and model.
Tools you will likely need:
* Jack and jack stands (essential for safety!)
* Wheel chocks
* Lug wrench
* Socket wrench set (various sizes)
* Brake shoe spring pliers (several types are available)
* C-clamp (potentially for compressing the wheel cylinder)
* Wire brush
* Brake cleaner
* New brake shoes (ensure they are the correct part number for your vehicle)
* Grease (suitable for brake components)
* Possibly a drum removal tool (depending on how stubborn the drum is)
* Torque wrench (to properly tighten lug nuts)
General Steps (Highly Simplified and Not Exhaustive):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the wheels that are *not* being worked on. Raise the vehicle safely using a jack and secure it with jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Brake Drum: This can be tricky. Sometimes it just slides off; other times, it's rusted on. You may need to gently tap it with a rubber mallet while rotating it back and forth. A drum puller tool can be helpful if it's stuck.
4. Inspect Components: Carefully inspect the brake shoes, wheel cylinder, and other components for wear, damage, or leaks. If anything is damaged, replace it.
5. Remove the Old Brake Shoes: This is where the spring pliers come in. There are several springs holding the shoes in place. Use the appropriate pliers to carefully remove the springs and then the old brake shoes. Note how the springs and shoes are arranged – you'll need to replicate this during reassembly.
6. Clean the Drum and Shoes: Thoroughly clean the brake drum and the new brake shoes with a wire brush and brake cleaner.
7. Install the New Brake Shoes: Install the new brake shoes, making sure they are correctly positioned and seated. Re-attach the springs using the spring pliers. This step is critical; incorrect installation will lead to brake failure.
8. Adjust the Brake Shoes: This is usually done by a self-adjuster mechanism within the braking system. However, there may be a manual adjustment. Refer to your repair manual.
9. Reinstall the Brake Drum: Carefully reinstall the brake drum, ensuring it's seated properly.
10. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts to the manufacturer's specified torque.
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Test the Brakes: Test the brakes carefully and gently before driving the vehicle at normal speeds. If the brake pedal feels spongy or the braking performance is poor, there may be an issue that needs further investigation by a professional.
Disclaimer: This is a simplified overview. Improper brake work can be extremely dangerous. If you are not comfortable or confident in performing this repair, take your vehicle to a qualified mechanic. They have the proper tools, expertise, and knowledge to ensure the job is done correctly and safely. Consulting a repair manual specific to your Ford Focus is crucial for detailed instructions and safety precautions.
