Mastering the Art of Adjusting Ford Focus Rear Drum Brakes: A Step-by-Step Guide

Are you experiencing a grinding noise or a spongy brake pedal in your Ford Focus? These could be signs of worn-out or improperly adjusted rear drum brakes. While modern vehicles often feature disc brakes on all four wheels, the Ford Focus, especially older models, still utilizes drum brakes at the rear. Knowing how to adjust Ford Focus rear drum brakes is a valuable skill for any car owner, as it can save you money on costly repairs and ensure optimal braking performance.

This comprehensive guide will walk you through the process of adjusting your Ford Focus rear drum brakes, step by step. We’ll cover everything from identifying the components to troubleshooting common issues, empowering you to tackle this task with confidence.

Understanding the Basics of Rear Drum Brakes

Before diving into the adjustments, let’s understand how rear drum brakes work. These brakes consist of a drum, brake shoes, and a wheel cylinder. When you press the brake pedal, hydraulic pressure is applied to the wheel cylinder, which pushes the brake shoes outward against the inner surface of the drum. The friction generated between the shoes and the drum slows down the vehicle.

Why Adjust Your Rear Drum Brakes?

Properly adjusted rear drum brakes are crucial for:

• Optimal Braking Performance: Loose brake shoes can lead to a spongy pedal and reduced braking efficiency.
• Preventing Wear and Tear: Overly tight brake shoes can cause premature wear on the brake shoes and drum, leading to more frequent replacements.
• Minimizing Noise: Improperly adjusted brakes can create a grinding or squealing noise during braking.

Tools You’ll Need

To adjust your Ford Focus rear drum brakes, you’ll need the following tools:

• Jack and Jack Stands: To lift the car safely.
• Wheel Wrench: To remove the rear wheels.
• Flathead Screwdriver: To adjust the brake shoes.
• Socket Wrench: To remove the brake drum.
• Torque Wrench: To tighten the lug nuts to the correct specifications.
• Brake Cleaner: To clean the brake components.
• Gloves: To protect your hands from grease and dirt.

Step-by-Step Guide to Adjusting Ford Focus Rear Drum Brakes

Here’s how to adjust your Ford Focus rear drum brakes:

1. Park the Vehicle on a Level Surface: Engage the parking brake and chock the front wheels to prevent the vehicle from rolling.
2. Raise the Rear of the Vehicle: Use a jack to lift the rear of the vehicle and secure it with jack stands. Make sure the jack stands are placed on solid ground.
3. Remove the Rear Wheels: Use a wheel wrench to loosen the lug nuts, then remove the rear wheels.
4. Inspect the Brake Components: Visually inspect the brake shoes, drum, and wheel cylinder for any signs of wear, damage, or fluid leaks.
5. Locate the Adjustment Star Wheel: The adjustment star wheel is located on the back of the brake drum, near the backing plate. It has a series of notches that allow you to adjust the brake shoes.
6. Adjust the Brake Shoes: Using a flathead screwdriver, turn the adjustment star wheel clockwise to tighten the brake shoes. Turn it counterclockwise to loosen them.
7. Test the Brake Pedal: Lower the vehicle and test the brake pedal. The pedal should feel firm and responsive. If it’s still spongy, repeat steps 5 and 6 until the desired firmness is achieved.
8. Reassemble the Brakes: Once you’re satisfied with the adjustment, reinstall the brake drum, wheels, and lug nuts. Tighten the lug nuts to the manufacturer’s specifications.
9. Lower the Vehicle: Remove the jack stands and lower the vehicle to the ground.

Troubleshooting Common Issues

If you’re having trouble adjusting your rear drum brakes, here are some common issues and solutions:

• Stuck Adjustment Star Wheel: If the adjustment star wheel is stuck, it may need to be cleaned or lubricated. Use a brake cleaner to remove any rust or debris.
• Worn Brake Shoes: Worn brake shoes may need to be replaced. If they are excessively worn, they may not be able to be adjusted properly.
• Damaged Brake Drum: A damaged brake drum may need to be replaced. A cracked or warped drum can cause uneven braking and noise.

Final Touches: Ensuring Safety and Performance

After adjusting your rear drum brakes, it’s crucial to do a final check:

• Test Drive: Take your Ford Focus for a test drive and apply the brakes several times. Make sure the pedal feels firm and the brakes are engaging smoothly.
• Check for Leaks: Inspect the brake system for any signs of fluid leaks. If you notice any leaks, address them immediately.
• Professional Inspection: For added peace of mind, consider taking your vehicle to a qualified mechanic for a professional inspection of your brakes.

A Farewell to Faded Braking: Your Ford Focus is Ready to Roll

By following these steps and addressing any potential issues, you’ve successfully mastered the art of adjusting Ford Focus rear drum brakes. You’ve gained a valuable skill that will save you money and ensure optimal braking performance for your vehicle. Remember, regular maintenance is key to keeping your brakes in top condition.
