Your car’s brakes are its most crucial safety system, responsible for bringing your vehicle to a safe stop. While disc brakes have become increasingly popular, drum brakes are still found on many vehicles, particularly older models and rear axles. Properly functioning drum brakes rely on a complex interplay of components, and a crucial part of this system is the drum brake hardware kit. This kit contains all the essential parts that keep the brake mechanism working smoothly and efficiently. Understanding how to install a drum brake hardware kit is a valuable skill for any car owner, allowing you to maintain your vehicle’s safety and potentially save money on costly repairs.
Understanding Drum Brake Hardware Kits
Drum brake hardware kits are essential for the proper functioning of drum brake systems. They typically include a variety of components, each playing a specific role in the braking process. These components can vary slightly depending on the make and model of your vehicle, but common items found in a drum brake hardware kit include:
- Brake Shoes: These are the friction surfaces that press against the brake drum to create the stopping force.
- Adjuster Mechanism: This mechanism automatically adjusts the clearance between the brake shoes and the drum, ensuring proper braking performance.
- Springs: Various springs help to maintain the tension on the brake shoes, return them to their original position after braking, and assist in the adjustment process.
- Wheel Cylinders: These cylinders contain the brake fluid and apply pressure to the brake shoes when the brake pedal is pressed.
- Hardware Clips and Pins: These small components secure the brake shoes and other hardware in place.
Regularly inspecting and replacing worn or damaged hardware components is crucial for maintaining safe and reliable braking performance. Neglecting these components can lead to uneven braking, reduced stopping power, and potential brake failure.

Step-by-Step Installation Guide
Now that you have the necessary tools and materials, let’s walk through the process of installing your drum brake hardware kit. Remember to always consult your vehicle’s repair manual for specific instructions and torque specifications.
1. Prepare the Vehicle
Park your vehicle on a level surface and engage the parking brake. Loosen the lug nuts on the wheel where you’ll be working. Jack up the vehicle and securely support it on jack stands. Remove the wheel.
2. Remove the Drum Brake Assembly
Inspect the drum brake assembly for any signs of damage or wear. Remove the brake drum by carefully tapping it with a hammer. Be gentle to avoid damaging the drum or the brake backing plate. Once the drum is removed, you can access the brake shoes, adjuster mechanism, and other hardware components. (See Also: What Thickness Are New Brake Pads? Standard Dimensions Revealed)
3. Inspect and Replace Worn Components
Carefully examine all the components within the drum brake assembly. Pay attention to the brake shoes, springs, adjuster mechanism, and wheel cylinders. Replace any worn or damaged components with new parts from your drum brake hardware kit. Ensure that all components are properly lubricated with brake grease.
4. Install the New Hardware
Follow the instructions provided with your drum brake hardware kit to install the new components. Pay close attention to the placement and orientation of each part. Use the correct tools to tighten all bolts and nuts to the specified torque. Remember to lubricate all contact points with brake grease to ensure smooth operation.
5. Adjust the Brake Shoes
The adjuster mechanism is responsible for automatically adjusting the clearance between the brake shoes and the drum. Follow the instructions in your vehicle’s repair manual to properly adjust the brake shoes. This typically involves turning a star wheel or using a special tool to adjust the tension on the brake shoes.
6. Reassemble the Drum Brake Assembly
Once the brake shoes are adjusted, carefully reassemble the drum brake assembly. Slide the brake drum back onto the brake backing plate and ensure it is properly seated. Tighten the lug nuts on the wheel.
7. Bleed the Brakes
After installing the new drum brake hardware kit, it’s essential to bleed the brakes to remove any air trapped in the brake lines. This will ensure that the brakes operate properly and have full stopping power. Consult your vehicle’s repair manual for specific instructions on bleeding the brakes.
Testing and Maintenance
After completing the installation, test the brakes thoroughly in a safe area. Start by applying gentle pressure to the brake pedal, gradually increasing the pressure until the vehicle comes to a complete stop. Listen for any unusual noises or feel for any vibrations in the brake pedal. If everything feels normal, you can drive the vehicle cautiously and test the brakes in various situations.

Frequently Asked Questions
How often should I replace my drum brake hardware kit?
There is no set mileage interval for replacing drum brake hardware kits. However, it’s generally recommended to inspect the components at least every 2 years or 24,000 miles. If you notice any signs of wear, damage, or excessive noise, it’s best to replace the kit sooner rather than later.
What are the signs of worn drum brake hardware?
Some common signs of worn drum brake hardware include: grinding or squealing noises when braking, a spongy or soft brake pedal, pulling to one side when braking, and uneven brake wear. (See Also: Is Wagner Brake Pads Good? Worth The Hype)
Can I install a drum brake hardware kit myself?
Yes, installing a drum brake hardware kit is a relatively straightforward DIY project. However, it’s important to have basic mechanical skills and the necessary tools. If you’re not comfortable working on your brakes, it’s always best to consult a qualified mechanic.
What type of brake fluid should I use?
Consult your vehicle’s owner’s manual to determine the recommended type of brake fluid. Using the wrong type of brake fluid can damage your braking system.
How do I know if my brakes are properly adjusted?
