Converting Drum Brakes to Disc Brakes A Step-by-Step Guide for Beginners

How to Change Drum Brakes into Disc Brakes

Drum brakes have been a standard feature in many vehicles for decades, but as automotive technology has evolved, disc brakes have become increasingly popular due to their enhanced performance and reliability. If you’re considering upgrading your car from drum brakes to disc brakes, this article will guide you through the process, making it easier to understand the steps involved and what you will need.

1. Understanding the Advantages of Disc Brakes

Before diving into the conversion process, it's important to recognize why many car enthusiasts prefer disc brakes. Disc brakes are generally more efficient at dissipating heat, which can lead to improved braking performance, especially during intensive usage, such as in emergency stops or during spirited driving. They are also less susceptible to water and mud issues, leading to more consistent stopping power in various weather conditions.

2. Gather Necessary Tools and Parts

To successfully convert from drum brakes to disc brakes, you’ll need several tools and parts. Here’s a basic list

Tools

- Jack and jack stands - Socket set and wrenches - Brake cleaner - Torque wrench - Screwdriver set - Pliers - Hammer

Parts

- Disc brake conversion kit (specific to your vehicle model) - New brake rotors - Calipers - Brake pads - Brake lines (may need to be replaced)

3. Preparing for the Conversion

Before you start the conversion, ensure you have a clean, safe workspace. Park your vehicle on a level surface, engage the parking brake, and loosen the lug nuts before lifting the car with a jack. Once elevated, remove the rear wheels to access the drum brakes.

4. Removing the Drum Brakes

To convert to disc brakes, you'll first need to remove the old drum brake assembly

1. Remove the Drum After taking off the wheel, remove the drum. This might involve loosening adjustment screws or tapping it lightly with a hammer to free it from rust and brake dust.

2. Disconnect the Brake Components Disconnect the brake lines from the wheel cylinder, and then remove the spring and shoe assembly carefully. Be cautious, as the springs can be under tension.

3. Completely Remove the Backing Plate Unscrew the backing plate from the axle to make way for the new disc brake setup.

5. Installing Disk Brake Components

Once you have removed all components of the drum brakes, you can proceed with installing the disc brakes

1. Install the New Brake Rotor Place the new brake rotor onto the hub and fasten it securely with the proper lug nuts. Make sure it’s seated correctly.

2. Attach the Caliper Bracket Most disc brake kits come with a caliper bracket. Install this to the vehicle’s axle in accordance with the provided instructions.

3. Install Calipers and Brake Pads Secure the calipers to the bracket and insert the brake pads. Make sure they’re properly aligned and seated.

4. Connect Brake Lines If your conversion kit requires new brake lines, ensure that all connections are tight and free from leaks.

6. Finishing Up and Testing

After installing the disc brakes, it’s crucial to bleed the brake system to remove any air bubbles that could affect braking performance. Once bled, replace the wheels and lower the vehicle.

Testing Before driving on public roads, conduct a thorough test in a safe area. Ensure that the brakes respond effectively and the stopping power is adequate.

Conclusion

Converting from drum brakes to disc brakes can enhance your vehicle's performance significantly. While the conversion process may seem daunting, with the right tools, parts, and patience, it can be accomplished. Always prioritize safety and consider consulting with a professional if you’re unsure about any step. With your new disc brakes, you’ll enjoy improved braking performance and confidence on the road.
