Drum to Disc Brake Conversion: A Step-by-Step Guide
Upgrading your vehicle's braking system from drum brakes to disc brakes is a significant improvement in stopping power and overall safety. While it's a more involved project than a simple brake pad change, the enhanced performance and feel are well worth the effort. This comprehensive guide will walk you through the process, offering a step-by-step approach to a successful drum to disc brake conversion. Disclaimer: This guide provides general information. Always consult your vehicle's service manual and relevant safety regulations before undertaking any brake work. Improper installation can lead to serious injury or death.
Why Convert to Disc Brakes?
Before diving into the specifics, let's understand why many choose to upgrade from drum brakes to disc brakes. Disc brakes offer several key advantages:
- Superior Stopping Power: Disc brakes provide significantly better stopping power, especially in wet or adverse weather conditions. The larger surface area of the disc and the direct clamping action of the caliper result in quicker, more effective braking.
- Improved Fade Resistance: Disc brakes are less prone to brake fade under heavy use. This is crucial for performance driving or frequent braking in demanding situations.
- Better Heat Dissipation: The open design of disc brakes allows for better heat dissipation, reducing the risk of brake failure due to overheating.
- Enhanced Pedal Feel: Disc brakes generally offer a firmer, more responsive pedal feel, providing the driver with better control and feedback.
Planning Your Drum to Disc Conversion
A successful conversion requires careful planning. Here’s what you need to consider:
- Choosing the Right Kit: Several aftermarket kits are available specifically designed for drum-to-disc conversions on various vehicle models. Research and choose a reputable brand offering a complete kit tailored to your vehicle's year, make, and model. Ensure the kit includes everything you'll need: calipers, rotors, brackets, lines, pads, and hardware.
- Gathering Tools: You'll need a comprehensive set of tools, including wrenches, sockets, jack stands, a torque wrench (crucial for brake system safety), brake cleaner, and potentially a wheel bearing press depending on the kit and your vehicle.
- Safety Precautions: Always work in a well-ventilated area. Wear safety glasses and gloves. Never work under a vehicle supported only by a jack – use jack stands.
Step-by-Step Conversion Process
The exact steps will vary depending on the kit and your vehicle, but this provides a general overview:
- Vehicle Preparation: Securely raise and support your vehicle on jack stands. Remove the wheel to access the drum brake assembly.
- Drum Brake Removal: Carefully remove the wheel cylinder, brake shoes, and drum. Take note of the order of components and any special considerations during disassembly.
- Hub Preparation: Clean and inspect the hub assembly for any damage. You may need to clean or lightly machine the hub surface to ensure a proper fit for the new rotor.
- Mounting the Disc Brake Kit: This is where the specific instructions for your kit become crucial. Carefully follow the manufacturer's instructions for mounting the caliper brackets, rotors, and calipers. Pay close attention to torque specifications for all bolts.
- Brake Line Installation: Connect the new brake lines to the calipers and bleed the system thoroughly to remove any air bubbles. This step is critical for proper brake function.
- Brake Pad Installation: Install the new brake pads into the calipers according to the manufacturer's instructions.
- Bleeding the Brakes: Properly bleeding the brake system is essential to remove any air that may have entered during the installation process. Use a brake bleeder kit and follow the correct bleeding sequence for your vehicle.
- Testing and Adjustment: After installation, carefully test the brakes in a safe, controlled environment. Adjust the parking brake if necessary, and ensure the brakes are functioning correctly before driving the vehicle.
