How to Convert Drum Brakes to Disc Brakes
Converting drum brakes to disc brakes is a popular modification for many car enthusiasts and those looking to improve their vehicle's braking performance. The upgrade can enhance stopping power, reduce brake fade, and provide a more consistent pedal feel. If you're considering this modification, this article will guide you through the process, its benefits, and some important considerations.
Understanding the Basics
Drum brakes and disc brakes operate on different principles. Drum brakes use a set of shoes that expand against the inside of a drum to create friction, while disc brakes use calipers to squeeze brake pads against a rotating disc (or rotor). Disc brakes typically offer better performance, especially in high-speed or heavy-duty situations, as they dissipate heat better and provide more reliable braking.
Benefits of Conversion
1. Performance Disc brakes usually perform better than drum brakes. They have a larger surface area, which translates to better heat dissipation and less brake fade during intense braking. 2. Maintenance Disc brakes are generally easier to maintain and replace than drum brakes. They’re more accessible and require fewer tools for servicing.
3. Consistency Disc brakes provide a more consistent feel under varied conditions. This can lead to improved driver control and confidence.
4. Aesthetics For many enthusiasts, disc brakes look more modern and appealing than traditional drum brakes when peeking through the wheel spokes.
Steps to Convert Drum Brakes to Disc Brakes
1. Research and Gather Parts Before diving into the conversion, research your specific vehicle model to find out what parts are needed. Typical components include - Disc brake rotors - Calipers - Caliper brackets - Brake lines - Master cylinder (in some cases, as you may need one with a higher pressure rating) - Brake pads - Hoses and hardware
Be sure to also check compatibility with your existing components and consider whether you need aftermarket or OEM parts.
2. Prepare the Vehicle Begin the conversion by safely lifting the vehicle using a hydraulic jack and securely supporting it on jack stands. Remove the wheels to gain access to the braking system.
3. Remove Drum Brakes Detach the drum brake assembly. This typically involves removing the drum, then unbolting the backing plate and any other associated components. Take care to note how components are arranged to facilitate reassembly.
4. Install the Disc Brake Components Follow the manufacturer’s instructions to install the disc brake setup. This usually involves mounting the caliper brackets to the spindle and securing them. Ensure that the correct rotor is fitted and aligned properly.
5. Attach Calipers and Pads Install the calipers over the rotors and insert the brake pads into the caliper. Ensure that everything is tightened to the specified torque settings provided by the manufacturer.
6. Upgrade the Brake Lines Depending on your vehicle, you may need to install new brake lines. Ensure that they are routed properly and securely connected. If your system uses a master cylinder that cannot accommodate the additional fluid volume required by disc brakes, consider upgrading to a larger one.
7. Bleed the Brake System Once everything is installed, it’s crucial to bleed the brake system to remove any air bubbles. Start with the caliper furthest from the master cylinder and work your way to the nearest one.
8. Test Drive Before taking your vehicle on long trips, conduct a test drive in a safe area to ensure that the brakes function properly. Pay attention to any unusual noises or behaviors.
Considerations
- Professional Help If you’re not comfortable with mechanical work, consider hiring a professional to handle the conversion. - Legal and Safety Concerns Ensure that your modifications comply with local vehicle regulations and safety standards. Some modifications may require inspections or approvals.
In conclusion, converting from drum to disc brakes can significantly enhance your vehicle's performance and safety. By following the steps outlined above and paying attention to detail, you can accomplish this upgrade effectively. Enjoy your improved braking system and the added confidence it brings!
