Overview of the Conversion Process
The conversion process involves several key steps, including:
- Assessing your vehicle’s compatibility and identifying the necessary components
- Removing the existing drum brake assembly and preparing the wheel hub
- Installing the disc brake rotor, caliper, and brake pads
- Upgrading the brake master cylinder and hydraulic system
- Bleeding the brake system and testing the new disc brakes
In the following sections, we will delve deeper into each of these steps, providing detailed instructions and expert tips to ensure a successful conversion. Whether you’re a seasoned mechanic or a DIY enthusiast, this guide will walk you through the process of converting your vehicle’s brake drum to disc brakes with confidence.
How to Convert Brake Drum to Disc Brakes: A Comprehensive Guide
Upgrading your vehicle’s brake system from drum brakes to disc brakes can significantly improve its stopping power and overall safety. While it may seem like a daunting task, converting brake drum to disc brakes is a feasible DIY project with the right guidance. In this article, we’ll walk you through the step-by-step process of converting brake drum to disc brakes, covering the necessary tools, materials, and techniques required for a successful conversion.
Why Convert to Disc Brakes?
Disc brakes offer several advantages over drum brakes, including:
- Improved Stopping Power: Disc brakes provide better heat dissipation, which reduces brake fade and improves overall stopping power.
- Better Resistance to Brake Fade: Disc brakes are less prone to brake fade, which occurs when the brakes overheat and lose their effectiveness.
- Enhanced Safety: Disc brakes provide a more consistent and reliable braking performance, reducing the risk of accidents.
- Increased Durability: Disc brakes have fewer moving parts than drum brakes, making them less prone to wear and tear.
Tools and Materials Needed
Before starting the conversion process, make sure you have the following tools and materials: (See Also: What Does Brake Hold Mean On Honda Accord)
- Disc brake conversion kit (specific to your vehicle make and model)
- Brake fluid
- Brake cleaner
- Wire brush
- Socket set
- Torque wrench
- Caliper piston compressor
- Brake pad wear gauge
- New brake pads and rotors (if not included in the conversion kit)
Step 1: Prepare the Vehicle
Before starting the conversion process, make sure your vehicle is:
- Parked on a level surface
- In park (automatic) or neutral (manual) gear
- Engaged in the parking brake
- Supported by jack stands (if you plan to raise the vehicle)
Step 2: Remove the Drum Brakes
Follow these steps to remove the drum brakes:
- Loosen the lug nuts on the wheel using a lug wrench, but do not remove them yet.
- Remove the wheel using a tire iron, and set it aside.
- Use a socket wrench to remove the drum brake assembly, taking care not to damage the brake lines or ABS sensors.
- Disconnect the brake line from the drum brake assembly, and plug the brake line to prevent brake fluid from leaking out.
- Remove the drum brake hardware, including the brake shoes, springs, and retaining clips.
Step 3: Install the Disc Brake Rotors
Follow these steps to install the disc brake rotors:
- Inspect the disc brake rotors for any signs of damage or wear, and replace them if necessary.
- Apply a thin layer of brake lubricant to the rotor mounting surface.
- Install the disc brake rotor onto the wheel hub, making sure it is properly seated and centered.
- Tighten the rotor mounting bolts in a star pattern to ensure even pressure.
Step 4: Install the Disc Brake Calipers
Follow these steps to install the disc brake calipers:
- Inspect the disc brake calipers for any signs of damage or wear, and replace them if necessary.
- Apply a thin layer of brake lubricant to the caliper mounting surface.
- Install the disc brake caliper onto the rotor, making sure it is properly aligned and seated.
- Tighten the caliper mounting bolts in a star pattern to ensure even pressure.
- Connect the brake line to the caliper, making sure it is properly secured and not leaking.
Step 5: Install the Brake Pads
Follow these steps to install the brake pads:
- Inspect the brake pads for any signs of damage or wear, and replace them if necessary.
- Apply a thin layer of brake lubricant to the brake pad mounting surface.
- Install the brake pads onto the caliper, making sure they are properly seated and aligned.
- Tighten the brake pad retaining clips to ensure they are securely held in place.
Step 6: Bleed the Brake System
Follow these steps to bleed the brake system: (See Also: What Is The Maximum Allowable Brake Drum Diameter)
- Use a brake bleeding kit to remove any air from the brake system.
- Pump the brake pedal several times to remove any air from the brake lines.
- Check the brake fluid level and top it off as necessary.
- Test the brakes to ensure they are functioning properly.
Step 7: Test the Brakes
Follow these steps to test the brakes:
- Drive the vehicle slowly and apply the brakes gently to ensure they are functioning properly.
- Gradually increase the speed and braking pressure to test the brakes under different conditions.
- Check for any signs of brake fade, noise, or vibration.
- Adjust the brake pads and rotors as necessary to ensure proper alignment and clearance.
