Upgrading your vehicle’s braking system with a rear disc brake conversion kit can significantly enhance your stopping power and overall safety. Disc brakes offer superior performance compared to traditional drum brakes, providing better heat dissipation, increased stopping distance, and improved modulation.
Overview of Rear Disc Brake Conversion Kits
A rear disc brake conversion kit is a comprehensive package designed to replace your vehicle’s existing drum brakes with disc brakes at the rear axle. These kits typically include all the necessary components, such as calipers, rotors, brake pads, mounting brackets, and brake lines.
Benefits of Installing Rear Disc Brakes
There are several advantages to converting your rear brakes to discs:
- Improved Stopping Power: Disc brakes provide greater stopping force, especially in high-speed or emergency situations.
- Enhanced Heat Dissipation: Disc brakes dissipate heat more efficiently, reducing brake fade and maintaining consistent braking performance.
- Increased Durability: Disc brakes generally have a longer lifespan compared to drum brakes, requiring less frequent maintenance.
- Improved Modulation: Disc brakes offer smoother and more precise braking control.
## How To Install a Rear Disc Brake Conversion Kit
Upgrading your vehicle’s braking system with a rear disc brake conversion kit can significantly improve stopping power, handling, and overall safety. While this project may seem daunting, it’s achievable with the right tools, patience, and a clear understanding of the process. This guide will walk you through the steps involved in installing a rear disc brake conversion kit, empowering you to take control of your vehicle’s performance.
Understanding the Benefits of Disc Brakes
Before diving into the installation process, it’s essential to understand why upgrading to rear disc brakes is beneficial.
* **Improved Stopping Power:** Disc brakes offer superior stopping power compared to drum brakes, especially in high-performance driving situations. This is because the brake pads create a larger contact area with the rotor, resulting in more friction and efficient energy dissipation.
* **Enhanced Handling:** Rear disc brakes contribute to improved vehicle handling and stability, particularly during cornering and braking maneuvers. The increased braking force at the rear wheels helps to maintain traction and prevent wheel lock-up, leading to a more controlled driving experience.
* **Reduced Brake Fade:** Disc brakes are less prone to brake fade, a phenomenon where brake performance deteriorates under prolonged or heavy braking. This is because the brake pads dissipate heat more effectively, maintaining consistent braking power even in demanding conditions.
* **Increased Durability:** Disc brake components are generally more robust and durable than drum brake components. They are less susceptible to wear and tear, resulting in longer service life and reduced maintenance requirements.
Choosing the Right Conversion Kit
Selecting the appropriate rear disc brake conversion kit is crucial for a successful installation. Consider the following factors:
* **Vehicle Compatibility:** Ensure the conversion kit is specifically designed for your vehicle make, model, and year.
* **Brake System Size:** Choose a kit that matches the desired brake system size for your vehicle. Larger rotors and calipers provide greater stopping power but may require modifications to your wheels or suspension.
* **Quality and Brand Reputation:** Opt for a reputable brand known for producing high-quality brake components. (See Also: How To Paint Brake Calipers)
* **Installation Instructions and Support:** Look for a kit that comes with detailed installation instructions and access to technical support if needed.
Gathering the Necessary Tools and Materials
Before commencing the installation, gather all the required tools and materials:
* **Tools:** Socket wrench set, torque wrench, jack, jack stands, wrenches, pliers, brake bleeder kit, brake fluid, safety glasses, gloves, and shop rags.
* **Materials:** Rear disc brake conversion kit, brake pads, brake fluid, new brake lines (if required), and wheel bearings (if required).
Step-by-Step Installation Process
1. **Prepare the Vehicle:** Park your vehicle on a level surface, engage the parking brake, and chock the front wheels.
2. **Disconnect the Battery:** Disconnect the negative terminal of the battery to prevent any electrical shorts.
3. **Remove the Rear Wheels:** Use a lug wrench to loosen the lug nuts and remove the rear wheels.
4. **Remove the Drum Brakes:**
* Remove the brake drum retaining clips and carefully remove the brake drums.
* Disconnect the brake lines from the wheel cylinders.
5. **Remove the Wheel Cylinders:**
* Remove the bolts securing the wheel cylinders to the backing plate.
* Carefully remove the wheel cylinders.
6. **Install the New Brake Components:** (See Also: How Hot Can Brake Calipers Get)
* Install the new brake caliper brackets onto the backing plate, ensuring they are properly aligned.
* Install the new brake calipers onto the caliper brackets, securing them with the provided bolts.
* Install the new rotors onto the wheel hubs.
7. **Connect the Brake Lines:**
* Connect the new brake lines to the calipers, ensuring a secure and leak-free connection.
* Bleed the brake lines to remove any air bubbles.
8. **Install the Brake Pads:**
* Install the new brake pads into the calipers, ensuring they are properly seated.
9. **Reinstall the Wheels:**
* Mount the rear wheels onto the vehicle.
* Tighten the lug nuts securely.
10. **Reconnect the Battery:** Reconnect the negative terminal of the battery.
11. **Test the Brakes:**
* Pump the brake pedal several times to ensure proper brake fluid pressure.
* Test the brakes in a safe and controlled environment, gradually increasing braking force.
* Check for any leaks or unusual noises.
Important Safety Considerations
When working on your vehicle’s braking system, safety should be your top priority.
* **Always use jack stands:** Never rely solely on a jack to support your vehicle.
* **Wear safety glasses and gloves:** Protect your eyes and hands from debris and brake fluid. (See Also: What Is Brake Bias In F1)
* **Bleed the brakes properly:** Air in the brake lines can significantly reduce braking performance.
* **Test the brakes thoroughly:** After installation, ensure the brakes are functioning correctly before driving on public roads.
