Introduction to Ford 8.8 Disc Brake Conversion
Converting Ford 8.8 axles to disc brakes is a popular upgrade among enthusiasts who want to improve the braking performance of their vehicles. Disc brakes offer several advantages over drum brakes, including increased stopping power, reduced fade, and better modulation.
There are several different types of disc brake conversion kits available, so it’s important to do your research before making a purchase.
The most common type of disc brake conversion kit for the Ford 8.8 axle is the bolt-on kit. These kits include everything you need to mount the calipers and rotors to the axle, including new caliper brackets, rotors, and brake pads.
Bolt-on kits are relatively easy to install and can be completed in a few hours with basic tools.
Another type of disc brake conversion kit is the weld-on kit. These kits require you to weld the caliper brackets to the axle, which is a more difficult and time-consuming process than bolt-on kits. However, weld-on kits are generally stronger and more durable than bolt-on kits, and they can be used with larger calipers and rotors.
Which Kit is Right for You?
The best disc brake conversion kit for you will depend on your specific needs and budget. If you’re looking for a quick and easy installation, a bolt-on kit is a good option. If you’re looking for the strongest and most durable kit, a weld-on kit is a better choice.
Ultimately, the decision of which kit to purchase is up to you.

Installation Steps for Different Axle Models, Ford 8.8 disc brake conversion
The installation steps may vary slightly depending on the model of the Ford 8.8 axle. The following table compares the installation steps for three common axle models:
| Axle Model | Installation Steps |
|---|---|
| Open Differential |
|
| Traction-Lok Differential |
|
| Limited Slip Differential |
|
Common Challenges and Solutions
During the installation process, you may encounter some common challenges. The following list provides some solutions to these challenges:
- The disc brake brackets do not fit properly.This can be caused by a number of factors, such as the wrong brackets being used or the axle being bent. Check to make sure that you are using the correct brackets and that the axle is not bent.
For those seeking to upgrade their braking systems, the 68437098ab module anti lock brake system is a reliable choice. It enhances vehicle safety by preventing wheel lockup during braking, ensuring optimal control and stability. Additionally, for those interested in converting to disc brakes, the dana 60 rear disc brake conversion kit provides a comprehensive solution for improved braking performance and reliability.
If the axle is bent, it will need to be replaced.
- The calipers are not aligned properly.This can cause the brakes to drag or not work properly. Make sure that the calipers are aligned properly and that the pads are making contact with the rotors.
- The brake lines are leaking.This can be caused by a number of factors, such as the lines being damaged or the fittings being loose. Check the brake lines for damage and tighten the fittings.
- The brakes are not working properly.This can be caused by a number of factors, such as the pads being worn out or the master cylinder being faulty. Check the pads for wear and replace them if necessary. If the master cylinder is faulty, it will need to be replaced.
Brake System Integration
Integrating the new disc brakes with the existing brake system is crucial to ensure optimal braking performance. Here’s how to connect brake lines, hoses, and calipers:
Connecting Brake Lines and Hoses
Connect the brake lines to the calipers using brake fittings and banjo bolts. Tighten the bolts securely, but avoid overtightening. Use new copper washers to ensure a leak-proof seal.
Connecting Calipers
Mount the calipers onto the axle brackets and secure them with the appropriate bolts and washers. Connect the brake hoses to the calipers and tighten the fittings.
Bleeding the Brake System
Bleeding the brake system is essential to remove any air trapped in the lines. Start by filling the master cylinder with brake fluid. Then, using a brake bleeder tool, open the bleeder valve on each caliper and pump the brake pedal to force out the air.
Continue bleeding until clear brake fluid flows from the bleeder valve.
Final Adjustments and Testing
Once the disc brake conversion is complete, it’s crucial to perform thorough adjustments and testing to ensure optimal brake performance. These steps are essential to verify the proper functioning of the new braking system and identify any potential issues.
Brake Adjustments
Fine-tuning the brake adjustments is necessary to achieve balanced and responsive braking. This involves:
- Brake Pad Adjustment:Ensure the brake pads are evenly spaced and make full contact with the rotors. This is achieved by adjusting the caliper mounting brackets or shims.
- Parking Brake Adjustment:Adjust the parking brake cables to provide adequate holding power without excessive tension.
Testing Checklist
A comprehensive testing checklist is essential to verify the effectiveness of the disc brake conversion:
- Initial Inspection:Visually inspect all components for proper installation and any signs of damage or leaks.
- Brake Pedal Feel:Test the brake pedal feel for firmness and responsiveness. It should provide a smooth and consistent pedal action.
- Stopping Power:Perform controlled stops at various speeds to assess the braking power and pedal modulation.
- Brake Fade:Conduct repeated stops to check for brake fade, which indicates overheating or insufficient brake fluid.
- Parking Brake Functionality:Test the parking brake’s ability to hold the vehicle securely on an incline.
Potential Issues
During the testing phase, certain issues may arise that require attention:
- Brake Noise:Excessive brake noise can indicate misaligned pads, worn components, or improper bedding-in procedures.
- Brake Pull:Uneven braking or pulling to one side may indicate issues with brake caliper alignment or pad wear.
- Brake Pedal Pulsation:Pulsation or vibration in the brake pedal can be caused by warped rotors or uneven pad wear.
