Absolutely! Upgrading to disc brakes on a 1985 Ford TTB Dana 44 is a popular choice. Here’s a breakdown of what you need to know:

Why Upgrade to Disc Brakes?

  • Improved Stopping Power: Disc brakes generally provide better stopping power than drums.
  • Heat Dissipation: They dissipate heat more effectively, reducing brake fade.
  • Easier Maintenance: Changing pads is usually simpler than dealing with drum systems.

Disc Brake Conversion Kit

Several companies offer conversion kits. Look for kits designed specifically for the TTB Dana 44 to ensure proper fitment. Common parts included are:

  • Rotors and Calipers: Ensure they’re compatible with the TTB Dana 44.
  • Brake Pads: Usually included in kits.
  • Brackets and Hardware: Essential for mounting the calipers and rotors.
  • Hoses and Lines: Ensure these are rated for your truck’s weight and intended use.

Installation Considerations

  1. Compatibility: Confirm that the kit matches your axle configuration.
  2. Tools Needed: Basic hand tools, a torque wrench, and possibly a brake bleeder.
  3. Time: Set aside a weekend for the swap, especially if it’s your first time.

Pro Tips

  • Master Cylinder: Sometimes, it’s necessary to upgrade the master cylinder for optimal performance with disc brakes. Check compatibility.
  • Brake Bias: Consider an adjustable proportioning valve to fine-tune front-to-rear brake bias.
  • Wheel Compatibility: Make sure your wheels have the necessary clearance for the new brake setup.

Before You Start

  • Research: Double-check with product reviews and forums like the Bullnose Ford subreddit for real-world feedback.
  • Safety First: Always use jack stands and ensure the vehicle is securely supported before starting work.
