Install Guide: Front Brake Cooling Kit (Classic Mustang)

Overview

This guide walks through installation of the front brake cooling backing plates and ducting.

The process is straightforward and requires basic hand tools. Plan for about 1–2 hours for a complete install.

Tools & Supplies

• Jack and jack stands

• Lug wrench

• Socket set / wrenches

• Pliers (for cotter pin)

• Flathead screwdriver or punch (dust cap removal)

• High-temp grease (for bearings if needed)

Step 1: Remove Wheel and Caliper

1. Safely raise the vehicle and remove the front wheel.

2. Remove the two caliper mounting bolts.

3. Carefully set the caliper aside.

Do not let the caliper hang by the brake hose.

Step 2: Remove Hub and Rotor Assembly

1. Remove the dust cap from the hub.

2. Pull the cotter pin from the spindle nut.

3. Remove:

   • Nut retainer

   • Spindle nut

4. Slide the rotor/hub assembly off the spindle.

5. Remove bearings as needed and set aside.

Step 3: Remove Backing Plate and Caliper Bracket

1. Locate the four bolts securing:

   • Caliper bracket

   • Factory backing plate

2. Remove the four nuts and bolts.

3. Remove both the caliper bracket and factory backing plate.

Step 4: Install Brake Cooling Backing Plate

1. Clean the spindle mounting surface.

2. Position the brake cooling backing plate between:

   • Spindle

   • Caliper bracket

3. Reinstall the caliper bracket over the new backing plate.

4. Install the four bolts and nuts.

Torque Spec

For 3/8”-24 fasteners:

Torque to approximately 30–35 ft-lbs

(Verify based on your hardware and application.)

Step 5: Reinstall Hub and Rotor

1. Reinstall bearings (grease if needed).

2. Slide the rotor/hub assembly back onto the spindle.

3. Install:

   • Spindle nut

   • Nut retainer

4. Set proper bearing preload:

   • Tighten while rotating rotor

   • Back off slightly

   • Ensure smooth rotation with minimal play

5. Reinstall:

   • Cotter pin

   • Dust cap

Step 6: Reinstall Caliper

1. Reinstall the caliper over the rotor.

2. Install and tighten caliper mounting bolts.

Step 7: Attach Brake Ducting

1. Attach 2.5” high-temperature silicone duct hose to the backing plate inlet.

2. Secure using a hose clamp.

Step 8: Route Ducting

1. Route the duct hose:

   • Behind the spindle assembly

   • Along the frame rail

   • Toward the front of the vehicle

2. Connect to your inlet scoop (not included).

Step 9: Check Clearance (IMPORTANT)

Before reinstalling wheels:

• Turn steering fully left and right

• Check for:

  • Hose interference

  • Contact with suspension components

  • Kinks in ducting

Step 10: Final Assembly

1. Reinstall wheels

2. Lower vehicle

3. Perform a final visual inspection

Final Notes

• Ensure ducting is clear of moving suspension components

• Avoid sharp bends or crushed sections in hose

• Re-check all fasteners after initial use

Why This Matters

Brake cooling works by directing airflow into the center of the rotor, helping reduce temperatures and maintain consistent braking performance.

On classic Mustangs with smaller rotors, this can make a noticeable difference during repeated braking or track use.
