Setup and Installation
Professional installation is recommended for this brake kit. Installation typically requires common hand tools used for routine brake service. Always ensure the vehicle is securely supported on jack stands before beginning work.
Pre-Installation Checks:
- Wheel Clearance: This brake kit may require 18-inch or larger wheels or wheel spacers for proper fitment. Refer to the wheel clearance diagram to verify compatibility with your specific wheels.
- Brake Lines: Ensure you have the necessary brake lines (Part #WIL-220-11771) as they are not included in this kit.
- Brake Fluid: Use high-quality brake fluid, such as Wilwood 570 Brake Fluid.
General Installation Steps (Consult a service manual for detailed vehicle-specific instructions):
- Safely lift and support the vehicle. Remove the wheels.
- Remove the existing brake calipers, rotors, and mounting hardware.
- Clean the wheel hub and mounting surfaces thoroughly.
- Install the new Wilwood mounting brackets onto the vehicle's spindle.
- Mount the Wilwood drilled rotors onto the hub.
- Install the AERO6 calipers onto the mounting brackets, ensuring proper alignment over the rotor.
- Insert the brake pads into the calipers.
- Connect the new brake lines to the calipers and vehicle's brake system.
- Bleed the entire brake system to remove all air.
- Reinstall the wheels and torque lug nuts to manufacturer specifications.
- Perform a thorough test drive in a safe area to ensure proper brake function.

Operating Considerations
Brake System Break-In:
After installation, it is crucial to properly break in the new brake pads and rotors. This process ensures optimal performance and longevity. Follow these steps:
- Perform 10-12 moderate stops from approximately 30 mph (48 km/h) down to 5 mph (8 km/h). Allow a few seconds between stops for the brakes to cool slightly.
- Avoid hard braking or bringing the vehicle to a complete stop during this initial phase.
- After the moderate stops, allow the brakes to cool completely for at least 15-20 minutes.
- Perform 3-5 harder stops from approximately 60 mph (97 km/h) down to 10 mph (16 km/h). Again, avoid coming to a complete stop.
- Allow the brakes to cool completely before normal driving.
Proper break-in helps to transfer a thin layer of pad material onto the rotor surface, which is essential for consistent braking performance and reduced noise.
Maintenance
Regular maintenance is vital for the safety and performance of your Wilwood brake system.
- Regular Inspection: Periodically inspect brake pads for wear, rotors for cracks or excessive wear, and brake lines for leaks or damage.
- Brake Fluid: Check brake fluid level and condition regularly. Replace brake fluid according to your vehicle manufacturer's recommendations or more frequently for performance driving. Use only DOT 3 or DOT 4 brake fluid as specified.
- Cleaning: Keep calipers and rotors clean from dirt and debris.
- Pad Replacement: Replace brake pads when they reach their minimum thickness specification. Always replace pads in axle sets.
Troubleshooting
| Symptom | Possible Cause | Solution |
|---|---|---|
| Reduced Braking Performance | Air in brake lines, worn pads, improper break-in, contaminated fluid. | Bleed brake system, inspect/replace pads, re-perform break-in, flush/replace fluid. |
| Brake Noise (Squealing/Grinding) | Worn pads, improper pad seating, debris, rotor surface issues. | Inspect/replace pads, clean components, check for debris, ensure proper break-in. |
| Vibration During Braking | Warped rotors, uneven pad wear, loose components. | Inspect rotors for runout, check pad wear, verify all mounting hardware is tight. |
| Brake Pedal Feels Spongy | Air in brake lines, low brake fluid, master cylinder issue. | Bleed brake system thoroughly, check fluid level, inspect master cylinder. |
If you encounter persistent issues, consult a qualified automotive technician.
