1. Introduction
The Hawk Performance Sector 27 Rotor/Pad Kit (Model HK4077.467F) is engineered to provide superior braking performance for your vehicle. This kit features drilled and slotted rotors designed for enhanced cooling and consistent pad contact, along with high-performance brake pads. The beveled, drilled holes facilitate superior cooling under extreme conditions, while the rounded slots ensure consistent contact between the rotor and pad, effectively sweeping away gas and dust. This design results in harder, more precise braking and can lower brake temperatures significantly.
Key benefits of this kit include:
- Greatly improved braking performance
- Lowered brake temperatures
- Precise and predictable control
- Consistent pedal feel
- Long life
2. Setup and Installation
The Hawk Performance Sector 27 Rotor/Pad Kit is designed for direct replacement on compatible vehicles. Due to the critical nature of brake system components, professional installation by a qualified mechanic is strongly recommended. Improper installation can lead to brake failure, serious injury, or death.

2.1 Kit Components
Each Sector 27 Rotor and Pad kit typically includes:
- Two (2) Sector 27 Drilled and Slotted Rotors
- One (1) set of Hawk HPS 5.0 or LTS (Light Truck SUV) Brake Pads (for one axle)
2.2 Pre-Installation Checks
Before installation, ensure all components are free from damage and match the specifications for your vehicle. Verify that the vehicle service type (SUV, Truck) aligns with the product's intended use. It is crucial to follow all vehicle manufacturer's guidelines for brake system service and repair.
3. Operating Performance
Once properly installed, the Hawk Performance Sector 27 Rotor/Pad Kit will significantly enhance your vehicle's braking capabilities. The combination of drilled and slotted rotors with high-performance pads provides a more aggressive bite and improved thermal management compared to standard braking systems.
3.1 Break-in Procedure (Bedding)
For optimal performance and longevity, a proper break-in (bedding) procedure is essential for new brake pads and rotors. Consult the specific break-in instructions provided by Hawk Performance or your installing mechanic. Generally, this involves a series of moderate to firm stops from varying speeds, allowing the brakes to cool between cycles, to properly transfer a layer of pad material onto the rotor surface.
3.2 Driving Characteristics
Expect a more responsive and consistent pedal feel. The design helps to reduce brake fade during heavy use by dissipating heat and clearing away friction material dust and gases. This leads to more predictable and controlled braking, especially under demanding conditions.
4. Maintenance
Regular maintenance is crucial for the safety and performance of your vehicle's braking system. While Hawk Performance components are designed for long life, periodic inspection is necessary.
4.1 Routine Inspections
- Pad Wear: Regularly check the thickness of your brake pads. Replace them when they reach their minimum recommended thickness, typically indicated by wear indicators or visual inspection.
- Rotor Condition: Inspect rotors for excessive wear, deep grooves, cracks, or warping. While Sector 27 rotors are designed for durability, extreme conditions can still cause wear.
- Brake Fluid: Check brake fluid level and condition according to your vehicle manufacturer's recommendations.
- Brake Lines and Calipers: Look for any signs of leaks, damage, or corrosion on brake lines, hoses, and calipers.

4.2 Cleaning
Keep brake components clean from excessive dust and debris. Use appropriate brake cleaner if necessary, ensuring it does not damage other vehicle components.
4.3 Replacement Intervals
Replacement intervals for brake pads and rotors vary significantly based on driving style, vehicle type, and operating conditions. Consult a professional mechanic for advice on when to replace your brake components.
5. Troubleshooting
This section addresses common issues that may arise with brake systems. For any persistent or severe problems, always consult a qualified automotive technician.
| Symptom | Possible Cause | Action |
|---|---|---|
| Squealing/Grinding Noise | Worn brake pads, foreign object, improper installation, or normal high-performance brake noise. | Inspect pads for wear. Check for debris. Ensure proper bedding procedure was followed. If persistent, consult a mechanic. |
| Vibration/Pulsation during Braking | Warped rotors, uneven pad wear, loose wheel bearings, or suspension issues. | Have rotors and pads inspected for runout and wear. Check other suspension components. Professional diagnosis recommended. |
| Reduced Braking Performance (Brake Fade) | Overheated brakes, worn pads/rotors, air in brake lines, or low brake fluid. | Allow brakes to cool. Inspect components for wear. Check brake fluid level and bleed system if necessary. Seek professional help. |
| Pulling to One Side when Braking | Sticking caliper, uneven pad wear, contaminated brake fluid, or suspension alignment issues. | Inspect calipers and brake lines. Check for uneven pad wear. Professional alignment may be needed. |
Important Safety Note: Brake system issues can compromise vehicle safety. Do not attempt repairs if you are not qualified. Always seek professional assistance for brake system diagnosis and repair.
