2. Setup and Installation

Installation of the Bendix Premium PRT6397 Brake Rotor is designed to be straightforward for qualified technicians or individuals with appropriate automotive experience. It is an OE replacement part, ensuring compatibility with specified vehicle models.

Installation Steps (General Guidance):

1. Safely lift and support the vehicle, then remove the wheel.
2. Remove the caliper and brake pads.
3. Remove the two bolts for the caliper bracket.
4. Locate and remove the small hex-keyed bolt on the disc itself, which secures the rotor to the hub.
5. Carefully remove the old rotor. Note that rust and corrosion may make removal difficult; gentle tapping with a hammer or slight heating may be necessary.
6. Install the new Bendix PRT6397 rotor, ensuring it sits flush against the hub. Secure it with the hex-keyed bolt.
7. Reinstall the caliper bracket and caliper.
8. It is highly recommended to replace brake pads at the same time as rotors for optimal performance and wear. If reusing existing pads, allow for a gentle wear-in period to prevent overheating if pads were grooved or uneven.
9. Reinstall the wheel and lower the vehicle.

3. Operating Instructions

Once installed, the Bendix Premium PRT6397 Brake Rotor provides reliable and consistent braking performance. Its design ensures a quiet and smooth operation, contributing to a comfortable driving experience.

Brake-In Procedure:

After installation, a proper brake-in procedure is crucial for optimal performance and longevity of both the rotors and pads. This typically involves a series of moderate stops from varying speeds, allowing the brake components to gradually heat up and cool down, ensuring proper mating surfaces are established.

Performance Characteristics:

• Smooth and Consistent Braking: Engineered for a responsive and predictable pedal feel.
• Reduced Noise and Vibration: Dynamically balanced to minimize unwanted sounds and vibrations during braking.
• Fade Resistance: Advanced heat dissipation properties help maintain braking effectiveness even under demanding conditions.

4. Maintenance

Regular inspection and maintenance are essential to ensure the continued safe and effective operation of your Bendix brake rotors. While designed for durability, proper care will extend their lifespan and maintain peak performance.

Recommended Maintenance:

• Periodic Inspection: Regularly inspect rotors for signs of wear, such as scoring, grooving, cracks, or excessive rust.
• Thickness Check: Consult your vehicle's manufacturer specifications for minimum rotor thickness. Replace rotors if they fall below this limit.
• Cleanliness: Keep brake components free from dirt, debris, and excessive brake dust.
• Brake Pad Condition: Always ensure brake pads are in good condition and replaced when worn, as worn pads can damage rotors.

5. Troubleshooting

While Bendix brake rotors are manufactured to high standards, issues can occasionally arise. Below are common symptoms and potential causes:

• Vibration or Pulsation during Braking: This can indicate rotor run-out, uneven wear, or warping. Ensure proper installation and check for any damage.
• Excessive Noise (Squealing, Grinding): Often related to worn brake pads, improper brake-in, or foreign material between the pad and rotor. Inspect pads and perform brake-in if necessary.
• Reduced Braking Performance: Could be due to brake fade from overheating, worn pads, or issues with the vehicle's hydraulic system.

If you experience persistent issues, it is recommended to consult a certified automotive technician for diagnosis and repair.
