Brakes

Quick Summary

Carbon ceramic rotors are precision-engineered components with significant financial value, and they demand careful handling at every stage. From unboxing a new rotor to installing it on your vehicle, from storing a track car over winter to shipping rotors across the country, the way you handle and store these components directly affects their structural integrity and performance. This AME Motorsport guide covers every practical scenario, including unpacking, workshop handling, short-term and long-term storage, seasonal vehicle preparation, and shipping protection. Technology for Everyone means ensuring that every owner has the knowledge to protect their investment from the moment it arrives.

Understanding Carbon Ceramic Material Properties for Handling

Carbon ceramic rotors are made from carbon fibre reinforced silicon carbide (C/SiC), a material that combines extreme hardness with relatively low weight. While this material is extraordinarily resistant to heat, wear, and corrosion during normal brake operation, it has specific vulnerabilities during handling and storage that differ from iron rotors.

Impact sensitivity: Despite their hardness, carbon ceramic rotors are brittle compared to iron. An iron rotor dropped onto a concrete floor will likely survive with a cosmetic mark. A carbon ceramic rotor subjected to the same impact may develop a chip, crack, or internal micro-fracture that compromises its structural integrity. The material excels under the distributed, gradual forces of braking but is less forgiving of sudden, concentrated impact loads.

Surface contamination sensitivity: The rotor braking surface must remain free of oils, greases, cleaning chemicals, and other contaminants that could interfere with the pad transfer layer. Contamination during handling is one of the most common causes of post-installation performance issues, including noise, vibration, and inconsistent braking.

Moisture immunity: Unlike iron rotors, carbon ceramic material does not rust or corrode. This is a significant advantage for storage, as the rotor itself does not require anti-corrosion treatment or climate-controlled storage to prevent surface degradation. Whether you are storing rotors for a Porsche 997 Turbo over winter or keeping a spare set for your Chevrolet Corvette Z06 C7, the same handling principles protect your investment.

Receiving and Unboxing New Rotors

The first handling opportunity is when your new rotors arrive. Careful unboxing sets the foundation for successful installation.

Inspect the Outer Packaging

Before opening, examine the shipping box for signs of transit damage. Look for crushed corners, punctures, wet areas, or damage indicators on the packaging. If the outer box shows significant damage, photograph it from multiple angles before opening and note it for the shipping carrier.

Unboxing Procedure

Initial Inspection

With the rotor on your workbench, perform a thorough visual inspection.

• Braking surface: Check both faces for chips, cracks, scratches, or surface blemishes
• Outer edge: Examine the full circumference for chips or damage
• Ventilation channels: Look through the edge for any blocked or damaged internal vanes
• Rotor hat: Inspect the metallic mounting hub for dents, thread damage, or surface contamination
• Mounting holes: Verify all mounting holes are clean and correctly machined

If any damage is found, photograph it immediately and contact AME Motorsport before proceeding with installation.

Workshop Handling Best Practices

Whether you are installing rotors, performing maintenance, or temporarily removing them for other vehicle work, workshop handling practices prevent accidental damage.

How to Carry a Carbon Ceramic Rotor

• Two-hand carry: Always carry a rotor with both hands, supporting it from underneath. One hand under the disc, the other stabilising from the hat or opposite edge
• Face orientation: Carry the rotor with the braking face vertical (like carrying a dinner plate on edge) whenever possible. This reduces the risk of the braking surface contacting workbench edges or other objects
• Walk, do not rush: Move deliberately. A trip or stumble while carrying a carbon ceramic rotor can turn a routine task into an expensive mistake

Where to Set Down a Rotor

• Always on a padded surface: Never place a carbon ceramic rotor directly on a metal workbench, concrete floor, or any hard surface. Use a foam mat, clean towel, or the original packaging material
• Braking surface protection: If setting the rotor face-down, ensure the surface beneath is clean, soft, and free of grit or debris that could scratch or contaminate the braking face
• Keep away from edges: Position the rotor well back from the edge of any surface. A nudged rotor falling from a workbench height will likely be damaged beyond use

Protecting During Other Vehicle Work

If you need to work on other vehicle components with the carbon ceramic rotors exposed (wheels off), protect the rotor faces from accidental contact with tools, debris, or cleaning chemicals.

• Cover exposed rotors with a clean cloth or purpose-made rotor cover
• Do not lean tools against the rotor face
• Avoid spraying cleaning products near exposed rotors unless they are specifically carbon ceramic safe
• Keep the work area clean to prevent grit and debris from landing on the rotor surface

Short-Term Storage (Days to Weeks)

Short-term storage covers situations like waiting for other installation components to arrive, preparing for a track event, or storing removed rotors during other vehicle work.

Storage Conditions

• Indoor, dry location: A garage, workshop, or climate-controlled space is ideal. Avoid outdoor storage, even in covered areas where temperature swings and humidity are uncontrolled
• Temperature: Ambient indoor temperatures are fine. Carbon ceramic material is thermally stable across a wide range. Avoid extreme cold below minus 20 degrees Celsius or direct heat exposure from heaters, welding equipment, or direct sunlight through windows
• Humidity: While the carbon ceramic material itself is moisture-immune, the metallic rotor hat (typically aluminium or iron) can corrode in humid conditions. Moderate indoor humidity is acceptable

Storage Position

• Vertical storage is preferred: Store rotors standing on their edge on a padded surface, like books on a shelf. This distributes weight evenly and keeps both braking faces accessible for inspection
• If stored flat: Place a clean, soft material between stacked rotors to prevent surface contact. Do not stack more than two rotors to limit weight on the lower disc
• Separate from other components: Do not store rotors in contact with metal parts, tools, or chemicals

Protection During Storage

• Keep in original packaging if available: The custom foam inserts are designed to protect the rotor
• If original packaging is unavailable: Wrap the rotor in clean, lint-free cloth or bubble wrap. Avoid materials that shed fibres (paper towels, newspaper) or leave adhesive residue (tape directly on the braking surface)
• Labelled: Mark each rotor with its position (front left, front right, etc.) if storing a set

Long-Term Storage (Months to Years)

Long-term storage applies to seasonal vehicles, spare rotors kept in inventory, or vehicles being stored for extended periods.

Rotors Removed from the Vehicle

Shipping Carbon Ceramic Rotors

Whether you are sending rotors for refurbishment, selling a used set, or relocating your vehicle parts across the country, shipping carbon ceramic rotors requires specific packaging to prevent transit damage.

Packaging Requirements

Inner protection: Each rotor must be individually wrapped in a minimum of 20 mm thick closed-cell foam or bubble wrap. The wrapping must cover the entire rotor, including the braking surfaces, edges, and hat section.

Separation: If shipping multiple rotors in one box, each rotor must be separated by rigid dividers (cardboard or foam panels at least 10 mm thick) in addition to individual wrapping. Rotors must never contact each other during transit.

Box selection: Use a double-walled corrugated box rated for the weight. Carbon ceramic rotors are lighter than iron equivalents but still significant, typically 4 to 8 kg per rotor depending on application. The box must be at least 50 mm larger than the wrapped rotor on all sides to accommodate cushioning material.

Void filling: Fill all empty space in the box with cushioning material (foam peanuts, crumpled paper, or air pillows) to prevent movement. The rotor should not shift or rattle when the sealed box is shaken.

Sealing and labelling: Seal the box with heavy-duty packing tape. Label clearly with "FRAGILE" and "THIS SIDE UP" markings. Include "CARBON CERAMIC - HANDLE WITH CARE" on at least two sides.

Shipping Carrier Selection

• Choose a carrier with tracking and insurance: The value of carbon ceramic rotors warrants full insurance coverage. Declare the actual value
• Avoid economy ground services for long distances: Extended transit time increases the number of handling events and the probability of damage
• Specify no stacking if possible: Request that the package not be placed under heavy items

Receiving Shipped Rotors

When you receive shipped rotors, inspect them immediately:

Frequently Asked Questions

Can carbon ceramic rotors be stored outdoors?

Carbon ceramic material itself does not rust or corrode, so the rotor disc can tolerate outdoor exposure without surface degradation. However, the metallic rotor hat (typically aluminium or iron) is susceptible to corrosion from moisture and salt exposure. Additionally, outdoor storage exposes rotors to potential impact damage from falling objects, animal activity, and temperature extremes that can affect packaging materials. Indoor storage in a dry, clean environment is strongly recommended. If temporary outdoor storage is unavoidable, wrap the rotor thoroughly, protect it from direct weather exposure, and bring it indoors at the earliest opportunity.

Do I need to apply any protective coating to carbon ceramic rotors during storage?

Do not apply any coating, oil, or protectant to the carbon ceramic braking surfaces. These surfaces must remain clean and uncontaminated to function properly. Coatings on the braking surface will interfere with pad transfer layer formation and must be completely removed before installation. However, applying a light anti-corrosion spray to the metallic hat section and mounting surfaces is recommended for long-term storage. Be precise in application and ensure no overspray reaches the braking faces.

How should I store a vehicle with carbon ceramic brakes over winter?

Clean the braking system thoroughly to remove road salt, brake dust, and debris. If possible, avoid engaging the parking brake for the storage duration, as prolonged pad-to-rotor contact can cause material bonding. Use wheel chocks for parking security instead. Place the vehicle in a dry, indoor space. Consider placing thin spacer shims between pads and rotors to prevent constant contact. Apply anti-corrosion protection to caliper bodies and exposed metal hardware. When the vehicle returns to service, perform a visual inspection of all brake components, flush the brake fluid, and complete a light re-bedding procedure to re-establish pad-to-rotor interaction.

Can I ship carbon ceramic rotors via standard parcel services?

Yes, standard parcel services can be used provided the packaging is adequate. Individual wrapping with at least 20 mm of closed-cell foam, rigid separation between multiple rotors, a double-walled corrugated box with void filling, and clear fragile labelling are the minimum requirements. Select a service that includes tracking and insure the shipment for the full replacement value. Avoid economy services with extended transit times and multiple handling transfers. The goal is to minimise the number of times the package is handled and the duration of transit.

What is the best position for storing carbon ceramic rotors, flat or vertical?

Vertical storage is preferred. Standing rotors on their edge on a padded surface distributes weight evenly and keeps both braking faces accessible for inspection without needing to move the rotor. If storing flat (horizontally), never stack more than two rotors, and always place a clean, soft separator material between them to prevent surface contact. Flat storage of a single rotor is acceptable on a clean, padded surface. The key concern with flat stacking is that weight from upper rotors can cause surface marks or dust compression on the lower rotor's braking face.

How do I handle a carbon ceramic rotor that has been contaminated with oil or grease?

If oil, grease, or another contaminant contacts the braking surface, clean it immediately. Spray the affected area generously with carbon ceramic safe brake cleaner and wipe with a clean, lint-free cloth. Repeat the cleaning process at least three times, using a fresh section of cloth each time. After cleaning, allow the surface to dry completely. Inspect under strong light to confirm no visible residue remains. If the rotor is installed on the vehicle and contamination has occurred, a re-bedding procedure after cleaning re-establishes the pad transfer layer on the cleaned surface. Severe contamination that penetrates the surface texture may require professional assessment.
