Our material is a next-generation Carbon Fibre Reinforced Ceramic (CFRC) which is produced by Surface Transforms' proprietary processes, transforming Carbon-Carbon into our Carbon-Silicon Carbide (CSiC) ceramic.

Whilst the carbon-ceramic discs you find on production road cars conventionally use discontinuous (chopped) carbon fibre, ST interweaves continuous carbon fibre to form a 3D multi-directional matrix, producing a stronger and more durable product with 3x the heat conductivity of standard production components, this keeps the brake system temperature down and the brake performance consistent.

Surface Transforms has developed unique patented next-generation Carbon-Ceramic Technology that provides the ultimate braking performance for road and track.

Here's seven reasons why you need this technology on your vehicle:

• Weight savings of up to 70% compared to iron brakes (typically 20kg of unsprung weight)
• Improved handling and driveability
• Improved NVH (less noise, vibration and harshness)
• Improved performance (in both wet and dry conditions)
• Reduced brake wear – giving increased life
• Corrosion Free
• Outstanding performance, even from cold

Diagram Ref No 1, 6, 7

What The Components Do:

• Brake Pads: The pads are the friction-material blocks that the brake calipers press against the discs (rotors) when you apply the brakes. Good quality pads ensure strong, predictable braking force, proper heat handling, minimal fade, low noise, and safe stopping distances. Over time, they wear down and must be replaced to maintain performance.
• Brake Discs / Rotors: The front discs provide the surface against which the brake pads clamp. They convert the kinetic energy of the moving car into heat via friction. The rotors must maintain flatness, correct thickness, no warping or cracking, and correct dimensions (e.g., diameter, thickness, venting/helical design) for optimum braking performance.
• Pad Wear Sensor / Accessory: This wear sensor monitors pad thickness and signals the driver when the pad material is low, providing a safety warning. Using the correct sensor ensures the braking wear system works properly.

Why Replacement Matters & Signs That It’s Time:

• Brake Pads: Signs that the pads need replacement: reduced braking performance, longer stopping distances, brake squeal or screech (wear indicators contacting the rotor), visible wear of pad material (thickness nearly gone), vibration or pulsing under braking (could indicate rotor or pad issue). If you’re replacing discs anyway, doing pads at the same time is a smart practice.
  
• Brake Discs: You should inspect for warping (causes vibration or judder through the pedal), surface cracking (especially under heavy use), thickness below the minimum spec, excessive lateral run-out, corrosion or groove wear. If any of these symptoms show, replacement is recommended. Replacing discs and pads together ensures optimal performance.
  
  

Why This Package Matters:

• OEM quality & compatibility: Using genuine Porsche brakes for the correct brake system ensures the correct material, correct size, correct design for that vehicle’s braking system.
  
• Correct for “Comfort Equipment” option: On 992-series 911s, the braking system option (“comfort equipment” vs ceramic) determines rotor size and pad compound. This package is specified for the steel rotor-based comfort equipment variant, so using it on a ceramic version would be incorrect.
  
• Cost-effectiveness & convenience: Buying a matched pad + disc package ensures the parts are designed to work together. Since you will likely need to remove wheels, calipers, etc. anyway, doing both discs and pads simultaneously saves labour later.
  
• Maintains vehicle value & performance: For Porsche owners, maintaining the braking system with correct OEM parts ensures the vehicle drives as intended, performs safely at higher speeds, and preserves resale/collector value.

Diagram Ref No 1, 6, 7

What The Components Do:

• Brake Pads: Provide the friction material that the calipers clamp onto the rotors when braking. They wear down over time and determine the initial braking force and pedal feel.
• Brake Discs / Rotors: These are the surfaces the pads contact; they absorb and dissipate the kinetic energy from braking. Proper rotor thickness, flatness and condition are critical for safe, consistent braking.
  
• Wear Sensor: Detects the remaining pad thickness and alerts the driver (via dashboard indicator) when the pads reach their wear limit. Ensures that the brake pads are replaced before excessive wear causes rotor damage or reduced braking capacity.
  
  

Signs Of Needing Replacement:

• Brake pedal feels “soft” or you notice longer stopping distances or less “bite”.
• Squealing or grinding noises coming from front brakes (indicative of worn pads or damaged rotors).
• Vibrations or pulsing through the brake pedal or steering wheel under braking (often rotor warp or surface irregularity).
• Pad wear warning light illuminated (for cars fitted with wear sensors).
• Visual inspection shows pad thickness low, rotor surface badly scored or groove depth exceeded, or rotor minimum thickness below specification.

Why Replacement Matters:

• Brake Balance & Stability: The front brakes on a 911 handle a large portion of the braking load; mismatched or worn components can upset handling or stability under braking.
  
• Component Protection: If pads wear too thin (without sensor warning), the metal backing plate may contact the rotor, causing rotor damage, grooves, vibration or cracking. Fresh pads + rotors + sensor mean you’re protecting all components.
  
• Maintenance Efficiency: Replacing pads and rotors together ensures both surfaces are “fresh” and bedded together. It prevents the “new pad on old rotor” scenario which can cause uneven wear or noise.
  
• Sensor Functionality: The wear sensor ensures you are alerted when pads reach their limit. If the sensor is old or missing, you lose a safety layer.

Diagram Ref No 1, 6, 7

What The Components Do:

• Brake Pads (Rear): These provide the friction material pressed by the calipers onto the rotor to slow the vehicle. Good rear pads ensure stable and balanced braking, prevent drag, maintain adequate stopping power and avoid overheating.
  
• Brake Discs / Rotors (Rear): These are the rotating surfaces that the pads clamp onto. They convert kinetic energy into heat. Rear rotors must maintain correct thickness, flatness, no warping, and surface integrity for optimal performance and brake balance.
  
• Wear Sensor: The sensor monitors pad thickness and triggers a warning when pads are worn out. Using the correct sensor ensures you receive proper maintenance alerts and helps avoid damage to rotors from pads worn down too far.
  
  

Signs Of Needing Replacement:

• Reduced braking performance (especially at the rear): longer stopping distances, brake fade, or a “soft” pedal can indicate pads or rotors worn.
  
• Brake vibration, judder or pulsing from the rear wheels upon braking — can indicate warped rotors or uneven pad/rotor surface contact.
  
• Brake noise: squealing, screeching, or grinding may mean pads are worn, or that rotor damage is present.
  
• Pad wear beyond safe limit: If the wear sensor triggers or manual inspection shows thin pads, you should replace — continuing to drive is risky.
  
• Rotor thickness below minimum or visible damage (grooves, cracks, discoloration) — the rotors need replacing in that case.
  
  

Why Replacement Matter

• Safety and braking performance: The brake system is one of the most safety-critical components of your car. Over time, brake pads wear thin and rotors lose their optimal surface thickness. When this happens, stopping distances increase, and braking response becomes less predictable. Replacing them restores the precise, powerful braking performance Porsche engineers intended.
  
• Proper brake balance: In a Porsche 911 (992), the rear brakes play a major role in stability and weight transfer during deceleration. If rear pads or discs are worn unevenly, it disrupts front-to-rear brake balance, which can affect traction and handling, especially during spirited driving or wet-road braking.
  
• Preventing damage to other components: Worn pads can expose the metal backing plate, which grinds directly into the rotor surface, scoring or cracking the disc. Likewise, a warped or corroded disc can cause accelerated pad wear. Replacing both pads and rotors together prevents these chain-reaction failures and avoids the cost of premature part replacements later.
