For cars WITHOUT Ceramic Brake PCCB

Engineered to work perfectly with OE and Zimmermann brake discs, these front brake pads deliver progressive braking response, excellent resistance to brake fade, low brake noise and reduced brake dust while maintaining the braking characteristics Porsche intended.

What Do the Front Brake Pads Do?

Front brake pads are the primary friction components of your Porsche's braking system. When the brake pedal is pressed, hydraulic pressure forces the pads against the front brake discs, generating friction that converts the vehicle's kinetic energy into heat, slowing and safely stopping the vehicle.

Their primary functions include:

  • Providing the majority of the vehicle's braking force.
  • Delivering smooth, progressive stopping performance.
  • Maintaining braking stability under heavy deceleration.
  • Supporting Porsche ABS and Porsche Stability Management (PSM).
  • Providing precise pedal feel and driver confidence.
  • Delivering reliable braking performance in all driving conditions.

Because the front axle performs most of the braking work, maintaining high-quality brake pads is essential for optimum safety and performance.

Why Do Front Brake Pads Wear Out?

Brake pads are designed as consumable service components and naturally wear through normal operation. Common causes include:

  • Continuous friction against the brake discs.
  • High temperatures generated during braking.
  • Fast road and spirited driving.
  • Track day use. Repeated heavy braking.
  • Natural wear of the friction material.
  • High vehicle mileage.
  • Brake disc wear affecting pad contact.

Performance models such as the 991 Turbo, 992 and 718 GTS 4.0 place greater demands on the braking system, increasing brake pad wear during enthusiastic driving.

When Should the Front Brake Pads Be Replaced?

Replacement is recommended whenever:

  • The brake pad wear warning light is illuminated.
  • The friction material reaches Porsche's minimum service thickness.
  • Braking performance begins to decline.
  • Squealing or grinding noises develop.
  • Uneven brake pad wear is detected.
  • Front brake discs are being replaced.
  • During scheduled brake servicing.
  • Before track events if the remaining pad material is approaching its wear limit.

For optimum braking performance, brake pad wear sensors should always be replaced whenever new brake pads are installed to ensure accurate brake wear monitoring and reliable operation.

Quality
Our product range in the brake pads sector includes over 1,000 different items, covering the vast majority of vehicles currently on the road. To ensure wholesalers have rapid access to our products, we maintain a warehouse with the capacity to store more than 120,000 sets of brake pads.

Every vehicle has its own unique characteristics and therefore specific requirements for brake pads. Our products are made using up to 25 different raw materials, carefully combined to achieve the highest standards of quality, reliability, and safety. Each brake pad undergoes a rigorous 2–3 year development process, including extensive road testing. The “OE Approvals” from leading automobile manufacturers are a testament to the expertise and precision of our specialists.

Your Advantages:

  • Over 1,000 product variants
  • Large storage capacity (120,000 sets) for rapid availability
  • OE quality standards
  • OES quality Long service life
  • Smooth and consistent braking performance
  • Complies with ECE R90 regulations
  • Excellent corrosion protection
  • Complete range from a single supplier 

What they do
  • These pad units convert the motion of your vehicle into stopping power by pressing the friction material against the disc, transforming kinetic energy into heat in a controlled manner—ensuring reliable deceleration, consistent response and minimal fade.
  • The pb:z line uses friction-material mixtures drawn from up to 25 different raw materials, tailored specifically for each vehicle’s braking system and usage profile.
  • Manufactured with careful control of temperature, pressure and time, the production process ensures that each pad set meets the design criteria for braking comfort, precision and functional safety.
  • Your advantage: the pb:z range in ‘OES-quality’ (Original Equipment-Standard quality) delivers highest level of brake comfort, precision for highest functional safety, and is available for some special applications.
  • Further benefits: long lifespan, very smooth performance, and conformity to ECE R90 standards for braking performance.

Why brake pads fail
  • Friction-material wear: Over time, the pad material thins, reducing the effective contact area and friction coefficient. When the pad becomes too thin, stopping distance increases and performance deteriorates.
  • Thermal overload or glazing: Under repeated heavy braking or mismatched pad/disc pairing, the surface can harden or glaze, losing its ideal friction characteristics—leading to fade or uneven braking.
  • Uneven pad-to-disc contact: If pads don’t make full uniform contact due to disc warpage, caliper misalignment, or incorrect installation, only portions of the pad carry load, which accelerates wear or creates hotspots.
  • Corrosion or contaminants: Although the pb:z line offers optimal corrosion protection, external factors (salt, water ingress, lack of maintenance) can degrade surfaces, impairing pad stability and life.
  • Loss of comfort/damping features: If design features like damping plates or proper backing-plates are compromised, then vibration, noise or uneven wear may emerge—reducing the pad’s effective lifespan or creating failure symptoms.

Why they should be replaced
  • Maintain stopping power and safety: To retain predictable braking distances, consistent pedal feel and full system responsiveness, the pad set must operate within specification. Once friction material wears beyond safe limits, system performance suffers.
  • Protect the rest of the braking system: Worn or failing pads can lead to disc damage, caliper piston overheating, or uneven rotor wear—resulting in higher repair costs down the line.
  • Preserve refinement and driving comfort: The pb:z pad set offers smooth, quiet operation with minimal noise or vibration. Replacing at the correct time preserves that comfort and refined braking feel.
  • Conform to regulatory and planned performance standards: Since these pads are designed to comply with ECE R90 and built to high-precision standards, replacing them at appropriate intervals ensures you retain this benchmark level of braking behaviour and safety.
  • Match the development pedigree: These pads result from advanced development cycles (2-3 years plus extensive testing) and represent a replacement-grade compared to generic alternatives. Choosing timely replacement helps you maintain performance aligned with original design intent.
