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.
