What they do:
- The pads are engineered to convert kinetic energy into thermal energy by pressing against the brake disc—a controlled friction process that brings the vehicle to a stop with minimal fade and consistent feel.
- ZIMMERMANN uses friction-material mixtures drawn from up to 25 different raw-material types, tailored to vehicle and braking system demands.
- The result is a braking solution that boasts long lifespan, very smooth performance, and largely conforms to ECE R90 standards for defined braking behaviour and safety.
- Comfort-oriented features—such as damping plates, directional bevels, grooves and tuned vibration-absorbing layers—help suppress noise and vibration while maintaining crisp response.
Why brake pads fail:
- Wear-out of friction material: Over time, the pad material becomes thinner and loses its capacity to generate sufficient friction—leading to longer stopping distance and reduced effectiveness.
- Glazing or thermal overload: When subjected to repeated heavy braking or high temperature without proper match to the disc, the pad surface can harden (glaze) or lose its ideal friction coefficient, reducing deceleration.
- Uneven contact or mismatch: If the pad and disc aren’t perfectly paired (material mismatch, incorrect installation, warped disc) then only part of the pad surface may work, causing hotspots, uneven wear, vibration or faster failure.
- Loss of comfort/design features: Without the built-in damping/chamfering/tuned geometry, pads may generate noise, harshness, uneven wear or premature damage—especially in compact performance systems where tolerances are tight.
Why they should be replaced:
- Ensuring the braking system delivers its designed stopping power means you maintain safe deceleration, consistent pedal feel and proper response under emergency or repeated use.
- Replacing before performance degrades protects other components—worn pads can harm the brake discs, calipers or result in higher repair cost.
- Comfort and refinement are part of the product promise: the ZIMMERMANN pad set’s smooth operation and low-noise design mean you preserve vehicle refinement, not just raw performance.
- Compliance matters: Because the pads largely conform to ECE R90, using a worn or incompatible pad may move you away from the standardised braking behaviour expected for your vehicle, especially important in high-end or performance cars.
- The development pedigree behind the pads (2–3 years of development cycles, extensive test-miles) means the replacement component offers replacement-grade quality rather than a generic substitute.

- OES quality Long service life
- Smooth and consistent braking performance
- Complies with ECE R90 regulations

- 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.
