Nine reasons to fit genuine brake pads
The braking system is the most important safety aspect of a vehicle which should not be compromised.
Fitting accuracy
With Volkswagen genuine brake pads, nothing has to be ground down or readjusted if they are installed in a Volkswagen. They fit out of the box and can be installed in no time which saves cost and rules out any malfunction. The required sundry items are included so old securing material and clips are ruled out for maximum safety.
Braking power
The maximum braking power on a Golf GTI with maximum load and top speed is six times the engine output. Even with glowing brake discs the brake pads must still transfer the braking power.
Temperature load
Volkswagen genuine brake pads are designed to withstand more than 800°C basic temperature and up to 4,000°C in the micro range at the so-called hot spots. They can also withstand up to minus 50°C without losing noticeable friction. Expansion, shrinkage, bending or cracking would also lead to considerable malfunctions.
Fading
Incorrect composition of the brake lining material and also some universal mixtures without special optimisation for the specific vehicle lead to the feared “fading” phenomena particularly easily. Here, gas emissions can occur where a cloud of gas forms between the brake discs and brake lining and reduces the friction coefficient rapidly.
Heat insulation and pressure
Volkswagen genuine brake pads keep the (at times) extremely high temperatures of the brake discs away from the brake cylinders. And they thereby prevent vapour bubbles from forming in the brake fluid that could lead to failure of the braking system. The pads are pressed against the brake disc during braking with a force equal to 1,000 kg.
Resistance to harmful substances
In addition to temperature and pressure influences, the brake pads are also subjected to chemicals at the same time.
Volkswagen genuine brake pads withstand salt, brake fluid, fuel and much more without losing their braking properties.

Friction coefficient
The friction coefficient is a decisive factor on the stopping distance. During construction of the braking system, the friction coefficient is set individually by the vehicle manufacturer for each vehicle model. To ensure that the specifications for Volkswagen genuine brake pads are adhered to there are comprehensive testing programmes, audits and process checks for quality assurance.
Qualities checked are:
• Friction coefficient change as disc temperature rises and falls,
• Friction coefficient change following multiple brake actuations,
• Friction coefficient change at different speeds,
• Friction coefficient change under the influence of damp and salt.
Dynamometer test beds are used for testing as well as automatic, computer controlled programs.
This way, extreme driving situations for different vehicle models can be simulated. Volkswagen genuine brake pads are not standard universal products. They have been optimised for the overall weight to be braked of each Volkswagen model. In the same way as for brake pressure limiters and braking systems that are installed in our models.
Comfort response
Safety and braking power are of course the most important criteria against which a lining must measure itself. Under no circumstances would brakes be acceptable if they caused noises each time they were used. Or if vibrations were noticed at the brake pedal. 
Material composition
About twenty different raw materials are processed in Volkswagen genuine brake pads. In addition to different metal alloy fragments to support the friction coefficient there are also a wide range of lubricating and filler materials, fibres and binding agents. They also decide the resistance to wear and comfort response. In the Volkswagen genuine brake pads, textile glass fibres and aramide fibres such as Kevlar, for example, are bonded together by duroplastics and elastomers.
