THE CHALLENGE: AN ALPINE DESCENT ON THE STELVIO PASS

First-class brake pads are subjected to strict and complex tests. Ultimately, premium pads should pass all the tests with flying colours, both in terms of safety and comfort. Textar brake pads are put through their paces in the laboratory, on high-tech test benches, and most importantly on the road.

Textar experts also go one step further and conduct intense road testing on an Alpine descent called the Stelvio Pass – the second highest tarmacked mountain pass in the Italian Alps. With dizzying heights and steep slopes, these roads are a particular challenge for both man and technology.

Pedal force, friction coefficient and brake wear were all tested and put head to head with two other well-known OE brake pad manufacturers.

The Textar test drivers mastered 18 kilometres of winding road with 15% incline. The Stelio Pass is known for its high volume of traf c, with lots of tourists, caravans and cyclists. In 2007, it was chosen as the ”greatest driving road in the world” by Top Gear magazine because the route allows a sporty driving style in spectacular surroundings – optimum requirements for an extreme brake test.

THE TEST PHASE: BRAKE TESTING AT ALTITUDE

Alpine descents put a strain on any brake pad and to master the winding roads, constant braking is required. A reduced braking distance can mean the difference between life and death.

In this practical challenge, the average pedal feel was checked throughout the course of the test.

Due to the increasing brake disc temperature during the descent – up to extremes of 700 °C – the friction coefficient of the brake pads decreases, and the wear rate increases. In order to maintain the braking power, i.e. a consistent deceleration, the driver must increase the pedal pressure.

In addition, the friction coefficient of the brake pads was examined after a certain rest period, to determine what friction coefficient the brake pads can achieve after such a strenuous descent.

  • Could the Textar brake pads defy the intense heat?
  • What friction coefficients were determined?

Important questions. The test results show the answers.

THE RESULTS: TEXTAR DOMINATES THE COMPETITION

Average pedal force

In a competitive comparison with well-known OE makes, Textar prevails. With an average pedal force of 45 N during the Alpine descent, Textar showed the lowest pedal force at 40 N. Thus, the test driver needs to apply less force during the descent. A serious advantage. Particularly in suddenly occurring dangerous situations.

Competitor A 45N
Competitor B 50N

Friction coefficient test

In order to determine the friction coefficient after the test, braking is resumed after the brake system has cooled down. In this way we can determine what level of performance the brake pad can achieve after the descent. The higher the friction coefficient after the descent, the lower the pedal force during braking. Lower friction coefficients can significantly increase the braking distance when panic braking. Two reasons are quickly identified: poor response of the brake and a higher pedal force is required.

In this discipline, Textar once again prevailed against the competition, and achieved the highest friction coefficient with 0.46 μ. In contrast to the average friction coefficient of 0.39 μ. In practice this means: while the vehicle with Textar brake pads has already come to a stop, the competitors have not. A crucial factor, especially in extreme situations.

This is why Textar continually develops and invests in its braking technologies. The brake pads are conceived in such a way that they increase the friction coefficient during sharp braking, meaning that the pedal force does not need to be increased, providing the driver with an increased feeling of safety.

Heat wear test

Textar is also ahead in terms of heat wear. The test results are compiled from two descents. In spite of the very high braking temperatures, Textar displayed the lowest wear to the brake pads, with 0.74 mm. By comparison, the average value was 1.53 mm.

Competitor A 2,18 mm

THE CONCLUSION: TEXTAR SHINES WITH IMPRESSIVE RESULTS

Whether pedal force, wear or friction coefficient, Textar is in the lead during the Alpine descent on the Stelvio Pass, in comparison with other well-known brake pad manufacturers. The test results confirm the high quality standards of the Textar brand for maximum safety and optimum braking comfort.
