astéria Full Contact Braking

Unique design with unprecedented braking performance!

Conforms and surpasses the New NHTSA regulations (USA) for braking distances (-30%).

The air brake market for trucks and semi-trailers:

– The drum brake is standard equipment on trucks and semi-trailers on the North American and European markets;

– The drum brake is progressively being abandoned because of its poor resistance to overheating and constant tuning of external adjustment systems.

The Achilles' heel of the air disc brake in actual use:

– The air disc brake exists only in a floating calliper design: the actuator is integrated in the calliper to provide adaptation to friction material wear;

– Because of the important mass of the integrated actuator calliper, this type of braking system has poor resistance to shock and road vibrations, leading to irregular functionality, frequent repairs and higher maintenance costs.

The astéria brake was created to address these limitations and more.

The solution :
astéria, the Integral High-Performance disc brake

The astéria brake is composed of a fixed caliper and a floating disc, as utilised in aviation:

– The pneumatic actuator is solidly linked and thus part of the axel;

– The integrated piston generates pressure against the disc onto the external brake pad;

– The disc is guided on a floating hub design.

The friction material of the brake pads cover the major part of the disc surface, which insures longer friction and disc life.
It is many more times superior when compared to the integrated actuator floating calliper design and resembles drum brake friction material life span.

The advantages of the Integral
High-Performance astéria Brake:

1. Integrates in a 22.5 inch front wheel

2. Weight advantage is attributed to aluminum construction

3. Brake mechanism protected by international PCT patent

4. Higher driving safety is insured by more braking power

5. Costs savings : prolonged friction material life span

6. Costs savings: prolonged disc life

7. Reduced brake maintenance/servicing

8. Better safety is achieved through higher resistance to brake fade

9. Robust design attributed to actuator solidly linked to axel

10. Robust direct disc guidance

11. Easy friction material servicing

12. Easy inspection of rotor and pads

13. Extreme capacity and robust construction

14. Extended service with aluminum wheel profile

15. Protection of disc and brake pads against foreign matter: rocks, mud, sand, etc.

16. Simple and powerful clamping concept

17. "Automobile'' type braking performance

18. Compatibility with drum brakes
