Tarox releases carbon ceramic brake range
Italian brake manufacturer Tarox has launched its carbon ceramic ultra-high performance braking range. The new discs draw on the company’s motorsport experience, which extends to Formula One. The company says the new parts are marketed as aftermarket replacements for vehicles factory fitted with carbon ceramic discs and as specialist motorsport fitments alongside Tarox callipers. The range launched with 23 fitments, covering outside diameters from 283mm to 420mm and featuring a wide range of thicknesses from 26mm to 40mm. The range starts at £2210+VAT per disc.
According to the company, carbon ceramic brakes offer significantly greater retardation over a wide heat range; the discs feature a continuous monolithic fibre structure that avoids the need of a specified layer of friction material. This construction method strengthens disc structure and allows the disc to be resurfaced and reused.
This method compares with other commercially available carbon ceramic discs made from a two part moulded cut fibre structure featuring a core and a friction surface. The core is usually a lesser material with typically, a 0.5mm bonded layer of friction material bonded on top. Tarox’s carbon ceramic discs’ structure allow for higher thermal conductivity, meaning the brake rotor achieves lower bulk temperatures during braking. Cooler running temperatures lower the oxidation rate of the disc, improving its lifespan, and that of the brake pad. When compared with a typical composite ceramic disc Tarox says its discs are 43 per cent stronger when destruction-tested back to back:
• Tarox carbon ceramic disc: 23.7 kJ of energy required at 7400 rpm (560mph)
• Typical carbon ceramic disc: 16.6 kJ of energy required at 6250 rpm (470mph)
Dyno tested against typical ceramic discs to monitor deterioration at key temperature ranges, Tarox carbon ceramic discs produced equally impressive figures:
• Tarox carbon ceramic disc: Four hour cycle at 900°C resulted in a 12.5 per cent loss of weight
• Typical carbon ceramic disc: Four hour cycle at 900°C resulted in a 19 per cent loss of weight
• Tarox carbon ceramic disc: Four hour cycle at 700°C resulted in a 7.5 per cent loss of weight
• Typical carbon ceramic disc: Four hour cycle at 700°C resulted in a 15 per cent loss of weight
