TMD Friction has launched a new friction material for heavy-duty applications using air disc brakes.
The material is designated Textar T3080 and is engineered for applications where high torque levels are required to meet FMVSS121 stopping distance regulations. Textar T3080 already meets the 2014 and 2021 “Better Brakes Rules” environmental regulations for heavy metals and copper content.
Multiple friction levels are required to best optimize pad and rotor life for different truck, tractor, and trailer applications. T3080 rounds out Textar's North American air disc brake friction product portfolio by adding a material for the most extreme torque applications on the road.
In dynamometer wear tests, two air disc friction materials with different effective coefficients of friction were tested by TMD. Results showed that with a higher effective coefficient of friction (0.38) the pad wears anywhere from 40% to 80% more than the lower friction pad (0.28).
“Given the large difference in wear rates between the high and low ends of the typical friction range, it is important to select the appropriate friction level in order to maximize pad life,rotor life and maintain safety,” said Jim Clark, TMD director of engineering for NAFTA. “This is why TMD has developed multiple friction materials for North America, Textar — T3050, T3070, and T3080. They cover all the GAWR ratings. We also offer a special material, one of the European market leaders Textar T7400, for the transit bus and refuse truck market.”
The Textar T3080 air disc brake pad is also the first of a new generation of low copper friction materials from TMD that are compliant with the upcoming 2014 and 2021 environmental regulations in Washington and California.
