EBC brake pads contain Aramid fibers, these are man-made high performance fibers, used widely for their light weight, high strength, abrasion resistance and thermal stability. They are used as reinforcements in ballistic protection (bullet-proof helmets and vests, vehicle armor), cut resistant gloves, aircraft and marine structural parts, power transmission belts and of course friction products where their high strength to weight, thermal stability and abrasion resistance provide advantages over cheaper steel fiber based products.
