One of our key products here at Frenos Sauleda are friction buttons, used for various applications, from American heavy duty pick-up trucks to high powered vehicles used in drag or drift racing. We manufacture these both with a high copper contained quality (yarn based) in our formulations. Thousands of pieces are sold every month. Our formations at our company give many advantages over the more common sintered pieces usually found on the market. Above all, the greatest advantage is the smooth engagement aquired, which means driving comfort. High resistence plays an important role and is something to take into consideration.
