There is always a difficulty of securing efficient working owing to the great heat generated and the varying peripheral speeds. These difficulties have been solved by the use of Ferodo fabrics. At a large colliery in Scotland where constant trouble was experienced with V brakes, we fitted I Ferodo fabrics over four years ago, and they are still working efficiently without further trouble. If you have any brake troubles write us. We can solve them. IHBEBEEI Clutch and Brake Linings.
