The Tectonic brake pad is a forged alloy holder that allows the rider to customize the exact positioning of the friction materials. The friction inserts are designed to interlock together and are secured into the holder on all sides. The Pad-Lock™ washer system has been improved by incorporating the convex pivot adjustment into the backing plate; thus allowing for the reduction in the number of washers needed to achieve all spacing requirements.
