Its 12.25-inch diameter and 7.5-inch width set the working size of the friction surface, while the inboard mounting style places the drum behind the hub. The Webb 63631F uses a 10-hole pattern on an 8.75-inch bolt circle. The inboard mount and bolt pattern let the drum fasten to the hub while keeping the shoe-contact surface aligned with the brake assembly.
