The biggest feature of this "FULL monoblock caliper" is the capless design, which was developed without any compromise in structure, performance and durability. The capless full mono body is manufactured by "angle head processing machine". By adopting this method, it is possible to reduce the number of rubber parts, reduce liquid loss, and design a highly rigid and lightweight caliper. The pad spring is used to reduce rattle noise, and the ultra-thin piston is equipped with large diameter dust boots to meet the required specifications for both street and circuit use. The genuine brake disc can be used as it is, and the brake pad is designed exclusively for full monocoque, and uses friction material that supports from street to winding.
