The caliper body is machined from high quality aluminum and consists of two mechanically joined parts. Brembo engineers focused on maximizing braking power and stiffness using racing-acquired technologies. The calipers cut from the mass allow for equal rigidity to obtain an increase in power with a reduction in total weight. In addition, they have a small footprint.
In the GP4-RX version, the pads slide in the caliper body on special guides machined directly into the caliper body itself. This solution made it possible to eliminate the insert axes.
The GP4-RX is the first product to use a nickel surface treatment derived from MotoGP. In addition to giving the caliper a very attractive look, the nickel coating helped to further reduce the already tight machining tolerances, bringing benefits in performance and precision.
The hydraulic system has been carefully optimized, and the use of four 32 mm diameter pistons has further increased the already famous power and control of the Brembo calipers.
The product, delivered in kit form, is composed of:
