GP4-MS Monobloc Radial Calipers w/ 30mm Pistons

The Brembo GP4-MS Radial Calipers bring MotoGP-inspired technology to the road. These calipers are the first Brembo caliper to combine monobloc construction with being machined from solid aluminum alloy. This process allows for superior mechanical characteristics and high-temperature resistance compared to cast components, resulting in improved braking system performance. Featuring four 30mm diameter aluminum pistons, the GP4-MS calipers redefine road caliper performance, closely matching that of MotoGP versions. The design incorporates topological optimization, derived from Brembo's racing experience, ensuring exceptional rigidity, reduced weight, and minimal deformation under high temperatures. The nickel surface finishing not only provides an attractive aesthetic but also adheres to strict manufacturing tolerances for optimal performance and precision. Each caliper mounts four 30mm aluminum pistons and includes pads. These calipers are designed for a 100mm mounting center and are compatible with OEM discs, Brembo Serie Oro, Brembo Racing SuperSport, and T-Drive discs with a 5.5mm thickness. The offset is 30mm. The ABS system is calibrated for OEM calipers, and replacing them with aftermarket models can alter hydraulic and dynamic characteristics, potentially affecting ABS modulation, detection, and intervention timing. Brembo recommends verifying ABS compatibility on a case-by-case basis through owner forums or user groups. For street use, the Brembo 17RCS master cylinder is recommended (compatible with ABS), while the 19x16 is recommended for track use (not compatible with ABS). The product is not street legal and intended for exhibition in private places unless explicitly stated otherwise.
