Brembo BM 4 Piston Front Big Brake Kit - 345x28mm 2-Piece Rotor

GT | BM4 Brake Kit

Designed with you in mind, who always seeks the best for your car, the GT | BM4 kit is the latest expression of Brembo's style with innovative technology and a design with exclusive geometries typical of the racing world.

The caliper is machined from a single billet of aluminum that has been cast in Brembo's foundry. This ensures outstanding rigidity and minimized deformation. Moreover, the discs that are provided in the kit have a unique ventilation system that improves the cooling capacity and increases by over 40% the resistance to the cracking that is caused by thermal shock.

GT | BM kit have a design level that is unparalleled on the market. The GT | BM kits’painted calipers (available in: Red, Black, White, Yellow and Neon Yellow) that display Brembo's logo together with the slotted or drilled discs give an unmistakably sporty and eye-catching look to the car. This appeals to whoever wants to enhance their vehicle's design and stand out from the crowd.​

The radial-mounted fixed calipers and the oversized discs give the brakes more braking torque and greater thermal capacity. The result is a more immediate and decisive braking that can be noticed even during normal road usage but that is also incredibly powerful and consistent during the many consecutive days spent on the track.

The fixed calipers improve the system's durability and efficiency since the use of several opposed pistons allows an enhanced distribution of the pads' action as well as a more uniform wear on the friction surfaces. The outstanding rigidity of the calipers and the use of metal-braided hoses ensure that brake fluid absorption is reduced. This provides more responsive, stable pressure on the brake pedal thus improving pedal feeling and modulation.

The brake calipers for the GT | BM systems are made using an innovative 4D technology casting process used here for the first time ever in the manufacturing of car calipers. This casting process makes use of a technology that has allowed Brembo to offer a design that is completely different compared to what is generally offered for this type of calipers. With this technology, the caliper has technical features that are generally found only on racing calipers that are machined from billet or forged.

All the calipers in the GT | BM braking systems are cast with internal fluid lines rather than with the more conventional external rigid pipe connections. The bleeding screw is invisible therefore it fits better within the overall design and this ensures greater safety and freedom of design. The family of GT | BM calipers stands out for the higher degree of efficiency in terms of architecture and style thanks to the lack of aesthetic limits that are typical of calipers that are cast using traditional methods.

Brake Discs

Drilled

These discs are distinguished by a unique slot design which combine an eye-catching look with brilliant performance and efficient braking in any condition. Available in one-piece or floating 2-part.

Type 1

TY1 brake discs are distinguished by 8 straight slots that provide superior initial response (bite) with a good pedal feel. These discs provide improved pedal feel and modulation. Available in one-piece or floating 2-part.

Type 3

TY3 brake discs are distinguished by aggressive slotting that provides superior initial response (bite) with a good pedal feel. The discs originate directly from Brembo’s experience in high-end racing and offer improved pedal feel and modulation. Available with or without the Brembo logo.
