The race inspired Brembo GT | S M6 and M4 calipers are perfect for the club racer or weekend track day enthusiast that wants to take that next step in braking. The M6 is a six-piston aluminium front caliper with performance properties gleaned from the company’s endurance caliper that helped the Ford GT win the 24 Hours of Le Mans.

The pistons include racing style radiators and dual inner piston seals, with an inner pressure seal and an outer wiper seal. This innovative design provides the best combination of performance and long-lasting track use. The calipers are hard anodized for longevity and resistance to corrosion at high temperatures. The Brembo logo is racing style, engraved in red, as seen on all of the company’s competition products.
 

​This is a braking system made of motorsports-derived components that stands out for its high technology and performance. The kit consists of aluminium brake calipers with opposed pistons and one-piece or composite oversized discs that may be drilled or slotted. 

The Brembo GT | S kit is designed and tested specifically for track day enthusiasts and for drivers who demand the utmost performance from their cars. These kits offer superlative performance for both normal driving and demanding track day sessions. Brembo kits consist of cross-drilled or slotted ventilated, integral or composite discs and aluminium calipers with 4, 6 or 8 pistons; a complete set of high performance pads; metal-braided hoses and high quality hardware. 

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. Additionally, the discs may be floating or one-piece, depending on the car model. The kit also includes a set of high performance pads, DOT approved metal-braided hoses, the adapter and high quality fastening hardware. ​

The radial-mounted fixed calipers and the oversized discs give the brakes more braking torque and greater thermal capacity. The result is more responsive, decisive braking that can be perceived even during normal road usage but that is also consistent on the simple sections of 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. Finally, due to the aluminium alloy bell, the system with oversized floating disc reduces the unsprung weight (for improved handling) and thermal stress. The mounting system is engineered to permit a greater degree of both radial and axial float. 

This feature adds to the larger braking surface and allows better dissipation of the heat that is generated by the repeated, intense thermal stress that the discs have to withstand. This keeps the braking performance and pedal feel consistent even after several laps. 

The counterfeiting of Brembo brake systems, as with many products made by the most iconic brands, is unfortunately something that is becoming more and more widespread. In this case, it is something that is potentially much more dangerous because it regards the performance of active safety systems which are vital to the safety of drivers, passengers and other road users. 

Brembo has always guaranteed the safety and reliability of its own parts and has developed an app called Brembo Check which can be used simply and quickly to certify that its products are genuine ones. 

With Brembo Check installed on your mobile device, all you have to do when you buy an UPGRADE product is use your smartphone to scan the unique QR Code on the label which can easily be seen on the purchased component or on the box, as in the SPORT range, to know if the Brembo product is original or not. 

To prevent tampering, the label is made using a printing and application procedure which prevents it from being removed; if you try to remove it, you damage the QR Code making it unusable. In this way, the label cannot be detached and cannot be affixed to any other products other than the original one. ​
