The best brake made even better: the XT Disc Brake BR-M8000 from Shimano
The Deore XT disc brakes are known industry wide for being the high-end, but cost effective choice. Always reliable with enormous breaking power the new Deore XT M8000 has a lighter more robust main cylinder that has been seamlessly integrated into the system. Now the typical XT-cockpit has a sleeker look with more free space on the handlebars. The revised Servo Wave lever offers better response and braking power with a short lever. Every part of this braking system can be adjusted including the reach, and pressure point. The small clamp allows the brake lever to be attached in various positions at different points on the handlebars. With rotor size ranging from 140 to 203 mm and the choice of various brake pads the XT M8000 is truly “Rider Tuned.”

When you pull a Servo Wave brake lever initial pad travel is fast, so little lever movement is needed to bring the pads into contact with the rotor. The power multiplication factor then increases rapidly at the pad-to-rim contact so more of the lever stroke is used to apply greater braking power with improved control.
The XT levers are fit with the new I-Spec II system. This system combines the shifter and brake lever into one clamp that can be mounted on the handlebars. I-Spec II gives more freedom in cockpit placement, saves weight, and more mounting possibilities for a more ergonomic design. Easily installed with smaller clamps leaving more space on the handlebars. Maximum adjustment parameters: vertical 15°, horizontal 12 mm. I-Spec II brakes are not compatible with I-Spec or I-Spec B shifters.
One Way Bleeding was developed for quick and easy prevention of air in Shimano’s hydraulic system. Shimano has streamlined the oil route throughout the system to prevent air bubbles from being captured in the system. One way oil routing plus a funnel tool with mineral oil provides an easy and clean bleeding system.
The fade, which can occur to rotor and pad when braking on a long downhill ride for instance, has a negative impact on the braking performance. Shimano has adopted Ice Technology rotors and Ice Technology pads to realize the cooling technology for consistent performance. The rotor blade, which has a 3 layer-sandwich structure of stainless steel, aluminum and stainless steel, provides better radiation performance achieving from 400 °C to 300°C surface temperature. Also, the radiation fin has been adopted for the pad. Moreover, the rotor blade and the radiator fin provide long pad life, less noise, less fade and are lightweight.
XTR, Saint, Deore XT, SLX, Zee, Deore LX calipers are bundled with Ice Technology pistons in order to achieve optimized lightweight, high rigidity and heat dissipation. Oversized pistons transfer hydraulic power directly to the brake pad, and ceramic material is used to avoid heat transfer for constant stable braking, providing efficient stopping power transfer without loss.
