The XTR BR-M9020 disc brake set by Shimano - for even better heat control
The Shimano XTR BR-M9020 Trail disc brake set (front + rear) impresses with particularly stiff mono-body brake calipers made of aluminium as well as metal pads with cooling fins, making it particularly suitable for use in the All Mountain and Enduro sector. The insulated ceramic pistons (fibreglass-phenol) - two on each caliper - are 10% more heat resistant than their predecessors and keep braking performance stable under extreme conditions thanks to optimum heat control. This is because of the Ice-Tech system, which was developed after extensive tests on heat, power and stiffness of the various brake components. Of course, with One Way Bleeding, the calipers are very easy to bleed. On the BL-M9020 2-finger brake levers, the reach can be adjusted without tools and the contact point can also be changed. The levers come with I-Spec II technology, i.e. they can be mounted together with shifters and aligned in a wide variety of ways.

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 XTR M9000 levers are compatible with the I-Spec II system, that allows to mount the shift and brake lever on the handlebar with only a clamp. This gives more freedom in the cockpit-design, save weight and improves the ergonomics thanks to diverse adjustment possibilities. Simple structure with narrow brake lever clamp band. More space on handle bar and cleaner appearance. Max. adjustment range vertical: 15°, max. adjustment range horizontal: 12 mm. I-Spec II brakes are not compatible with I-Spec, I-Spec B or I-Spec EV shifters (or vice versa).
One-Way-Bleeding was developed for quick and easy prevention of air in Shimano's hydraulic system. They have 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.
Brake fading during prolonged uninterrupted operation, e.g. downhill, impairs braking performance. Shimano has introduced brake discs and pads with Ice-Tech technology to create a cooling technology for consistently high braking performance. The brake rotor has a three-layer stainless steel sandwich structure on the outside around an aluminium core. It radiates heat better and reduces a surface temperature from 400° C to 300° C, for example. The brake pads also have optional cooling fins. The design of the rotor in combination with the cooling fins results in a longer service life of the pads, less braking noise, less fading and a lower weight.
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.
