Four pistons for XT: the BR-M8020 disc brake by Shimano

Designed to offer increased braking performance to aggressive trail riders and E-MTB riders alike, the Deore XT BR-M8020 4-Piston Hydraulic Disc Brake Caliper provides 20-percent increased power when compared to the BR-M8000 2-piston Hydraulic Disc Brake Caliper. Compatible with the existing Deore XT M8000 lever, the addition of the 4-piston calipers gives riders additional tuning options.

Servo Wave
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.

I-Spec II
These levers are fit with the 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 or I-Spec EV shifters.

One Way Bleeding
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 bubble 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.

verified purchase

Fahre jetzt mit Kombi XT 4 Kolben Vorne und die 2 Kolben XT hnten. Bin jetzt mehrmals im Gebirge Kroatiens gefahren und ist enorme Verbesserung für mich. Wiege über 90 kg und die Bremse kam nie ans Limit, im Vergleich dazu ist die Deore schwächer. Danke an BC für den vorab Test, kann es nur bestätigen. Das Wandern des Druckpunktes kann ich nicht bestätigen, muss noch dazu sagen dass ich die Bremse vorher noch entlüftet habe.
