Shimano XT BR-M8100 Disc Brake w/ Sintered Pads J-Kit

The Shimano XT BR-M8100 disc brake - so you can concentrate fully on the trail

The Shimano XT BR-M8100 is a two-piston disc brake with sintered brake pads specially designed for Cross Country use. The brake caliper features excellent brake control and a simple connection system. The I-Spec EV compatible BL-M8100 brake lever is mounted at an angle to provide an additional contact point. This increases stiffness and provides more direct feedback. In addition, Shimano Servo Wave increases braking power: more performance is available with shorter empty travel.

Technology:

Servo Wave
Shimano Servo Wave technology optimises the travel of your brake levers. During the braking process, the brake pads are guided quickly to the brake rotor with very short lever travel. The greater part of the lever travel is reserved for the actual braking force. In this way, you can apply your braking power in a more targeted manner and use it more effectively.

I-Spec EV
I-Spec EV describes a variant of the connection between brake lever and shift lever on Shimano MTB derailleurs. This type of mounting allows the shifter to be adjusted both horizontally and vertically in relation to the brake lever, and ensures a tidy cockpit by reducing the number of clamps required. Compared to I-Spec and I-Spec II, I-Spec EV offers a much wider adjustment range. 14 mm adjustment range the longitudinal direction and up to 60° rotation allow an optimal ergonomic adjustment to your riding style, your sitting position and your anatomy.

One-Way Bleeding
One Way Bleeding is a technique used on Shimano calipers that facilitates brake bleeding. The hose routing has been optimised so that no air bubbles remain in the brake calliper. In combination with the funnel, the brake can be bled cleanly and easily.

J-Kit
J-Kit is a simple line connection system for hydraulic brakes from Shimano, so that you can install your brakes quickly and easily. The brake hose does not come connected to the brake to facilitate routing of the hose in the frame. The brake hose is already filled with oil in the J-Kit and sealed with a thin membrane. There is a small pin in the J-Kit brake lever that pierces this diaphragm during assembly to allow oil to flow.
