Shimano XT BR-M8120 / BR-M8100 Disc Brake Set w/ Resin Pads J-Kit

Shimano XT BR-M8120 / BR-M8100 resin disc brake set - bites even harder up front

With the Shimano XT BR-M8120 / BR-M8100 disc brake set you get a bundle of a four-piston brake for front and a two-piston brake for rear - each with organic brake pads. This gives you an extra portion of brake power on the front wheel, which Shimano has specially tuned for Enduro and Trail use. On the other hand, the 2-piston system at the rear saves some weight. Both calipers feature excellent brake control and a simple connection system. The I-Spec EV compatible BL-M8100 brake levers are mounted at an angle to provide an additional contact point. This increases stiffness and provides more direct feedback. Shimano Servo Wave also enhances braking performance: you can get more performance out of a 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.
