Shimano XT BR-M8120 + BL-T8100 Disc Brake J-Kit

The Shimano XT BR-M8120 Disc Brake with BL-T8100 3-finger Brake Lever

This version of the XT BR-M8120 disc brake from Shimano comes with the BL-T8100 3-finger brake lever, which impresses with very good operability and braking dosage. It is compatible with I-Spec II shifters, which can be installed on the same mount to save space. The handle width can be adjusted without tools. The BR-M8120 is a four-piston caliper with organic cooling-fin brake pads specially designed for enduro and trail riding. It features excellent brake control and a simple connection system. That way, you can give your full attention to the challenges of the terrain.

Technology:

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.

I-Spec II
I-Spec II describes a variant of the connection between the brake lever and the shift lever on MTB or, more precisely, flatbar gears from Shimano. This type of mount makes for a tidy cockpit as it reduces the number of clamps needed. On some models it is also possible to adjust the shift lever both horizontally and vertically in relation to the brake lever. Then there is 12 mm of adjustment travel in the longitudinal direction and/or up to 15° of rotation - for optimum ergonomic adaptation to your riding style, seat position and anatomy.

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.
