Shimano Deore BR-M6120/BL-M6100 J-Kit Rear Disc Brake and Left Lever

Intuitive Braking
With quicker brake engagement and shorter free stroke, the Shimano Deore BL-M6100 brake lever delivers intuitive braking so you can stay focused on the trail ahead. The I-SPEC EV shift lever, with 10 deg. rotation angle setting range, offers a wider adjustment range for superior rider tuning. Shimano's Deore M6120 caliper features consistent braking performance and reliable stopping power in all conditions. The 4-piston caliper instills greater downhill confidence and control.

J-Kit
J-Kit is a simple hose connection system for hydraulic brakes on internally routed hoses so that you can install your brake quickly and easily. The brake hose does not come connected to the brake to facilitate the 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.

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.

One-Way-Bleeding
One Way Bleeding is a technique used on the brake calliper that makes it easier to bleed the brake. 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.
