SHIMANO DEORE BL-M4100 / BR-MT420 4-PISTON DISC BRAKE SET (FRONT & REAR | SHORTENED HOSES | POST MOUNT | D03S RESIN | BLACK)
The Shimano Deore M4100 / MT420 disc brake set provides powerful 4-piston braking performance for demanding trail, enduro, and e-MTB applications. This offer includes the **complete set for front and rear wheels (FW + RW)**. The BR-MT420 4-piston brake calipers offer excellent reliability, outstanding heat resistance, and precise modulation in steep terrain.
The brake hoses of this system have **already been shortened to a practical length** (front hose approx. 86 cm, rear hose approx. 158 cm). The ergonomics of the BL-M4100 2-finger aluminum brake levers, combined with intuitive responsiveness and I-Spec EV compatibility, ensure a tidy cockpit.
Important installation note:
As the brake hoses have been shortened, a new olive and insert pin (model SM-BH90) will be required for the final installation on your frame or for any further adjustments, and the system must be bled.
