Shimano Deore BL-M4100/BR-MT420 Disc Brake and Lever - Front, Hydraulic, Resin Pads, Gray

This 4-piston disc brake from Shimano, the Deore BR-MT420 caliper with BL-M4100 lever, front hydraulic, gives trail riders extra stopping power at the Deore tier. The 4-piston BR-MT420 caliper adds bite over a 2-piston brake, which helps on longer or steeper descents.

The BL-M4100 lever is I-SPEC EV compatible for a tidy cockpit and offers adjustable free stroke to tune lever throw. The brake runs mineral oil, ships pre-bled, and uses non-finned D03S resin pads for quiet, controlled braking. Its front configuration routes about a 1000mm hose, and the gray finish keeps a clean look.

As the Deore tier of Shimano's mountain lineup, this 4-piston front brake gives budget-minded trail riders more power than a 2-piston setup.
