Shimano M4100 front MTB disc brake (without disc) - EMT4101JLFPRA100

The DEORE M4100 front MTB disc brake ( Shimano, part number EMT4101JLFPRA100 ) is a hydraulic braking system designed to deliver powerful, progressive and intuitive braking on mountain bikes. It combines the DEORE BL-M4100 ‘ Shimano ’ lever withthe 2-piston BR-MT410 ‘ Shimano ’ caliper, connected by a 1000 mm hydraulic hose.

Intended for the front wheel, this DEORE M4100 ‘ Shimano ’ brake is an excellent solution for replacing or upgrading the braking system on a mountain bike fitted with hydraulic disc brakes. Its two-finger lever offers an ergonomic grip and precise braking control.

The BL-M4100 lever features a quick response and reduced free travel, resulting in more intuitive braking and better control over the available braking power. The BR-MT410 2-piston caliper effectively complements this set-up for XC, sport touring and All-Mountain mountain biking.

A versatile Shimano hydraulic brake for mountain biking

The Shimano DEORE M4100 has been developed to offer an excellent balance between power, control and ease of use. The hydraulic operation ensures a smooth transfer of force from the lever to the caliper, whilst the twin pistons deliver effective pressure to the brake pads.

The design of the BL-M4100 lever prioritises a fast and direct braking feel. Its short free travel allows the rider to engage the brake quickly and modulate their braking effort more easily on technical sections.

The unit is particularly well-suited to riders seeking a reliable, high- Shimano e front brake for mountain biking, whether as a replacement for the original brake, for a refurbishment, or as part of an upgrade to the braking system.

Compatibility and fitting

Part number EMT4101JLFPRA100 corresponds to the front version with a 1000 mm hydraulic hose. The set includes the BL-M4100 lever, the BR-MT410 caliper, the hydraulic hose, the brake pads and the components required to connect the system.

The brake disc and adapter are not included. You should therefore select a rotor separately and, if necessary, an adapter that matches the disc’s diameter and the fork’s mounting standard.

Before fitting, it is recommended that you check the required hose length, the fork mounting standard and the compatibility of the disc with the caliper.
