What is in the Shimano Deore BR-M6100 Rear Brake Set?

The Shimano Deore BL-M6100/BR-M6100 is a 12-speed-era hydraulic disc brake that pairs the BL-M6100 lever with the BR-M6100 2-piston caliper as a matched rear system. The lever uses Shimano SERVO WAVE action, which moves the pads to the rotor quickly at the start of the stroke and leaves more lever travel for modulation, so engagement is fast and control is predictable. It is I-SPEC EV compatible for a clean cockpit with matching Deore shifters, has tool-based reach adjust, and runs on Shimano mineral oil. This is the rear half, built around the right/rear lever.

It ships as a pre-bled J-kit: caliper, lever, mounting hardware, and a pre-bled SM-BH90-SS hose (1700mm, black) with connector insert are all included, so installation is fast and internal routing is straightforward. The caliper is post mount and ships with metal pads (no fin). No rotor adapter is included, so add a post-mount adapter to match your rotor size. Funnel bleeding keeps maintenance simple. A strong, low-maintenance stopping setup for trail and all-mountain builds.

FAQ

Does this brake set come with a hose?

Yes. This J-kit includes a pre-bled SM-BH90-SS hose (1700mm, black) with a connector insert, so it is ready to install. No rotor adapter is included, so add a post-mount adapter to match your rotor size.

What rotor sizes work with the BR-M6100 caliper?

The BR-M6100 post-mount caliper runs 160mm, 180mm, and 203mm rotors using the correct post-mount adapter. Many trail bikes run 180mm front and 160mm or 180mm rear, and heavier or faster riders often size up.

Is the BR-M6100 compatible with other Shimano hydraulic MTB parts?

Yes. The M6100 lever and caliper use Shimano mineral oil and are compatible with other Shimano hydraulic MTB disc components in the mineral-oil family, and the lever is I-SPEC EV compatible with matching Deore shifters.

Best For

Trail and all-mountain riders building or replacing a rear hydraulic disc brake who want a complete, pre-bled Shimano lever-and-caliper J-kit with SERVO WAVE feel and low-maintenance mineral-oil hydraulics.
