FAQ

Does this brake set come with a hose?

Yes. This J-kit includes a pre-bled SM-BH90-SS hose (1000mm, 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 front 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.
